The reserves are the backbone of stablecoins. The full backing guarantees that 1 stablecoin token has a redemption value of 1 dollar. The active management of the reservers generates revenue for the issuer. Tether and Circle generated $5.2 billion and $2.7 billion in revenue, respectively. The token holders of USDT and USDC receive zero yield.

The value proposition of yield stablecoins is straightforward: the same dollar denomination, the same downside protection, but with the token’s value appreciating every day as the underlying reserves generate returns. According to StableWatch, the supply of yield-bearing stablecoins has grown from roughly $1.5 billion to more than $11 billion in under two years, making them the fastest growing sector of DeFi.

The recent collapse of Main Street’s msUSD and msY is a reminder that the appeal and the reality of yield-bearing stablecoins are not always the same thing. Understanding the difference matters as much for lending vault allocators as it does for token holders.

What a Yield-Bearing Stablecoin Actually Is

Traditional stablecoins, such as USDC from Circle and USDT from Tether, are designed primarily as transaction and settlement instruments. The reserve capital backing each token is held in bank deposits or short-term government securities. The interest income is held by the issuer, contributing to its revenues. The stablecoin holder receives price stability and liquidity - which, for many use cases, is sufficient.

Yield-bearing stablecoins alter this economic and redistribute the yield earned back to token holders:

• The stablecoin reserves are deployed into a yield-generating strategy.

• The returns are passed through to token holders - most commonly through gradual appreciation in the token’s net asset value (rather than periodic distributions).

Every yield-bearing stablecoin is, in economic terms, an investment product. The yield must originate from a specific strategy, and the nature of that strategy - its risk profile, its liquidity characteristics, its counterparty dependencies - determines the true risk profile of the instrument, independent of how it is marketed or categorized.

The three major yield sources include:

Tokenized Treasury - part of the stablecoin reserves are held in short-term U.S. Treasury bills or equivalent instruments. The yield tracks the risk-free rate, and the risk profile is close to that of a money market fund. These products carry credit and market risk, but the sources of that risk are transparent and, in most cases, subject to established financial regulation.

DeFi lending: reserves are allocated into overcollateralised lending protocols. Borrowers post collateral in excess of the loan value, and the interest flows to stablecoin holders. Yields move with on-chain borrowing demand. The risk profile includes smart contract exposure, liquidation risk in stressed markets, and yield compression when borrowing activity falls.

Synthetic and strategy-based stablecoins generate returns through (perpetual) funding rate capture, delta-neutral derivatives positions, and options strategies. These can offer materially higher yields than the other categories in favourable conditions. They also carry the highest complexity, the most dependence on off-chain counterparties and market conditions.

Examples of yield stablecoins:

• USDY (Ondo Finance) — backed by short-term U.S. Treasury notes and bank deposits. Yield accrues automatically into the token’s price, which appreciates gradually as interest accumulates. No staking required.

• USDM (Mountain Protocol) — also backed by U.S. Treasury bills, but using a rebasing design: the holder’s balance increases daily to reflect interest earned rather than the price per token changing. Fully regulated in Bermuda.

• Noon — backed mostly by Fasanara Capital’s tokenized private credit funds, with proof of reserves provided through Accountable. The underlying exposure is to regulated, auditable real-world credit rather than off-chain strategies.

The msUSD Collapse: What Happened with the Reserves?

Main Street issued two tokens: msUSD, pegged to 1 USD, and msY, a yield-bearing stablecoin. The returns were generated through an active off-chain trading strategy on the reserves. Accountable, a proof-of-reserves provider, was using zero-knowledge proofs to attest to the existence of off-chain reserves of Main Street (without revealing their composition).

The collapse followed a specific sequence.

1. Accountable terminated its verification relationship with Main Street. The reasons were not fully disclosed.

2. As a consequence, market participants could not verify that the off-chain reserves existed. Main Street assured that its stablecoins remain fully backed, but did not provide sufficient arguments.

3. The market price of msUSD and msY collapsed

4. The loss of value of msY caused a bad debt risk and liquidity crunch in Morpho vaults that allowed msY as collateral.

A note on ZK proof of reserves. Accountable and similar services use zero-knowledge cryptography to confirm that assets exist up to a claimed value without disclosing their specific composition. This is a genuine advance, it enables privacy-preserving verification of off-chain holdings. Its limitation is that the attestation is only as reliable as the ongoing relationship between verifier and issuer, and only as current as the most recent attestation.

The Impact on Lending Vaults

The most instructive part of the msUSD story is not the loss of peg itself. it is what happened to lending vaults that had accepted msY as collateral.

As msY’s value declined sharply, borrowers who had posted it as collateral faced liquidation. Depositors who had allocated stablecoins into msY-collateralised vaults moved to withdraw. Market utilisation reached 100% - all deposited capital was already lent out against illiquid collateral. Borrowing rates spiked as the protocol tried to incentivise repayment. Depositors found themselves temporarily unable to exit positions they had every right to exit - not because the collateral had vanished, but because the liquidity to honour withdrawals was not there. This risk is called liquidity crunch.

What is a liquidity crunch? A liquidity crunch in a lending vault occurs when demand for withdrawals exceeds the available undeployed capital. Even where collateral retains some value, a rapid deterioration can trigger simultaneous borrower defaults and depositor redemptions at a scale the vault cannot absorb. The collateral remains on the books; the cash to return to depositors does not.

The lesson for lending vault allocators is direct: a vault’s risk profile depends not only on the accepted collateral, but also - and most importantly - the collateral quality.

A lender who allocates capital into a vault that holds synthetic yield stablecoins as collateral carries indirect exposure to every strategy risk, counterparty dependency, and verification relationship underlying those assets - whether that is visible or not.

How Professional Curators Responded

The msUSD event caused a clear reallocation trend among curators:

• reduce or eliminate exposure to strategy-backed yield stablecoins

• increase allocations toward RWAs, especially tokenized private credit products.

Unlike some yield-bearing stablecoins, tokenized RWAs are often securities (such as funds) and are subject to regulations. At the same time, they bring a new type of risk (default risk), specific to the category.

Why do curators allocate at all to yield tokens or tokenized private credit?

The answer is yield. Whereas the prime vaults allocate only to blue-chip tokens (such as Eth or wrap BTC), their yield is just around 4%. To increase the APY of frontier vaults, curators seek riskier collateral, as it yields higher APYs.

Five Lessons for Investors

Yield always comes with a specific risk. A 12% return from funding rate capture and a 3% return from short-duration Treasury bills are not comparable instruments. Evaluating the strategy is the starting point. The same logic applies to the comparison between DeFi vaults.

A yield-bearing stablecoin is an investment product. A stablecoin can maintain its peg as long as the value of reserves exceeds the value of tokens in circulation.
In a stress event, a synthetic or strategy-backed stablecoin can fall in value (just like any other actively managed strategy) if the reserves lose value.

Dependencies are where risk concentrates. Proof-of-reserves providers, off-chain trading counterparties, and oracles can each be a single point of failure. The msUSD collapse began with a lack of transparency regarding the off-chain reserves and removal of one dependency — the verification relationship.

Lending vaults carry the risk of their collateral. Allocating to a vault means taking on exposure to every asset the vault accepts as collateral. A thorough assessment requires understanding not just the vault’s own parameters but the instruments behind the collateral and their underlying strategies.

Off-chain strategies need on-chain verification. Assets backed by off-chain activities - trading books, private credit portfolios, insurance reserves - require continuous, independent verification. Without it, investors are relying on the issuer’s word rather than evidence. The right alternative is regulated structure (RWAs): tokenized funds operating under established financial regulation, with proof of reserves from credible independent verifiers. Noon’s backing by Fasanara Capital’s regulated private credit funds, verified through Accountable, is a concrete example.

Allocation platforms that take this seriously are already drawing the relevant distinctions. Nook screens every vault it lists against the full collateral dependency chain. None of the vaults currently on Nook carry exposure to synthetic or strategy-based yield stablecoins.

Closing Thoughts

The msUSD collapse is unlikely to be the last stress event for yield-bearing stablecoins. As the sector grows beyond its current $11 billion market size, investors will increasingly differentiate products not by their headline APY, but by the quality of the underlying strategy, the transparency of the reserves, and the robustness of the verification infrastructure.

The reaction of Morpho’s curators illustrates this shift. Rather than abandoning yield-generating assets altogether, they have moved towards tokenized private credit. These assets are not risk-free, but their underlying cash flows rooted in regulated financial instruments brought on-chain.

The lesson is not that yield-bearing stablecoins are “bad” or that tokenized private credit is inherently “safe.” Some yield-bearing stablecoins resemble conservative money market funds, while others look much closer to actively managed hedge fund strategies. Likewise, the risk profile of tokenized RWAs depends entirely on the quality of the underlying assets and issuers.

