[RFC] Onboard Wintermute USDC Select Morpho V2 Vault to USDC Higher Risk Fleet

1. Summary

This proposal seeks to onboard a new yield strategy to the USDC Higher Risk Vault on Ethereum mainnet. This ARK allocates capital to the vault, built on the Morpho v2 infrastructure, allocating to bluechip collaterals alongside a selected set of higher-yield markets, and provides a competitive yield compared to other Morpho v2 vaults of the similar risk-levels.

If approved, the new ARK will expand the strategy set available to the USDC Higher Risk vault, allowing capital to be dynamically routed toward the Select yield opportunities, while maintaining diversification across strategies.

2. Motivation

By integrating the ARK, the USDC Higher Risk Vault can capture elevated yield while maintaining a core of bluechip exposure across Morpho infrastructure. The strategy interacts with markets using cbBTC, WBTC and wstETH as collateral, amplified by select higher-yield markets including v-wmtUSDC, reUSD and PT-USDat.

Armitage is a dedicated curation arm of Wintermute, a global leading algorithmic trading firm in digital assets, founded in 2017 and today trading over $10B in daily volume across 70+ venues. Armitage brings together strong DeFi expertise, end-to-end risk execution and trading informed risk management.

Average APY for the Armitage Select Morpho vault over the last 30 days is 4.48%.

4. Risk Assessment

Lazy Summer Protocol currently has significant exposure to Morpho, and a number of V2 vaults have already been onboarded as ARKs; therefore, it is not expected to create any new risks to the protocol, both from a technical and economic viewpoint.

While this strategy introduces indirect exposure to the higher-yield collateral assets listed above, that risk is contained by the curator’s risk management practices: Wintermute can execute liquidations directly for every market the vault supports rather than relying on third-party liquidators, and positions are monitored in real time with automated deallocation from any market showing signs of an exploit or economic stress.

The Wintermute USDC Select vault currently has collateral exposure to the following assets:

5. Next Steps

  1. Risk Review: Tagging @BlockAnalitica to provide a risk classification and suggest initial deposit caps for this ARK.

  2. DAO Signal: Gather feedback from @Recognized_Delegates

  3. SIP Promotion: Once risk parameters are defined, promote this to a formal SIP for on-chain execution.

IMO the Higher Risk Fleet is here to accommodate strategies with a higher yield profile while maintaining disciplined risk management, so this appears well aligned with the fleet’s objectives. The additional context around the underlying markets and active risk management is appreciated.

I am curious about opinions of other @Recognized_Delegates, and possibly adding this strategy to the DAO-Risk-Managed USDC Fleet too?

Similarly to [RFC] Onboard Wintermute USDC Prime Morpho V2 Vault to USDC Lower Risk Fleet I am looking forward to see @BlockAnalitica review of the collateral mix and recommended exposure limits before moving toward a SIP.

This vault seems like a good addition to the DAO Risk Managed Vault, but I’m curious to see @BlockAnalitica due diligence on some of the collateral assets included in the vault.

Wintermute USDC Select Morpho V2 Risk Assessment for Mainnet USDC Higher Risk Fleet

Block Analitica reviewed the Wintermute USDC Select vault, curated by Armitage, the single vault covered by this RFC for the USDC Higher Risk fleet.

Select shares the same Morpho Vault V2 infrastructure and Owner/Curator Safes as the Wintermute USDC Prime vault, extended with three additional markets: v-wmtUSDC, PT-USDat (redeeming to USDat), and PT-reUSD (redeeming to reUSD). reUSD is already onboarded elsewhere in Lazy Summer and does not add new risk exposure. v-wmtUSDC and USDat are new and require assessment.

Collateral Exposure

Underlying Market Collateral LLTV
cbBTC/USDC cbBTC 86%
wstETH/USDC wstETH 86%
WBTC/USDC WBTC 86%
v-wmtUSDC/USDC v-wmtUSDC 86%
PT-USDat-27AUG2026/USDC PT-USDat 91.5%
reUSD/USDC reUSD 91.5%
PT-reUSD-25JUN2026/USDC PT-reUSD 91.5%

v-wmtUSDC. Wintermute borrows USDC uncollateralized on Wildcat (9.25% fixed at Armitage’s launch, per Cryptobriefing), wraps the resulting lender claim into v-wmtUSDC, and adds it as Select collateral. Wildcat market tokens rebase upward at the borrow rate, so v-wmtUSDC’s nominal balance climbs over time as long as Wintermute keeps servicing the loan, independent of whether its underlying credit is deteriorating. Block Analitica could not identify a DEX pool or other trading venue for v-wmtUSDC, so without an independent market, there is nothing forcing an earlier markdown if Wintermute’s credit weakens; the balance can keep rising right up to a default, then reprice sharply. It is also the same credit risk counted twice: v-wmtUSDC is a claim on Wintermute’s own solvency, so using it as collateral to borrow more USDC means both positions fail together if Wintermute’s credit weakens, with no separate asset standing between them.

