Zama is set to launch a DeFi vault for encrypted stablecoin deposits on June 23. The product will introduce Confidential USDC yield through Morpho and SteakhouseFi. It will let users earn returns while keeping positions encrypted on Ethereum.
The vault is called Steakhouse Confidential USDC Prime. It will facilitate Confidential USDC (cUSDC). Zama announced the plan through a detailed post on X.

Confidential USDC Yield Adds Privacy to DeFi Lending
The product extends Zama’s confidential token to lending. That system relies on Fully Homomorphic Encryption (FHE). The technology enables processing of encrypted data without exposing the original values.
In the Confidential USDC yield product, deposits will be directed to the Morpho lending markets. During the process, user balances and positions will remain encrypted. Zama said that the design brings privacy to the current Ethereum DeFi infrastructure.
Most wallet activity is exposed with standard DeFi lending. On-chain transaction timing, amounts, and balance can be checked. This creates concerns for users who do not want public treasury movements.
The new vault will work to minimize that visibility. cUSDC is the first step in which users convert regular USDC to cUSDC via the Zama application. They can then deposit the encrypted token into the Steakhouse Confidential USDC Prime vault.
The funds deposited will be transferred to the already existing Steakhouse Prime v2 Morpho strategy. The lending strategy for the vault will be the same as the lending strategy of Steakhouse’s regular USDC Prime vault, Zama said. It will also employ the same collateral selection and risk parameters as well.

Morpho Markets Support Zama’s Confidential Yield Strategy
The primary modification is encryption. All of the assets placed in the confidential vault are kept private during the strategy’s operation. This allows users to use Confidential USDC yield without being exposed.
The vault will be based on markets provided by Morpho, with large collateral assets. These are cbBTC, WBTC, and wstETH. SteakhouseFi will still be responsible for credit allocation in the lending strategy.
Zama has no plans for creating a new lending protocol for the product. Rather, it’s introducing confidentiality to pre-existing DeFi tools built on Ethereum. That approach ensures that the yield model remains anchored to the existing infrastructure.
The launch could be of interest to institutional users. A large on-chain deposit can indicate the treasury activity and strategy timing. Firms managing sizeable capital may also face competitive risks due to public visibility.
Sébastien Derivaux, co-founder of SteakhouseFi, noted that confidential deposits can be a way for institutions to apply existing USDC yield strategies. He said they can do this without publicly disclosing position sizes. He also cited ‘compliance and auditability’ as key issues.
Morpho Demand Rises as Zama Continues cUSDC Yield Rollout
The Confidential USDC yield launch comes as Morpho attracts more stablecoin treasury products. Yield products for treasury and institutional users have been developed using Morpho’s framework. These products are based on lending markets rather than on different systems.
The rollout also comes in the wake of a legal problem with Zama. A U.S. federal court lifted the temporary restraining order on June 1, according to founder Rand Hindi. The order had restricted access to approximately $12.5 million worth of USDC.
The Confidential USDC contract has been temporarily impacted by that dispute. The resolution cleared the way to access the locked funds, according to Hindi. Zama is now moving ahead with its Confidential USDC yield plan.
The launch will be a test of the demand for lending in encrypted stablecoins. It also introduces privacy capabilities in a live DeFi yield strategy. The Confidential USDC yield vault is a prime example of the potential applications of encrypted tokens beyond transfers and storage.