There is no universal definition of a “safe” yield-bearing dollar. The only reliable rule is to understand where the yield comes from, who manages the risk, and what happens when markets come under stress. As always in DeFi, due diligence matters more than headline returns.

Over $10 billion has been deposited into curated lending vaults on Morpho. Vault aggregators list thousands of options.

Many looks nearly identical: denominated in stablecoins and advertising yields from 1% to 12% and beyond. Yet the differences between them are often hidden - buried in collateral choices, concentration limits, and risk parameters that the APY number alone does not reveal.

This is why Nook, the allocator platform, lists fewer than ten vaults. We include only those where the risks taken to generate yield are proportionate to the expected return. The difference between a vault we list and one we do not originates not just from the APY itself, but from the strategy the vault executes and the risks taken to generate that yield.

While investors typically view a vault as a product, the most important component is the curator team behind it. The curator is the team that designs the investment strategy, determines the acceptable level of risk, and continuously manages the vault composition. A lending vault may generate yield by lending USDC against ETH, BTC, tokenized Treasury bills, or other digital assets. The vault’s strategy and its curator are the two most important variables in DeFi vault investing.

In this post, we explain how to evaluate vault strategies and the curators responsible for managing them.

A Vault Is Only as Good as the Curator Behind Its Strategy

A vault functions like a simple product: lenders deposit capital and earn yield. Behind the scenes, however, it operates an automated strategy to allocate capital across lending markets. Two vaults can be built on the same protocol, accept the same stablecoin, and display the same APY while exposing lenders to very different risk. These risks stem mostly from the market conditions, but can be mitigated with the governance processes set up by the curators.

Examples of strategies: lend USDC against ETH and BTC, lend against tokenized Treasury bills, lend against high-yield digital assets, or a combination with defined allocation limits per market. The strategy determines both the expected return, its sustainability, liquidity profile and the risks involved. The curator is the team that designs, executes and adjusts this strategy.

Consider a lender depositing $10,000 into a vault displaying a 7% APY. Based on that figure, one may expect to earn $700 over the next year. In DeFi, rates change continuously - a vault paying 7% today may pay only 2% next month if borrowing demand declines (the displayed APY reflects the average from the last seven days, not a guaranteed forward rate). In such scenario, a good curator would re-allocate vault capital from the 2% market to market with higher yield within the the vault risk profile. Consequently, the actual return on a $10,000 investment may not differ significantly from the expected $700.

How Your USDC Generates Yield

When you deposit USDC into a vault, the capital flows into individual lending markets according to the vault’s strategy:

Each lending market on Morpho has different interest rate, determined by supply and demand. A USDC-ETH market might offer 4%, USDC-cbBTC 4.2%, and a market backed by higher-yield collateral 6.5%. The vault allocates across these markets according to the curator’s strategy and the limits they have set - for example, no more than $10M into any single market. On top of these allocations, curators maintain ca 10% liquidity buffer for lenders withdrawals.

What Curators Control, and What They Don’t

A curator does not approve individual loans, but set the rules and conditions (e.g. which collateral types are accepted, at what loan-to-value ratios) It is the lending protocol that enforces those rules automatically and provides loans to borrowers. Any borrower who meets the on-chain criteria can borrow. The curator designs and manages the lending policy; the smart contract executes it.

In practice, a curator’s job is to move capital between lending markets and update allocation limits. When a market has become too concentrated or a collateral asset’s liquidity has deteriorated, curators reallocate capital, adjust supply caps, or update the allowlist. What they cannot do is unwind a loan that is already open - once a borrower has posted collateral and borrow capital, that position remains until repayment or liquidation. The curator’s influence is upstream, before capital enters a market, which is exactly why the upfront evaluation matters as much as the ongoing monitoring. What is more, under any circumstances, the curator does not have the technical possibility to withdraw the lender’s capital from the vault.

Two of the prime vaults available through Nook illustrate what a conservative allocation looks like in practice:

Both vaults concentrate most of their allocation in BTC or ETH markets. The APY of 4.41% reflects the conservative collateral choice. Wrapped Bitcoin or ETH, and its liquid staking tokens, are the most liquid assets in DeFi.

Now let’s compare high-yield vaults of 7%+ instead.

Where Does the Vault Yield Come From?

The reasons why some vaults pay 7%, or more, while others pay just 4.4%, typically come from one or more of the following:

• Credit Risk - lending against digital assets with lower liquidity or higher volatility yields a higher premium, because the default risk

• Liquidity Risk - lower liquidity buffer to instant withdrawals means more capital can be borrowed, earning interest

• Concentration - allocating heavily into a single high-yield market increases returns while reducing diversification

• Temporary Incentives - new protocols sometimes subsidize yields with token rewards that eventually end

Higher APY is rarely free. Understanding the source of a vault’s yield is the first step toward evaluating whether the APY is worth the risk.

The Same APY Can Hide Very Different Risks:
The Three Curator’s Decisions That Define a Vault

Consider two lending vaults, both on Morpho Base, USDC-denominated, and both presenting 7% APY. The first is Steakhouse High Yield, which generates yield by lending against Coinbase-wrapped tokens - cbXRP, cbSOL, cbADA, and cbDOGE - digital assets with real market presence but materially lower liquidity than BTC or ETH. The second is a pure APY-chasing vault that uses automated bots to rotate capital into market offers the highest rate at any given moment.

Although the difference in vault yields is modest, the vaults’ risk profiles are very different. The following factors explain why: collateral, quality, concentration, and utilization.

1. Collateral Quality

The most important decision a curator makes is which digital assets accept as collateral in a vault. ETH and wrapped Bitcoin are large, liquid, and well-understood tokens, a sharp price drop still allows liquidation engines to function and recover the loan before lenders are exposed. Long-tail tokens and yield-bearing assets with limited liquidity are harder to liquidate quickly when prices move against borrowers.

The APY-chasing approach makes this risk concrete. When automated bots rotate capital into whatever token market pays the most today, they will inevitably allocate into assets that offer high rates precisely because they carry elevated risk. During the USR stablecoin hack in early 2026, its lending markets were offering unusually high rates. Bots from yield-optimizing vaults began allocating into them. After USR crashed 97% - from $1.00 to $0.025 - following an exploit, those vaults started publishing post-mortems. The curators who had reviewed USR’s governance structure before allocating had flagged the risk and avoided bad debt. The ones relying on automated APY rotation had not.

2. Market Concentration

A well-managed vault spreads exposure across multiple lending markets with no single market dominating the vault. When one market represents 90% or more of a vault’s capital, the vault is effectively a single-market bet - a sharp deterioration in that market’s collateral, or a sudden exit by its borrowers, can imapct the majority of the vault capital at once. A diversified vault, where no market exceeds 30–40% of total exposure, absorbs individual market stress without systemic impact.

Pure APY-chasing strategies tend toward concentration by design: the bot allocates heavily into whichever market currently pays the most, regardless of how its risk profile compares to others. When conditions in that market change, the vault has limited margin to absorb the shift.

3. Utilization

Utilization is a two-edged sword. Higher utilization means more of the vault’s capital is actively earning - which is what drives the yield. Lower utilization means more capital is sitting idle, earning less, but available for immediate withdrawal.

When a lending vault’s utilization is very high, most of the deposited capital is out on loan and not immediately available for withdrawal.

A vault at 95% utilization resembles a bank that has lent out almost all of its deposits - everything works smoothly until many depositors want their money back at the same time. A vault with $100M in deposits at 95% utilization has approximately $5M in free liquidity.

If $20M in withdrawal requests arrive during a period of market stress -- precisely the moment when depositors are most likely to want their capital - the vault cannot fulfill them until borrowers repay. A vault at 75% utilization has $25M available immediately.

A well-constructed interest rate curve manages this balance mechanically. As utilization climbs above a target threshold - typically around 90% - the borrowing rate increases steeply, incentivizing repayment and driving utilization back down before a crunch develops. At Nook, we do not list vaults where utilization is routinely elevated to mitigate the liquidity risk.

The Curators Behind Nook’s Vaults

The most reliable way to evaluate a curator is not their methodology, but their behavior during the market stress. A curator worth trusting evaluates collateral from economic, technical, and governance perspectives. They maintain diversified exposure with explicit limits on concentration in any single market.

A small number of professional teams have built that track record. Steakhouse Financial and Gauntlet are two of the most established, managing $1.5bnand $0.9bn in vault TVL across Morpho and other protocols,. respectively.. Both curators have operated through significant market stress events, published their risk parameters openly, and maintained records that are auditable on-chain. [1] Their presence on the Nook platform reflects demonstrated behavior, not just stated methodology.