On-chain data as of June 30, 2026: the v-wmtUSDC/USDC market is 99.99% funded by the Select vault itself ($5.24M of $5.24M supply), at 90.30% utilization with only ~$508k liquid. At the vault level, this market is 16.03% of TVL ($5.24M of $32.71M), capped at $25M absolute (76% of current TVL) with a 100% relative cap. Separately, one address holds 92.13% of vault deposits ($30.15M of $32.71M).

Transaction history for the two largest borrowers confirms active leverage looping rather than one-off collateral posting. The largest borrower (26.99% of borrow share) shows a repeating cycle of depositing into Wildcat’s wmtUSDC market, wrapping the claim into v-wmtUSDC, and supplying/borrowing on Morpho via a single Bundler3 multicall, executed roughly a dozen times in succession. The second-largest borrower (19.60% of borrow share) shows the identical pattern, but from a wallet with under $1 in token holdings, first active only 30 days ago, topped up with small ETH amounts by a single funding address before each step, consistent with an automated execution wallet rather than an independent lender. Together these two addresses represent 46.6% of the market’s borrow share.

Put together, the Select vault introduces a market where Armitage/Wintermute-controlled curation policy sets exposure limits, the collateral is linked to Wintermute-related credit, and Wintermute presents liquidation execution as part of the Armitage risk-control stack. The vault’s own deposits fund most of the market, and a large share of borrow demand appears to come from repeated leverage-loop activity rather than broad third-party usage. That combination, rather than the collateral label alone, is why Block Analitica does not consider this exposure suitable for curator-delegated onboarding at this stage.

The RFC claims Wintermute “can execute liquidations directly for every market the vault supports rather than relying on third-party liquidators,” with automated deallocation on signs of stress. For v-wmtUSDC, the liquidator and the insolvency event are the same entity, so this does not hold as a backstop for that market.

USDat (via PT-USDat). New exposure. USDat is Saturn Credit’s stablecoin: it is minted and redeemed 1:1 with USDC through Saturn’s interface, but its reserves target 100% $M, M0’s tokenized US Treasury-bill product, rather than holding USDC, per Saturn’s own documentation. Block Analitica confirmed this directly on-chain: the USDat contract holds 111.33M $M against a USDat total supply of 111.30M, a matching 1:1 balance. Saturn Credit launched on mainnet on April 8, 2026, per Stacy Muur’s coverage; it has not operated through a full market cycle or stress event.

Governance is identical to Prime. Per safe.yaudit.dev, the Curator Safe (0x4687e45bb5518a995913a24bb2816fe2031d74d8, 3-of-5) scores 92/100 Low Risk, deployed April 23, 2026. The Owner Safe (0xb83a77677c51aaf6c45b0b64199eae6938559e5e, 4-of-6) scores 87/100 Low Risk, deployed April 27, 2026. Both are EOA-only signers, with critical curator actions timelocked 3-7 days.

Fleet Classification

  • Wintermute USDC Select (0xA2EAaD0D586cF9FD73bb2c09cF6A7E3e187D68cd): cbBTC, wstETH, and WBTC are blue-chip. reUSD sits within the fleet’s risk appetite as an already-onboarded asset. USDat is new, but its Treasury-bill backing was confirmed directly on-chain; the residual risk is Saturn Credit’s youth as an issuer. v-wmtUSDC is the issue, for the reasons above.

Conclusion

Block Analitica does not recommend onboarding Wintermute USDC Select to the curated USDC HR fleet at this stage, given the v-wmtUSDC findings above; the risk profile is not justified by the vault’s current ~4.1% yield. This structure may be more appropriate for DAO-managed fleets, where governance can accept the risk directly rather than through curator delegation.

This assessment reflects publicly available and on-chain data as of June 30-July 1, 2026, and should be reverified before any governance action.

