Encrypted USDC vault debuts on Ethereum
Zama, Morpho, and Steakhouse Financial are set to launch the Steakhouse Confidential USDC Prime vault on June 23, introducing what they describe as the first decentralized finance yield product enabling encrypted USDC holdings on Ethereum. The offering allows institutional participants to generate yield without exposing balances, portfolio composition, or transaction activity on public ledgers.
The vault integrates Zama’s fully homomorphic encryption with Morpho’s lending infrastructure. This setup enables deposits of encrypted USDC, or cUSDC, while preserving auditability and compliance requirements alongside transaction privacy.
How the technology works
Fully homomorphic encryption allows smart contracts to process encrypted data without decrypting it. In practice, this means financial operations can be executed while sensitive inputs remain hidden. Unlike earlier privacy solutions that emphasized anonymity, this model focuses on selective transparency, allowing verification without full disclosure.
Users convert standard USDC into cUSDC directly on Ethereum, avoiding the need for cross-chain bridges. These encrypted tokens are then stored in Morpho vaults, benefiting from the platform’s capital efficiency and security framework.
Institutional infrastructure behind the vault
The vault is built on established components in the digital asset lending space. Morpho recently raised $175 million from firms including Paradigm, a16z crypto, Ribbit Capital, Apollo Funds, Circle Ventures, and VanEck, bringing its valuation close to $2 billion.
Steakhouse Financial, which manages risk for the vault, has developed a reputation for institutional-grade strategies and already oversees billions in assets on Morpho. The firm previously launched a separate vault focused on Société Générale’s MiCA-compliant EURCV stablecoin.
Zama has also expanded its institutional footprint following earlier challenges. A court-ordered blacklist earlier this year temporarily affected its smart contract after $12.6 million tied to an Overnight Finance dispute entered the system. The company stated the issue was unrelated to its protocol design. Since then, Zama has acquired TokenOps and partnered with Apex Group-backed T-REX Network to support encrypted tokenized assets under the ERC-3643 standard.
Market context and adoption signals
The launch comes as market sentiment shows divergence. Broad flows have weakened, with US spot bitcoin ETFs seeing roughly $2.43 billion in net outflows in May 2026, marking the weakest monthly performance of the year. At the same time, capital continues to move into infrastructure focused on onchain credit and privacy.
Analysts are watching early adoption of the confidential vault as a signal of demand for privacy-preserving yield strategies. Asset inflows and usage patterns could indicate whether large-scale traders are ready to shift capital toward encrypted onchain finance.
Integration and distribution potential
Similar lending structures are already being integrated into mainstream platforms. Coinbase has rolled out non-encrypted yield vaults using the same lending protocol and risk curator, offering prime and high-yield options based on collateral quality. These products demonstrate how complex decentralized finance strategies are being packaged for broader access.
The confidential vault builds on this trend, adding a privacy layer that could address long-standing concerns among institutional participants about transparency on public blockchains.
Token price snapshot
As of Wednesday, ZAMA traded at around $0.035, while MORPHO was priced near $1.92, according to available market data.