“Users come first. Everything else follows. We optimize for solvency and liquidity. In a repo market like Morpho, a lender should never lose principal and should be able to exit freely. Optimizing for risk-adjusted returns is a downstream effect of that. Our objective is not to maximize APY. Our objective is to maximize risk-adjusted returns for depositors.”

- Hannes Detlefsen, Steakhouse Financial

Nook does not manage vaults. Our role is to evaluate whether a curator is executing their stated strategy responsibly, and consequently, the presented vault APY is sustainable and worth the underlying risk.

• Strategy design. How is yield generated? What collateral backs the loans? What are the curator’s governance processes and infrastrucutre?

• Curator track record. Has the team operated through significant market stress event with documented outcomes?

• Collateral quality. Does every accepted collateral type pass review on liquidity, oracle design, and or bridge security architecture?

• Concentration limits. No single market above 50% of vault exposure.

• Utilization design. Is there a rate curve that corrects utilization above 90%?

The goal is not the highest APY, but the highest risk-adjusted, sustainable return.

Closing Thoughts

Most investors compare APYs. Professional investors compare strategies. Nook evaluates whether the curator is executing that strategy responsibly. Two vaults can display the same 7% APY while exposing investors to very different risks.

The presented vault APY is just the history from the last seven days. The vault strategy and the curator determine what happens over the next twelve months.

DeFi offers real yield opportunities, but capturing them requires understanding both the drives and risks involved. At Nook, we are partnering with top curators, selecting only the vaults where the risk profile is transparent and the track record is real.

Selecting a vault is, in practice, selecting a risk management team. The vault’s APY is a snapshot of 7-day performance. The curator’s decisions determine whether this APY is sustainable.

Over the past year, ONyc grew from $11 million to $167 million in TVL - a more than 10x increase in under twelve months. The obvious explanation would be yield. The real explanation is distribution, and the design decisions that made distribution possible.

ONyc demonstrates what happens when an RWA is built not only for issuance, but for secondary trading, lending market integration, and DeFi composability from the ground up. The lessons are worth examining, because they apply to any issuer trying to move from a tokenized product to a DeFi-adopted digital asset.

What Is Tokenized Reinsurance?

Reinsurance is often described as insurance for insurance companies. Rather than insuring individuals or businesses directly, reinsurers provide capital to insurance companies and absorb part of their risk in exchange for premiums. It is a large, mature asset class that has historically been accessible only to large institutional investors - due to high minimum tickets, long lockups, and significant operational complexity.

Tokenization changes the access equation. ONyc packages reinsurance exposure into an on-chain asset that can be held, traded, borrowed against, and composed across DeFi protocols. For investors, this offers exposure to a yield source that is largely uncorrelated with crypto markets - reinsurance premiums are driven by insurance cycles and catastrophe risk, not token prices. For DeFi, it introduces a new category of productive collateral backed by real economic activity rather than crypto-native speculation.

Lesson 1: Yield Must Accrue On-Chain

Many tokenized assets still distribute yield through off-chain coupon payments - a quarterly or monthly transfer that requires investors to claim manually, often through a separate process that involves off-chain settlement. This creates friction at every level. For example, DeFi vaults cannot compound yield that does not exist on-chain, nor can lending protocols factor such yield.

ONyc takes the approach that has proven most compatible with DeFi: yield accrues directly into the token value. There are no coupon distributions, no manual claims, no off-chain settlement processes. The token price increases as premiums are earned, in the same way that a liquid staking token appreciates as staking rewards accumulate. This design makes ONyc legible to DeFi ecosystem - vaults, lending protocols, and other liquidity pools can all work with it without custom integrations or off-chain data feeds.

The lesson for issuers is that yield accrual mechanics are not an accounting detail but a distribution decision.

Lesson 2: Permissionless Transfers Are a Prerequisite for Composability

Many tokenized assets carry transfer restrictions that made sense at issuance — KYC requirements, whitelist controls, jurisdictional limitations — but that significantly reduce their usefulness once they are on-chain. A token that cannot move freely between wallets and protocols cannot be listed on a DEX, deposited into a lending vault, or included in a portfolio strategy. It exists on-chain in name only.

ONyc can move freely between users and protocols. This single property unlocks the entire stack of DeFi integrations that drove its growth — DEX liquidity pools, Kamino lending vaults, cross-chain vault infrastructure, and Nook’s discovery and allocation layer. Composability is not built; it is enabled by the absence of restrictions that would otherwise prevent it.

Lesson 3: Secondary Market Converts an Investment Product into a Financial Asset

Most tokenized RWAs are structured as investment products: subscribe/redeem at the primary market, wait the required period. This is workable for institutional investors with long time horizons and tolerance for operational friction. It is not workable for the DeFi capital base, which expects the ability to enter and exit positions continuously, adjust leverage in real time, and integrate assets into dynamic strategies.

ONyc invested deliberately in secondary market liquidity. The token is actively traded on leading Solana DEXs, including Orca and Raydium, with deep enough liquidity to allow meaningful position sizing without significant price impact. This creates continuous price discovery - the market reflects actual supply and demand rather than relying entirely on NAV calculations - and enables the kind of active position management that DeFi users expect.

Given the regular price updates and specific token price trajectory, marketing making of secondary liquidity can be almost fully automated with a solution like Arrakis, for a fraction of the costs of professional market makers.

Lesson 4: Lending Integration Creates a Demand Flywheel

One of the most important growth driver for ONyc has been its integration with Kamino, Solana’s leading lending protocol. Today, approximately $100 million of ONyc - nearly 60% of its circulating supply - is deposited in Kamino vaults as collateral.

The mechanics of this flywheel are as follows:

• An investor buys ONyc on the Orca (secondary market) and deposits it as collateral on Kamino.

• Against that collateral, they borrow stablecoins - at current rates, around 6% annualised.

• They then redeploy that capital, either back into ONyc or into other yield-generating strategies.

• At current ONyc yields of approximately 12%, the spread between yield earned and borrowing cost is positive, creating an incentive for leveraged exposure that drives additional buying pressure on the token (on the secondary market).

If you’re interested in how the liquidity flywheel works in detail, check out my previous blogs on this topic.

Distribution Is Becoming a New Layer

As RWAs become integrated into DeFi, a new category of infrastructure is emerging around vault discovery, allocation, and access.

Platforms such as Nook allow users to compare yield opportunities across vaults and strategies, making it easier for capital to find productive, sustainable, and secure on-chain assets.

For RWA issuers, this creates another distribution channel that goes beyond exchanges and lending markets.

Lesson 5: Distribution Is More Important Than Issuance

Most RWA projects spend the majority of their early energy on the issuance side — legal structure, regulatory classification, custody, KYC, token mechanics. These are genuinely difficult problems, and solving them is a prerequisite for everything else. But they are not what drives adoption.

Successful DeFi-native RWAs require more than legal structures and token issuance.

ONyc’s growth from $11 million to $167 million was not driven by better legal structuring or more sophisticated tokenization. It was driven by deliberate investment in the distribution layer:

• secondary liquidity on Orca and Raydium,

• lending integration on Kamino,

• a positive carry structure that incentivises leveraged demand

For RWA issuers, the key question has shifted. The question used to be how to put an asset on-chain. The infrastructure to do that now exists and is well-understood. The question now is why a DeFi participant should hold the asset rather than any of the alternatives competing for the same capital - and how to build the distribution infrastructure that makes the answer to that question obvious.

The Next Stage: Cross-Chain Distribution

The RockawayX vault launch on Accountable represents a next step in ONyc's evolution. Rather than remaining within the Solana ecosystem, the asset is now being distributed to Ethereum users through dedicated vault - expanding the addressable investor base without requiring Ethereum-native users to bridge or switch ecosystems.

The new OnRe vault is set up via the Accountable protocol that used zk proof to verify that RockawayX really invested the vault capital in OnRe products and the vault reserves balance its value.

Closing Thoughts: What ONyc Got Right

ONyc’s growth is a case study in the difference between tokenization and adoption. The asset was not the first tokenized reinsurance product, and its yield is not uniquely superior to alternatives. What distinguished it was execution across the full stack of DeFi ecosystem: on-chain yield accrual, permissionless transferability, secondary market, lending market integration with a positive carry structure.

As a result, 60% of all ONyc’s tokens are today deposited in Kamino for USDC lending, retail users trade permissionlessly 24/7 at Orace and most importantly market capitalization grew 10x in less than one year.

The $11 million to $167 million trajectory is not a story about a great asset finding its audience. It is a story about distribution infrastructure being built deliberately, layer by layer, until the demand flywheel becomes self-sustaining.

For any private credit, insurance, or structured finance issuer thinking about on-chain distribution, that is the template worth studying.

