Wintermute launches Armitage on Morpho, wraps uncollateralized debt with $53M TVL

Wintermute, one of crypto’s largest market makers, just became its own bank, borrower, and collateral issuer all at once. The firm launched Armitage, a vault curation business on Morpho, pulling in roughly $53 million in total value locked across two USDC vaults within days of going live on May 19.

The setup works like this: Wintermute borrows USDC on the Wildcat protocol at a fixed 9.25% APR, with no collateral backing that loan. It then wraps that borrowed position into a token called v-wmtUSDC, deposits it into one of the Armitage vaults, and uses it as collateral to borrow even more USDC. In English: the firm turned its own unsecured IOU into an asset that lets it borrow again.

Two vaults, two risk profiles

Armitage launched with a pair of USDC-denominated vaults, each targeting different appetites for risk. The USDC Prime vault is the conservative option, holding $20.61M in TVL and generating a net APY of 3.65%. It focuses on blue-chip collateral.

The USDC Select vault attracted $32.4M in TVL, offering a 4.2% net APY at launch with a stated target range of 5-8% net APY over time. The higher yield comes from its willingness to accept a more diverse collateral mix that includes v-wmtUSDC, the wrapped version of Wintermute’s unsecured borrowing activity.

The math on the yield spread matters here. Wintermute pays 9.25% to borrow unsecured on Wildcat, then re-deploys that capital through a vault structure designed to generate returns north of that cost. If the Select vault hits its 5-8% APY target for depositors, Wintermute needs the underlying lending activity to produce enough margin to cover the 9.25% borrowing cost, pay depositors, and still turn a profit.

The role concentration problem

Wintermute isn’t just curating these vaults. It’s simultaneously the entity that borrows unsecured on Wildcat, the issuer of the wrapped token used as collateral, the curator deciding which collateral gets accepted, and one of crypto’s most active market makers who would presumably handle liquidations.

If Wintermute’s unsecured borrowing position on Wildcat ever came under stress, the v-wmtUSDC token sitting as collateral in the Select vault could lose value. The entity responsible for managing that risk in the vault is also the entity whose financial health determines whether the collateral is worth anything.

What Morpho gains from the arrangement

Morpho’s CEO Paul Frambot praised the launch, framing it as a boost to the protocol’s curator ecosystem. The plan, according to the firm, is to leverage its existing risk management and liquidation capabilities to accept a wider variety of collateral on Morpho, including tokenized debt instruments and other assets that sit outside the typical DeFi comfort zone of ETH, stETH, and major stablecoins.

What this means for investors

The $53M TVL figure signals real demand for yield products that go beyond vanilla stablecoin lending. The USDC Prime vault at 3.65% APY offers a more conventional risk profile, while Select’s 4.2% current APY, with aspirations toward 5-8%, prices in the additional collateral risk.

Watch the Select vault’s collateral composition closely. If v-wmtUSDC grows as a share of total collateral, the vault’s risk profile becomes increasingly tied to Wintermute’s own creditworthiness. At that point, what looks like a diversified lending vault starts to resemble a corporate bond with extra steps.
