Zama, Morpho, and Steakhouse Financial are rolling out what they call the first DeFi yield product built for Confidential USDC on Ethereum. The vault, set to accept deposits starting June 23, uses fully homomorphic encryption to let users earn yield without exposing their balances or transaction history.
What Confidential USDC actually does
Confidential USDC is a privacy-focused token that encrypts every transfer's amount and sender-receiver details while still allowing on-chain verification. Until now, that encryption stopped at simple transfers. This vault extends FHE into the lending layer — meaning users can supply the token to a Morpho lending pool and earn interest, all while keeping their position under wraps.
How the vault works
Steakhouse Financial curated the vault on top of Morpho's lending protocol. That means the vault selects a specific set of lending markets and rebalances automatically. Zama provides the FHE infrastructure that keeps the USDC amounts encrypted even as they're being lent out. The result: a borrower's collateral and a lender's supply both stay confidential, which is new for Ethereum DeFi.
FHE has been talked about for years, but most applications stuck to simple payments or data sharing. This product pushes it into yield generation — a core DeFi activity. For the roughly $1.5 billion TVL sitting in Confidential USDC, this is the first real way to put it to work without breaking privacy. The timing comes as regulators in Europe and the U.S. push for more compliant privacy solutions, though no single rule forced this launch.
When and how to get in
Deposits open June 23. There's no whitelist or minimum lockup listed yet. The vault will be accessible through Morpho's interface and Steakhouse Financial's dashboard. Anyone holding Confidential USDC on Ethereum can participate. Whether other tokens follow depends on how this first batch of depositors — and the yields — perform.