In 1976, Vanguard launched the first index fund available to retail investors. The premise was straightforward: democratise access to diversified equity investing. Before Vanguard, investors had two options. They could select individual stocks themselves - a process that required a brokerage account, significant capital, and the ability to research hundreds of companies. Or they could pay an actively managed mutual fund to do it for them, at annual fees of 1–2%, with most of those funds still underperforming the market.

For the vast majority of people, meaningful participation in equity markets was either inaccessible or prohibitively expensive. Vanguard changed that by indexing the entire market at a fraction of the cost - and making diversified investing something anyone could do.

Today, ETFs and mutual funds hold more than $30 trillion globally.

DeFi in 2026 presents the same structural challenge at a different scale. With thousands of vaults across Morpho, Aave, Euler, and Spark - each backed by different digital assets, each with different risk parameters - evaluating the opportunity requires the kind of continuous monitoring and expertise that most investors neither have nor need to develop. The yield, however, is real: conservative stablecoin vaults currently generate 5–7% APY and are available Nook, compared to 0.04% in a Bank of America savings account.

That is 10 to 20 times the return on traditional cash savings - a difference that compounds significantly over time.

A DeFi vault is the answer to the digital asset complexity. It pools capital from investors and deploys it according to a defined lending strategy. The vault curator handles allocation, monitoring, and rebalancing on behalf of lenders. Over $10B in assets is now deposited in curated lending vaults on Morpho alone. [1] That capital was allocated to DeFi vaults because the yield difference with banks, measured in actual dollars over time, is too large to ignore.

What Exactly Is a Vault?

A vault is a smart contract - a computer program operating on the blockchain - that pools capital from many investors and deploys it according to a predefined strategy. The mechanics of Morpho vaults are straightforward:

• An investor deposits USDC into the vault and receives vault shares representing their ownership.

• The vault allocates that USDC across one or more lending markets according to its strategy.

• Interest earned by those markets accrues back into the vault.

• The investor can withdraw USDC plus earned yield at any time.

Lending markets in DeFi do not work like a peer-to-peer loan, where one lender is matched to one borrower. There is no system waiting to pair your $10,000 deposit with a single borrower who needs exactly $10,000.

Instead, all depositors contribute to a shared liquidity pool, from which borrowers draw the capital. Consequently, the risk of borrower default is mitigated and spread across all pool.

Interest accrues real-time and is distributed proportionally across all lenders. The interset rate is based on how much of the pool is currently borrowed:

• When utilization is high - more of the pool is borrowed - interest rates rise.

• When it falls, rates decline.

The system is entirely automated, governed by the smart contract rather than by any matching engine or counterparty negotiation.

For example, the Steakhouse Prime USDC vault on Morpho - one of the vaults available through Nook - allocates $330mn worth of USDC for loans across multiple collaterals: ETH, BTC, and other digital assets. A lender contributes capital once to a vault and earn 3.8% interest rate. The vault curator continuously handles allocation, monitoring, and risk parametrization.

Your Assets, Your Control

The important distinction from traditional banking is that the well-structured DeFi vaults are non-custodial. In a bank or a traditional fund, you hand your assets to an institution. You trust that institution to hold them, report accurately, and return when ask.

In a non-custodial vault, the assets remain yours at all times. The vault is a smart contract - a computer program,, published on the blockchain.

When you deposit your stablecoins, the vault contract records your ownership share. When you withdraw, the contract releases your funds directly to your wallet. There is no intermediary controlling your assets.

This structural difference means that even if the company operating the vault interface shuts down, your assets remain accessible through the underlying protocol. The rules enforcing your ownership are written in code, not in a terms-of-service document.

The Three Main Types of Vaults

DeFi offers various vault types, each with different risks and rewards

Lending Vaults

The most common category, and generally the lowest-risk. These vaults lend stablecoins such as USDC to borrowers who post overcollateralized collateral.

Examples available through Nook: the Steakhouse USDC vault and Gauntlet USDC Core vault, both on Morpho. Typical APY range: 4–7%.

The mechanism protecting lenders is overcollateralization - borrowers must post more collateral than they borrow, and positions are automatically liquidated if that buffer is breached. As we covered in our first post, Your Bank Is Keeping the Yield, this is what allows DeFi lending to operate without traditional credit underwriting. In most market conditions, it effectively protects lenders from borrower default.

DEX Liquidity Vaults

These vaults provide liquidity to decentralized trading markets rather than lending markets. When traders swap assets on protocols like Uniswap or Aerodrome, they draw on capital provided by these vaults, and liquidity providers earn a share of the trading fees.

Returns can appear attractive, but this category carries a risk that is easy to miss: impermanent loss. When the prices of the deposited assets diverge significantly, the vault’s actual returns can be lower than they would have been if the assets had been held. We return to this in the section on APY traps below.

Leverage Yield Vaults

These vaults employ more aggressive strategies: leveraged positions, or stacking multiple yield sources simultaneously.

A leveraged vault might borrow USDC, deposit it into a lending market on Morpho or Euler, borrow again against those deposit receipts, and repeat. Each loop amplifies both the yield and the exposure to adverse conditions. APYs can reach double digits. So can the losses when things move in the wrong direction.

Three Types of Vaults. Very Different Risk Profiles.

Most investors instinctively select the vault with the highest advertised yield. This is often the wrong decision, and sometimes a costly one.

Consider a simple example. An investor with $10,000 offered the following three options:

Vault B is the trap that catches the most investors. DeFi aggregators display the gross fee APY - sometimes 15%, 17%, or higher - without accounting for impermanent loss. The net return, after price divergence is factored in, can easily be negative. An investor who deposited $10,000 expecting $1,700 in annual income could instead finish the year with $9,700.

The published APY reflects what a vault pays when every assumption holds. It says nothing about what happens when they do not.

The Biggest Mistake: Chasing APY

DeFi currently hosts over 1000 active curated vaults across various categories. They each have different levels of risk, and the advertised APY rarely reflects those differences.

Out of three vault categories in DeFi, Nook offers only one: lending vaults. This is a deliberate choice, as lending vaults offer attractive, stablecoin-denominated returns with the lowest tail risk of any vault category. Rules governing lending vaults are published on-chain and auditable by anyone. The higher advertised yields in liquidity provision and yield enhancement vaults come with market risks - impermanent loss, leverage exposure - that are easy for investors to underestimate and hard to mitigate.

The Case for Starting Early: Five Years of Compounding

The yield difference between a savings account and a well-managed vault may seem abstract when measured in one year. Yet across five years, the difference becomes significant.

The gap between a savings account and a conservative DeFi lending vault - $2,865 over five years on a $10,000 investment - is significant. It is the difference between a savings account that is barely outrunning inflation and one that meaningfully compounds over time.

Nook provides access to a curated selection of lending vaults - chosen for conservative risk profiles, transparent parameters, and consistent stablecoin-denominated returns. The compounding in the table above is not theoretical: Nook customers have been earning at these rates since the platform launched in June 2025, and have collectively processed over $1 billion in transactions across those vaults to date.

Closing Thoughts

When Vanguard launched the first index fund in 1976, it did not require investors to become stock analysts. It gave them access to a professionally managed, diversified portfolio. ETFs now hold more than $30 trillion globally.

DeFi vaults are following the same trajectory. There are over 1’000 vaults available for investors, falling into one of three categories: lending, liquidity provisions or leverage. Nook offers only one type - lending vaults. This is a deliberate choice, as only these vaults offer sustainable, stablecoin-denominated returns. The higher yields advertised by other categories come with hidden risks that are not reflected in the headline APY.

Over $10B is allocated to leading vaults on Morpho today. That capital did not flow there because investors understood every technical detail of how each market operates. It flowed there because investors found vault strategies they trusted.

The question worth asking before depositing is not: which vault has the highest APY? The better question is: how sustainable this yield is, and who is managing the risk behind it?

Thanks for your time,

[1] Morpho TVL: Morpho Protocol TVL data via DeFiLlama; total protocol TVL crossing $10B by April 2026.

By early 2025, the total value of tokenized assets on public blockchains had surpassed $27 billion, with private credit accounting for a growing share of that figure.

Fasanara Capital (mF-One, mGlobal), Maple Finance (syrupUSDC/USDT), FalconX (AA_FalconXUSDC), Apollo (ACRED), Wintermute-backed Wildcat (v-wmtUSDC) and other structured-credit funds have all made meaningful on-chain debuts. The list is longer every quarter, and the pace is accelerating. What this wave of issuance demonstrates, above all, is that the legal, technical, and operational groundwork for bringing real-world credit into DeFi has been laid.