First things first, we appreciate the time and effort spent on assessments for both Prime and Select. At the same time, we want to clarify points regarding the v-wmtUSDC market and seek to continue the discussion (for example, in the context of DAO-managed fleets), even where it may not change the conclusion.

Liquidity

Providing liquidity through AMM pools for private credit products is not very sustainable as it incurs a high cost of capital. Hence, the liquidity is provided through RFQ/solvers, like UniswapX. Currently, the capacity is at ~500k wmtUSDC under minimal (sub 5 bps) slippage. In case of potential insolvency one could expect secondary creditor claims markets to emerge.

Saying all this, we want to note that Wintermute doesn’t have any admin functionality for the instant burning of debt tokens in its possession; hence, providing a sizeable instant exit opportunity at any time will lead to unnecessary capital inefficiency. Armitage is also in consideration of alternative designs for this specific asset, by tranching or looping through protocols like 3F.

Earlier markdown

While the general logic could apply to certain onchain private credit products, the devil is in the details. Wildcat, as a protocol, pushes borrowers to honour redemptions by imposing a delinquency penalty. For wmtUSDC, the grace period before delinquency is 48 hours, so holding redemptions open for 2 days straight increases the APR by 5%. That’s enough to make the loan expensive for the borrower quickly, though not by itself sufficient to derisk the Morpho market.

Market derisking is handled by another safeguard implemented at the vault level: the bespoke market oracle for Wildcat markets. The oracle operates on the delinquency time accumulator from the wmtUSDC market and applies a price discount proportional to the duration of the delinquent state. So, aggressive loopers could be derisked pretty quickly given oracle parameters.

We’d note this addresses the “no markdown before default” concern directly for the delinquent case, but we recognize it doesn’t cover credit deterioration. That gap is inherent to any point-in-time credit product without continuous external pricing, not specific to this market.

Same risk counted twice

On the concern that v-wmtUSDC collateral used to borrow more USDC double-counts the same credit exposure: this is accurate in the sense that both legs share the same ultimate counterparty risk. We don’t think this is unique to this market structure, given it’s true of any leverage looping involving correlated risk.

Supply and borrowing demand

We work on reducing the supply concentration risk caused by seed capital that does not leave the vault at the bootstrap stage. Regarding being the only lender for this market, it was deployed by Armitage, incl. the mentioned oracle. We have mid-term plans to increase liquidity by onboarding additional curators. The main roadblock is determining the form that private credit should prevail (e.g., tranching or 3F) or if it worth for them to coexist, rather than growing this market first and pushing for the migration later.

In regards to caps:

  • $25M as an absolute cap is more than necessary, and that’s the one we set in expectation of growth and the fact that we’ll be the only curator for some time. The idea here is that raising the cap is more expensive in terms of time (because of the timelock) than decreasing it. We’d be glad to consider decreasing it by a factor of 3 to make the exposure risk more controllable.
  • 100% relative cap follows similar logic, and relative caps are implemented internally within our allocation engine. The relative cap we use internally is 17.5%, with a bit of extra space if needed, given being the only lender for v-wmtUSDC market.

Looping strategy is an expected use case for this market, which makes economic sense given the positive carry spread, similar to the AA_FalconXUSDC/USDC market, or existing Pendle markets. We would like to see more third-party usage in the form of repo deals, but the market is still nascent in this regard, and the spread makes looping lucrative, similar to the 3rd-party examples mentioned.

On the topic of borrower concentration, we want to note that two of the mentioned loopers are known to us (experienced DeFi farmers without any ties to Armitage/Wintermute) and performed looping in a way that was convenient for them, given the lack of current support for this market on platforms like DeFi Saver. There is additional demand for looping in this market; we don’t plan to serve it at the moment to support a more responsible rollout.

Liquidations

Concerning a potential insolvency event (the same logic applies to depeg events, which we witness quite often nowadays), liquidator identity is of no importance as nobody would take the underlying asset on the balance sheet at the value assumed by the market oracle. We acknowledge that the liquidator may not appear to be a strong backstop compared to other markets in the event of insolvency for v-wmtUSDC. However, the oracle was designed to decrease the price each day until it reached $0.01, while anyone could buy claims on this collateral at any discount and repay the debt at least partially.

Outside the insolvency case, at 100% utilization and/or an extended delinquency state flagged by the oracle, speculatively liquidating to buy debt at a discount and redeem it is also economically viable for third parties. This incentive creates the backstop rather than any specific liquidator identity on this market.
