A groundbreaking collaboration between Zama, Morpho, and Steakhouse Financial is set to introduce the first decentralized finance (DeFi) yield product for Confidential USDC (cUSDC) on the Ethereum blockchain. The new Steakhouse Confidential USDC Prime vault, opening for deposits on June 23, 2026, aims to unlock yield opportunities for institutional investors by enabling private stablecoin transactions. This initiative addresses the long-standing challenge of confidentiality in public blockchain environments, a significant barrier to institutional DeFi adoption.
The partnership leverages Zama's Fully Homomorphic Encryption (FHE) technology to allow users to convert standard USDC into a shielded cUSDC version, where balances and transaction amounts remain encrypted. This cUSDC can then be deposited into Steakhouse Financial's existing Prime USDC vault, which operates on Morpho's decentralized lending protocol. Merlin Egalite, co-founder of Morpho, noted that institutional demand for on-chain confidentiality has been a consistent signal from prospective users, and Zama's stack allows institutions to allocate into Morpho vaults without compromising operational privacy.
Dr. Rand Hindi, Co-founder and CEO of Zama, emphasized the significance of this development, stating, "Until now, operating on a public blockchain meant exposing your entire financial playbook to your competitors." He added that by integrating FHE into core financial primitives like lending vaults, they are proving that privacy and decentralization are no longer mutually exclusive, marking the official launch of the Confidential DeFi category on Ethereum. This integration simplifies a complex cryptographic process into a seamless user journey, enabling institutions to earn yield without broadcasting their positions.
Sébastien Derivaux, Co-founder of Steakhouse, highlighted that their USDC Prime vault is designed to be highly liquid and risk-conscious. He explained that Zama's confidentiality layer integrates directly into this framework, allowing institutions to access the same strategy without broadcasting their positions, ensuring privacy where needed, with compliance and auditability intact. The vault utilizes the same lending strategy, collateral selection, and risk parameters as Steakhouse’s flagship USDC Prime vault, with the primary difference being the encryption of deposited assets.
The launch is poised to be a pivotal moment for institutional engagement in DeFi, offering a solution that combines the transparency and efficiency of public blockchains with the operational privacy required by corporate treasuries and asset managers. The confidential version of the Steakhouse USDC Prime vault on Morpho will officially open for deposits on June 23, 2026, via the Zama app.