In the post, I study the case of Fasanara Capital, a London-headquartered alternative asset manager. Fasanara, launched two tokens: mf-One and mGlobal on the Ethereum blockchain, representing its private credit funds, and integrated them with the Morpho, leading DeFi lending protocol.

Three Reasons to Bring Your Token to DeFi

Tokenization gets assets on-chain. Decentralized Finance (DeFi) enables them to function as on-chain financial instruments and drives investor demand.

1. DeFi as a Credit Layer for Your Investors

The core benefit — and the one that most directly changes the economics for issuers and investors alike — is what DeFi lending does for existing investors. When a tokenized credit token is listed as collateral on a DeFi protocol like Morpho or Euler, lenders deposit stablecoins into curated vaults, and institutional investors in RWA token can borrow against their position.

An investor who wants $1 million of exposure to the credit strategy no longer needs $1 million of capital. With a 50% loan-to-value ratio, $500,000 of their own capital — collateralised by the token — unlocks the rest through a Morpho vault backed by stablecoin liquidity.

Curators like Steakhouse Financial set the risk parameters — LTV ratios, liquidation thresholds, acceptable collateral types — based on rigorous analysis of the underlying asset. The stablecoin liquidity comes from lenders, often institutional, who have chosen to deploy into curated credit vaults because the risk-adjusted yield, e.g. 5-6% on USDC.

Currently, over 33% of all mf-ONE tokens in circulation are deposited into Morpho vaults. These tokens are used as collateral to borrow over $11mn in USDC, which can be used to expand the fund's exposure via leverage.

In this use-case, DeFi acts as the rail — a programmable, transparent, always-on credit market — not a different class of investor. It extends the capital efficiency available to the fund existing investors without changing who those investors are.

2. DeFi as a Distribution Channel

The second benefit is distribution — and the argument here is similar to the case for tokenization itself. Just as putting an asset on-chain removes the operational friction of traditional fund subscriptions, integrating it into DeFi infrastructure removes the distribution friction that limits which investors can practically access it.

On-chain family offices, DAO treasuries, crypto-native hedge funds, and yield-seeking stablecoin holders represent a capital base that is growing rapidly and actively looking for diversified, real-world yield.

Fasanara issued its mf-ONE and mGlobal tokens via Midas, a leading tokenization platform. Any user who has completed KYC can purchase (or redeem) tokens on this primary market. The minimum investment ticket is $150k.

3. Access to Retail Investor

The third benefit is genuine access to the DeFi retail investors — and this is where the story is most forward-looking. These investors are comfortable operating entirely on-chain, they evaluate assets based on on-chain metrics and protocol risk parameters, and they tend to move faster than traditional allocators once an asset has earned credibility in DeFi contexts.

Reaching this category of investor requires more than tokenization and integration with DeFi lending — it requires secondary liquidity.

The Role of Secondary Trading in Bringing New Capital On-Chain

Primary subscriptions and redemptions are sufficient for institutional investors, but create frictions for retail investors (min. investment ticket of 150k, 30 day redemptions). For DeFi-native capital, secondary trading is what creates genuine accessibility.

Consider the practical difference. A DeFi user who wants exposure to tokenized private credit through a primary market needs to complete a subscription process, wait for settlement, and then hold until they choose to redeem — again through the primary market, again with a waiting period. A user who can buy the same token on a secondary market buys it in the same transaction as any other on-chain asset, holds it for as long as they want, and sells whenever they choose.

Secondary trading also changes the economics for leveraged strategies. A user who borrows against a tokenized credit position on Morpho and then wants to adjust their leverage ratio needs to buy or sell the underlying asset. If that can only happen through the primary market on a T+2 or T+3 basis, active management becomes impractical. If it can happen in seconds on-chain, the full range of DeFi leverage strategies opens up — and with it, a category of users who are willing to pay for that capital efficiency in the form of borrowing costs and trading fees that ultimately benefit the protocol and the asset’s liquidity providers.

Yield Distribution Through a Yield Stablecoin - Noon

One of the more interesting design choices in the current RWA wave is Noon’s approach of packaging credit yield inside a yield stablecoin.

Rather than issuing a token that represents a share of a credit fund — which users then need to hold, post as collateral, or trade as a separate asset — Noon embeds the yield directly into a dollar-denominated token that behaves like a stablecoin in DeFi contexts but accrues private credit returns to the holder.

This design makes sense for a specific reason. Such yield stablecoins are listed on every DEX (e.g., Uniswap), creating a liquid secondary market for the broad retail investor base.

What Makes a Tokenized Credit Asset Ready for DeFi

Not all tokenized credit products are equally well-suited to DeFi integration, and the differences tend to come down to a handful of design choices that issuers make at the outset.

Evergreen structure. The most DeFi-compatible products have no fixed maturity, or use rolling maturities that smooth out redemption events over time. Lending protocols set risk parameters around collateral assets, and a token whose value could cliff at a known future date creates complications that most protocol risk teams will simply avoid. An evergreen credit fund, by contrast, can be modelled much like any other continuously-priced asset.

Yield accrual mechanics. A token whose price increases daily as interest accumulates — rather than distributing coupons manually — is intuitive for DeFi users and integrates naturally with vault strategies that track net asset value over time. This is how most successful RWA and yield-bearing tokens in DeFi work, from liquid staking tokens to money-market shares, and private credit products that follow the same pattern benefit from the same composability.

On-chain NAV and transferability. Transparent, on-chain NAV calculation with price feeds updated frequently enough for lending markets to use is a prerequisite rather than a differentiator at this point.

Open Challenge: Liquidations

One requirement that deserves particular attention is liquidation viability. A lending protocol can only accept an asset as collateral if it is confident it can sell (liquidate) that collateral cleanly in a stress scenario.

For tokenized credit assets that trade only through primary markets, that confidence is hard to establish — redemption queues do not clear fast enough for a liquidation bot to act on. Solutions such as Symbiotic Fast Lane or Grove Basin aim to address these risks for DeFi lenders.

This is also where independent due diligence by DeFi lenders becomes essential: conducting an own review of curator risk parameters, collateral quality, and available liquidity before any capital is deployed into the lending vault.

Allocation platforms, such as Nook, verify that what the curator has set up in practice matches what it says on paper: that liquidation mechanisms are functional, that there is no concentration risk that could create a liquidity crunch, and that the vault has no structural exposure to bad debt.

Closing Thoughts

Fasanara’s mf-ONE is one of the clearest proofs of successful DeFi integration that the tokenized credit market has produced. Fasanara did three things that most issuers have not yet done together:

• First, it launched a token on a public blockchain — Ethereum — giving its private credit fund on-chain representation that could interact with DeFi infrastructure.

• Second, it integrated that token with Morpho, enabling investors to borrow stablecoins against their mF-ONE holdings. The results speak for themselves: over 33% of all mF-ONE tokens are now deposited into Morpho vaults as collateral, and that integration contributed to a 20% increase in the fund’s market cap.

• Third, via Noon’s yield stablecoin USN, it extended access to retail investors who want private credit exposure in a dollar-denominated, liquid form - without the minimum ticket and redemption constraints of the primary market.

Maple Finance’s syrupUSDC shows what this approach looks like at scale: a $1.8 billion market cap, a fully liquid secondary market on Uniswap, and over $500 million in Morpho collateral. That is the trajectory mF-ONE and mGlobal are on once fully liquid secondary markets are open.

The broader lesson is not specific to either issuer. Any private credit manager who can structure an evergreen, yield-accruing, on-chain transferable token and meet the collateral requirements of a lending protocol like Morpho or Euler can access the same dynamic. The credit line is the product. The token is how you deliver it.

Background: The Vault and Its Assets

The vault routes depositor USDC into two Euler lending markets, each backed by a Securitize-issued tokenized asset:

• VBILL, VanEck’s tokenized short-duration Treasury fund — investing in cash, US T-bills, and repurchase agreements, with State Street as custodian.

  • As of May 2026, VBILL holds approximately $61M in AUM, having launched in May 2025 as VanEck’s first tokenized fund.

• STAC, the Securitize-BNY tokenized CLO fund, which invests in a diversified portfolio of US AAA-rated collateralized loan obligations, with BNY serving as custodian and sub-adviser.

  • STAC launched with a $100M anchor allocation from institutional credit protocol Grove and is sub-advised by a BNY team.

When utilization in these markets is low, the vault also allocates to the RLUSD market — Ripple’s USD-backed stablecoin — which also acts as an instant-redemption liquidity buffer

The vault charges no performance or management fee, but 5% curator fee on borrow interest at the KPK-curated markets.

🏦 1. Treasury Collateral Changes the Risk Model

Most DeFi lending was designed around assets that trade 24/7 on liquid secondary markets (DEXs): ETH, BTC, liquid staking tokens. Especially, liquidation mechanisms were all built for assets where price discovery is continuous and exit is always available.

Treasury-backed assets behave fundamentally differently. VBILL is a short-duration fund holding T-bills and repos. Large price dislocations are unlikely, which means liquidation events should be rare in normal market conditions.

But it shifts risk away from volatility and toward a different set of concerns:

• liquidity risk (can the asset be redeemed fast enough to settle a DeFi loan?),

• redemption risk (what are the mechanics and timing of the primary market process?),

• operational risk (oracles, KYC enforcement, custodian procedures),

• and issuer risk.

KPK’s collateral choices reveal careful thinking about this trade-off. VBILL offers instant liquidity with a minimum investment ticket of $1,000 and daily redemptions. STAC has a $100,000 minimum ticket but also offers daily redemptions. These are among the most liquid RWA products available in the RWA ecosystem today.

By contrast, many RWA markets on Morpho accept assets with 30-day subscription and redemption windows and minimum tickets of $150,000 or more. Those products create lending markets that DeFi’s liquidation infrastructure was not designed to handle. Solutions like Symbiotic try to tackle these challenges.

🏗️ 2. A Lending Market without a Secondary Market

The standard DeFi set-up of each crypto asset has three components:

• token issuance,

• a secondary market (a DEX where anyone can trade the token),

• and lending markets.

This is how ETH, BTC, liquid staking derivatives, and stablecoins all work. The secondary market is what gives DeFi’s liquidation system teeth: when collateral needs to be seized and sold, there is always a buyer somewhere on-chain.

RWAs break that architecture. Setting up a deep secondary market for a tokenized Treasury fund is difficult. As a result, the USDC Prime RWA vault connects the primary market directly to the lending protocol:

Securitize → VBILL / STAC → Euler

This is the same architecture used by Fasanara’s mF-ONE product and FalconX’s credit vault on Morpho (they scaled from zero to $190M in 12 weeks and has become a reference design for institutional RWA lending).

Initiatives like UnWind (Keyring), 3F, aim to address some gaps, offering secondary liquidity for RWA tokens for efficient looping. These are early-stage, but their emergence reflects how seriously the market is taking the secondary liquidity problem.

💸 3. The Interest-rate Model is Borrower-friendly

In DeFi lending, interest rates are not set by any policy committee. They are encoded in smart contracts that respond to utilization: when most of the liquidity in a market is borrowed, rates rise to attract more deposits and slow borrowing; when utilization is low, rates fall.

The specific shape of that curve - how steeply rates rise, where the kink sits, what the ceiling looks like - is configured by curators and encodes a particular view of who the market is designed to serve.

The KPK vault’s rate curve is notable for its ceiling. VBILL currently yields roughly 4–5% as a cash-equivalent Treasury instrument. The vault’s borrow rate on USDC is set to remain below that level — in the 3.5–4% range — which creates a structurally compelling proposition for borrowers.

• A VBILL holder can deposit their Treasury tokens as collateral, borrow USDC at below-VBILL-yield rates, and deploy that USDC elsewhere, while retaining their Treasury exposure. The net borrowing cost is negative relative to the collateral’s own yield.

That is a meaningful structural advantage over, borrowing against ETH — where the collateral yield is uncertain and the borrow rate can spike well above it during periods of high demand.

📈 4. The Real Test is Borrowing Demand

Tokenization solves a supply problem. It makes previously illiquid assets - Treasury bills, CLO tranches, private credit - available as on-chain collateral. What it does not automatically create is a borrower base.

Many RWA lending integrations have launched on the implicit assumption that supply-side onboarding is the hard part and that demand will follow. The Morpho RWA data offers a useful reality check: despite $10B+ in overall Morpho TVL, RWA collateral-backed loans account for only around $111M in active borrowing across all Morpho markets as of early 2026 — a fraction of the collateral deposited. The utilization gap between crypto-native and RWA markets is large.

The credible borrower base for a VBILL-collateralized USDC market is real: hedge funds seeking leverage on Treasury exposure, stablecoin arbitrageurs, institutions managing short-term liquidity needs, and DeFi participants running basis trades.

The vault’s borrower-friendly rate curve is the primary lever for stimulating this demand. Whether it is sufficient to drive meaningful utilization will be the most important metric to watch in the first six months.

⚔️ 5. Euler is Making a Play for RWA Pending

Most RWA lending integrations launched in 2024 and 2025 chose Morpho. The Fasanara mF-ONE vault, the FalconX credit vault, the Steakhouse-curated institutional vaults — all on Morpho. Morpho’s curator ecosystem, its risk-isolated market structure, and its $10B+ TVL made it the default. KPK chose Euler instead.

Euler V2 holds approximately $890M in TVL on Ethereum as of early 2026, a fraction of Morpho’s scale, but the protocol offers specific features that matter for RWA collateral: per-market risk isolation (a problem in one vault cannot propagate to others), but this solution can also lead to extreme liquidity fragmentation and spikes in APYs for lenders.

The RWA-collateralized vault segment on Euler is currently small - approximately $80M. If tokenized Treasuries and private credit continue growing toward the $100B+ projections for end-2026, we will see which lending protocols captures most of the lending stack. This launch suggests Euler wants to compete for that opportunity.

🚨 6. What Happens During a Liquidity Crunch?

Liquidity crunch is similar to bank run event, when depost withdraws happen slowly, or even are paused. This is one of key factors stress tested by vault allocators such as Nook.

The design of the KPK vault - borrower-friendly rates, primary-market-only liquidity, a 12.5% withdrawal buffer - works well when utilization is moderate and flows are orderly. The interesting question is what happens when it does not.

Imagine a scenario where lenders want USDC back, utilization has risen sharply, and redemptions from VBILL or STAC take 24 hours to settle at the primary market level. -

• In a traditional DeFi market backed by ETH or BTC, the response is simple: borrow rates spike to 20%+, which immediately slows new borrowing and incentivizes repayments.

• In an RWA market with a capped borrow rate, that self-correcting mechanism is muted. The ceiling that makes the vault attractive to borrowers in normal times limits how aggressively the protocol can reprice risk during stress.

  • The RLUSD liquidity buffer provides a first line of defense - instant-redemption stablecoin exposure that can be liquidated without touching the RWA primary market process.

  • Whether 12.5% is sufficient to absorb a realistic redemption shock is a function of vault scale and the correlated behavior of the depositor base: a large institutional depositor exiting cleanly under normal conditions is a different event from a coordinated withdrawal during market stress.

Final Thoughts

The tokenized RWA market has grown nearly 500% in 18 months and is tracking toward $100B by end-2026. As that capital moves on-chain, it will need somewhere to go beyond simple holding. Lending markets are the natural next step.

What makes the KPK vault worth watching is not just the assets - Treasury bills and AAA CLOs are well-understood instruments, but tis the design choices:

• collateral selected for liquidity quality,

• an interest-rate model engineered for carry trades,

• a direct primary-market architecture without DEX intermediation,

• fees charged only on the borrowing rate

Whether the borrower demand materializes, whether the liquidity buffer holds under stress, and whether Euler’s curator ecosystem can match Morpho’s depth are all open questions. The answers will arrive over the next six months and will tell us how institutional RWA lending in DeFi actually works.

Kudos to the KPK team for pushing the space forward. The results will be worth watching.

That last number is what makes the Select vault interesting. The yield premium comes from tokenized RWA, precisely a new collateral type Wintermute has onboarded into Morpho - a wrapped position in its own Wildcat credit market.

Background: what a Morpho vault is, and why RWA issuers want in

Morpho is a permissionless lending protocol with two new DeFi primitives. The first is isolated credit markets - each market pairs exactly one collateral asset with exactly one borrow asset (for example, wstETH / USDC), with its own loan-to-value (LTV), liquidation threshold and oracle. Bad debt in one market is contained inside that market. The second primitive is the vaults that sit on top: a vault accepts USDC deposits from passive lenders and re-allocates that USDC across whitelisted isolated markets according to a set of caps and parameters chosen by the curator.

Curators are the credit officers of DeFi. Gauntlet, Steakhouse, KPK, Galaxy and now Armitage (Wintermute) all sit in this role. The curator decides which collateral types enter the vault, what LTV is acceptable, which oracle is trusted, and how much capital can be deployed against any one collateral.

Tokenised RWAs reach DeFi through exactly this layer. The RWA token is admitted into an isolated market against USDC; the curator sets the parameters; the vault deposits flow into that market when a borrower needs leverage. For a tokenised credit token, this is the most efficient distribution channel into onchain capital - a holder can borrow USDC against the token, recycle the USDC into more of the token, and the issuer gets continuous demand-side flow without minimum-ticket or redemption-window friction.

The vault is also the natural risk container. If the RWA market breaks, the loss is bounded by the cap that the curator set, not socialised across all DeFi.

The two Armitage vaults: same architecture, different risk profiles

Prime is the conservative vault. The accepted collateral list is the standard blue-chip stack: wrapped BTC, wrapped ETH, liquid-staked ETH (wstETH, weETH). This is the same risk profile that Gauntlet, Steakhouse, Galaxy and KPK USDC vaults already offer, which is exactly why Prime yields a similar 3–4.5% - there is no structural reason for it to clear above the peers.

Select starts from the same blue-chip base but explicitly admits additional collateral classes that Prime does not: tokenized RWAs. The first non-blue-chip market Wintermute has onboarded into Select is v-wmtUSDC as collateral against USDC. This intention brings higher-yielding credit exposure into Morpho.

If Wintermute can keep onboarding well-priced credit exposure on the Select side at 6–8% net to the LP, this becomes one of the more interesting curator products on Morpho. If the credit underwriting is wrong, the same structure is what will produce the loss.

RWA in vaults: the four risks to watch

Independent of any specific issuer, the same four risks recur every time an RWA token is admitted as collateral into a vault:

1. Oracle / NAV. Where does the price come from, who publishes it, how often, what happens when it is stale. For a tokenized credit position, there is no organic on-chain price, so the curator has to choose between an independent-published (and calculated) NAV feed, issuer NAV estimations, and a DEX-derived feed - all have failure modes.

2. Liquidation path. When a borrower defaults, can the collateral actually be liquidated within the protocol’s liquidation window. For tokenised credit with weekly or monthly redemption windows, the on-chain liquidation path needs an explicit answer: atomic redemption, RFQ settlement, or a market maker standing behind a quote.

3. Governance. Who issues the collateral, who prices it, who lends against it. If the same entity holds all three roles, the credit decision and the pricing decision can lead to the conflict of interst.

4. Liquidity crunch. How liquid is the credit market underlying the token? Can the tokens be redeemed anytime?

The above checklist is a standard evaluation that any credit committee would apply to a structured-credit warehouse. The RWA category lacks a shared standard, so the same questions get re-asked in every integration.

What an LP should still keep in mind

The v-wmtUSDC collateral inside Select is worth a closer look, because it is structurally novel.

The collateral. v-wmtUSDC is a non-collateralised lending position to Wintermute vault issued on the Wildcat protocol. Lenders deposit USDC; Wintermute borrows against an unsecured position; yield accrues each block at a fixed APR (currently 9.25%).

The honest summary: this is fundamentally a credit decision on Wintermute, framed inside a DeFi-curated wrapper. For an LP who underwrites Wintermute as a credit, the Select vault is a reasonable way to access ~6% net yield with a transparent risk story. For an LP who cannot underwrite Wintermute as a credit, the yield premium is not free; it is the compensation for taking that credit.

If you trust Wintermute, the Select vault is one of the more honestly designed RWA-curator products on Morpho today. If you do not, or if you are an allocator who is required to apply standard separation-of-roles controls, the structural concentration is real and should be priced into how much exposure you size to it.

Closing

The Wintermute Armitage launch is one of the clearest examples to date of where curator-led RWA integration is heading. The structural questions raised here, bespoke oracles, immutable parameters as a substitute for governance, role concentration mitigated by reputation, are the questions every issuer-curator pair will have to answer over the next twelve months.

If you are an issuer, curator, or allocator working through the same trade-offs, this is the layer I work on. I help treasury allocators evaluate vault integrations from the demand side, and I help RWA issuers design curator-ready integrations from the supply side, oracle setup, separation of roles, permissioned secondary architecture, and the risk framework that supports them. Happy to discuss any of the above in more detail.

A recent incident in Aave illustrates how misconfiguration in the oracle triggered large-scale liquidations, even though the protocol operated according to its defined rules. There was no attacker and no exploit.

This type of failure becomes more relevant as DeFi integrates real-world assets (RWAs). DeFi protocols were designed for continuous markets with near real-time pricing. In contrast, RWA tokens introduce constraints such as minimum investment sizes, delayed redemptions, and infrequent NAV updates. This creates a structural mismatch between on-chain markets and the RWA tokens.

To bridge this gap, on-chain market makers play a central role. They align decentralized exchange (DEX) prices with external valuations and ensure sufficient liquidity for trading and liquidations. At the same time, vault curators allocate capital across markets, but their ability to scale depends on reliable pricing and liquidity. As a result, system stability increasingly depends on the interaction between RWA NAV pricing, market makers, and curators.

Background

Vaults and Curators

New lending protocols such as Morpho differ from earlier designs like Aave. They isolate (fragment) liquidity across individual markets defined by collateral pairs. For example, Aave operates one USDC liquidity pool from which all borrowers can borrow USDC (no matter what collateral they post). In contrast, Morpho splits USDC into smaller pools that depend on the collateral. Token pair markets - WETH–USDC or tRWA–USDC, have their own USDC pools (from which borrowers borrow) and risk parameters.

Curators define these parameters (depending on the token pairs) and decide how capital is allocated across these markets. Vaults operate on top of this:

• Vaults accepts capital from liquidity providers (LPs)

• Vaults distribute capital across curated markets.

Vaults act as allocation layers that balance yield and risk, making their performance dependent on both pricing accuracy and market stability.

Oracles and Liquidations

Oracles provide the price feeds used to value collateral and debt. Based on these prices, lending protocols determine whether a position remains sufficiently collateralized.

If the collateral value falls below a threshold, the position is liquidated to prevent bad debt. This mechanism assumes that oracle prices reflect economic reality. When this assumption fails, positions can be liquidated incorrectly, and liquidation cascades can emerge. Oracle reliability is therefore central to protocol solvency.

Market Makers in DeFi

Market makers (MM) provide liquidity on decentralized exchanges (DEXs) and arbitrage price differences across venues. In RWA markets, their role extends to aligning on-chain prices with off-chain valuations.

• Market Makers must estimate fair value between NAV updates and manage deviations between DEX prices and primary markets.

• In addition, they often participate in liquidations (in Morpho vaults), contributing to vault (and underlying token and stablecoin) stability.

The Problem: NAV and RWA Pricing

RWA tokens are typically priced based on net asset value (NAV), which represents the per-token value of the underlying assets, calculated as the total value of the portfolio divided by the number of issued tokens. In practice, this value is updated periodically rather than continuously and is subject to constraints such as delayed redemptions and restricted access to primary markets.

This creates a situation in which on-chain prices must be formed without continuous reference points. Market participants estimate value between updates, while oracles select price sources that may diverge from DEX prices.

As a result, different parts of the system operate on different notions of value. When these diverge and cannot be arbitraged efficiently, instability emerges. Failures in such systems do not require exploits, but arise from the interaction of mechanisms that individually function as intended.

The Design Choice — and the Hidden Risk

While market makers aim to keep the price on DEXs aligned with the NAV, a fundamental question remains:

which price should lending protocols such as Morpho rely on when valuing tokenized RWAs used as collateral?

This is a core design choice (linked to the oracle) that directly determines how liquidation mechanisms of bad debt behave under stress.

1. DEX price

A first approach is to rely on the price observed on decentralized exchanges, potentially smoothed through time-averaging to reduce short-term manipulation.

Pros: The advantage of this approach is that it reflects the actual executable price at which tokens can be bought or sold. Liquidations based on this price are therefore directly actionable, as collateral can be sold immediately into the market.

Cons: This design assumes sufficient liquidity. In practice, RWA token markets on DEXs are often shallow. A large sale can move the price significantly, triggering further liquidations. This creates a feedback loop in which liquidations push the price down, which in turn triggers additional liquidations. As the DEX price diverges from the NAV, assets may be sold at a substantial discount, resulting in losses that are ultimately borne by liquidity providers in vaults.

2. NAV-based pricing

An alternative approach is to rely on NAV-based pricing.

Pros: This provides a stable reference point that reflects the underlying asset value and avoids liquidation cascades driven by temporary market dislocations. From the perspective of token issuers and long-term holders, this is an attractive property.

Cons: This approach shifts the burden to market makers and liquidators. If a position is liquidated based on NAV, the acquired tokens must be sold or redeemed through primary markets that are subject to frictions such as lock-ups, delayed redemptions, and minimum transaction sizes. Without sufficiently capitalized and specialized market makers willing to take on this risk, liquidations may not clear efficiently. In such cases, curators must explicitly account for this constraint when deciding whether and how to allocate capital to these markets.

3. Mix of data feeds

A third approach combines both sources, for example by blending NAV and DEX prices or introducing guardrails around deviations. While this can mitigate some extremes, it does not remove the underlying tension between continuous on-chain pricing and discrete off-chain valuation.

The Consequence for RWA Issuers

Once a persistent discount between NAV and DEX market price appears, its effects extend beyond trading inefficiencies and begin to impact the entire ecosystem around the token.

1. A discount directly affects confidence. Market participants interpret it as a signal that the token cannot be reliably redeemed or that liquidity conditions are insufficient. As a result, liquidity providers become more cautious and reduce their exposure, which further weakens market depth.

2. At the same time, trading activity deteriorates. Lower liquidity and wider spreads discourage participation, making it more difficult for market makers to maintain price alignment. The gap between NAV and market price can therefore persist or even widen over time.

3. In more extreme cases, these dynamics feed back into the lending layer. If the market price is used directly or indirectly in oracle construction, price dislocations can trigger liquidations. These liquidations introduce additional sell pressure on already thin markets, amplifying the deviation from NAV and reinforcing the downward cycle.

What begins as a pricing discrepancy can therefore evolve into a broader liquidity and solvency issue, affecting not only traders and liquidity providers, but also the credibility of the issuer and the viability of the token within DeFi markets.

Most tokenization efforts focus on issuance and primary market design, while the secondary market structure is treated as a secondary concern. The mismatch only becomes visible under stress, when pricing, liquidity, and liquidation mechanisms interact.

Closing Thought

For RWA tokens, scalability is not only a function of demand or yield. It depends on whether the system can maintain alignment between

• NAV,

• market price (DEX),

• and available liquidity.

If this alignment breaks, the tokenized RWA or yield bearing stabelcoin does not fail because of an exploit. It fails because its components, while individually correct, are not designed to operate together under realistic market conditions.

If you’re working on deploying yield-bearing or RWA tokens into DeFi, I’d be interested to compare notes.

More funds, crypto treasuries, and increasingly traditional financial players are either launching their own vault strategies, planning to do so, or allocating assets into curated lending products. For institutions, DeFi lending offers something traditional markets often struggle to provide simultaneously: transparency, programmability, and immediate liquidity.

It allows crypto-native users to increase exposure, rotate into stablecoins during volatility, or use leverage in a fully on-chain environment. For institutions, it offers programmable yield infrastructure that can be integrated into broader tokenized real-world asset (RWA) strategies.

Over-collateralized Lending without Lenders

DeFi lending is over-collateralized lending. There is no KYC on blockchain and no traditional lender assessing credit risk. In fact, there are no lenders in the classical sense. There are borrowers and there are smart contracts (DeFi protocols).

Liquidity providers (LPs) deposit capital into a liquidity pool. Borrowers take loans from that pool by posting more collateral than the value they borrow. The smart contract programmatically decides whether a loan is allowed, at what interest rate, and under which liquidation conditions.

DeFi lending is not peer-to-peer lending. It is peer-to-pool lending.

Liquidity providers are passive. They provide capital to a pool and earn the interest paid by borrowers. Interest rates are set by a utilization-based model (often referred to as a kink rate model). As utilization increases, rates increase. When supply overwhelms demand, yields fall. The mechanism is mechanical, transparent, and written in a smart contract.

With that foundation, let us turn to the two dominant DeFi lending protocols: Aave and Morpho.

Aave vs Morpho: Same Model, Different Design

Aave

Aave organizes liquidity per asset. Risk parameters are defined separately for each token, such as USDC, WETH, or WBTC. If you supply USDC, your capital joins a single USDC pool. Borrowers borrow from that same unified pool.

To list a new asset or change major parameters, a DAO vote is required. Liquidity is unified. Risk is standardized at the asset level.

If you want to supply USDC on Aave, it is simple. There is one USDC pool. You deposit to this pool and earn, while other borrow from it.

Morpho

Morpho takes a different path. Risk parameters are defined at the token pair level. WETH-USDC is a different market from WBTC-USDC. Each pair has its own loan-to-value ratios, liquidation thresholds, and configuration.

Curators.

Market creation is permissionless. Anyone can create a market with chosen parameters. Those who define and manage these markets are often referred to as curators.

This design increases flexibility and speeds up innovation. But it fragments liquidity across many markets.

Vaults.

To address this fragmentation, Morpho introduced vaults. Vaults aggregate liquidity and allocate it dynamically across multiple lending markets. Instead of supplying directly into a single pair, liquidity providers deposit into a vault that programmatically allocates capital across curated markets.

This explains why Aave does not need vaults. Because liquidity in Aave is unified per asset, there is no fragmentation to solve. In Morpho, fragmentation is a feature of flexibility. Vaults are the coordination layer that re-aggregate it.

Neither architecture is strictly superior. They reflect different trade-offs between standardization and granularity.

How to Evaluate a Morpho Vault

On Ethereum alone, there can be dozens of USDC-denominated vaults. Selecting one is not trivial. The first element most users look at is APY. This is often not enough.

1. APY - Beyond the Headline

A vault advertising a double-digit APY may look attractive, but the key question is how that yield is generated and how stable it is.

You should examine how volatile the yield has been historically. Determine how much of the yield comes from temporary incentive programs rather than organic borrowing demand. Check whether the vault charges management or performance fees, which can meaningfully reduce net returns. Also verify withdrawal conditions. Some vaults allow instant redemption, others impose delays of one to three days.

2. Total Value Locked and Yield Sensitivity

In lending protocols, yield is directly linked to utilization. When you supply more capital, utilization falls, and so does yield.

If your deposit represents a significant share of a vault’s total value locked, you may materially lower your own return. This is particularly relevant for institutional allocations.

One can estimate this sensitivity by analyzing the underlying interest rate model and simulating utilization changes. In my research (see the SoK DeFi https://arxiv.org/abs/2404.11281), we present how the kink model drives nonlinear yield responses. For large capital deployments, this type of analysis is essential.

A vault that looks attractive at current TVL may not look the same after your capital enters.

3. The Vault Token

Depending on the vault configuration, vaults accept different deposit tokens. These can range from various types of stablecoins to WETH and other assets. Before depositing into a vault that requires a deposit token other than mainstream assets like USDC or USDT, you should carefully evaluate the cost of acquiring and redeeming that token.

For institutions, this becomes especially important at scale. If you need to swap $1M+ into a less liquid deposit token, the slippage from the on-chain swap can be substantial. The same applies when exiting the position.

These transaction costs may significantly reduce the effective yield of the vault. In some cases, the APY advertised by the vault may not compensate for the entry and exit costs associated with the required deposit token.

4. Allocation and Diversification

Vaults allocate capital across multiple markets. If a vault allocates nearly all capital into a single market, that concentration should raise questions.

A well-structured vault should demonstrate diversification across collateral types and markets. It is also important to examine the nature of the underlying collateral. Exposure to major assets such as WETH or WBTC carries a different risk profile than exposure to more experimental yield-bearing stablecoins or niche RWAs.

Higher yield often correlates with higher smart contract, liquidity, or depeg risk. Properly calibrated risk parameters can mitigate some of these risks, but only if the curator has designed them carefully.

In Morpho, curator quality is central. The calibration of risk parameter directly affects LP safety.

5. Oracle Design

Oracle risk is frequently underestimated.

You should examine how prices are sourced. Is the vault relying on Chainlink feeds? On a time-weighted average price from a single DEX? On a multi-source aggregation?

Markets using thin liquidity pools as price references can be vulnerable to manipulation. For institutional allocators, oracle design is not a technical detail. It is core infrastructure.

Where Does the Yield Come From?

Ultimately, yield in lending vaults comes from borrowers.

Borrowers may be leveraging positions, engaging in basis trades, looping between lending pools and DEX liquidity, or funding structured strategies. In more advanced architectures, lending pools interact with DEX pools, and sometimes even with tokenized RWA structures.

For example, stablecoins can be deposited into a vault, allocated into lending markets, borrowed against tokenized money market assets, and looped through DEX liquidity. Off-chain distribution layers, including banks or fintech platforms, may connect retail capital into these on-chain strategies.

To understand better the yield origin, have a look at my previous blog post on this topic:

Conclusion

Morpho vaults are powerful tools for capital allocation. They enable granular risk management and dynamic market allocation. But they require deeper due diligence than unified lending pools.

Before allocating capital, understanding the difference between Aave and Morpho is a first step. It should be followed by the analysis of yield sustainability, TVL sensitivity, allocation concentration, risk parameter calibration, and oracle robustness.

DeFi lending is increasingly becoming institutional infrastructure. Infrastructure demands rigor, not headline chasing.

If you are building vault strategies, allocating institutional capital, or designing tokenized asset integrations into DeFi lending, thoughtful architecture and risk analysis matter more than temporary yield spikes.

Careful design always outperforms reactive allocation.
Serious capital deserves serious architecture.
