Zama Launches Confidential USDC Yield Vault on Morpho
Confidential tokens can now earn yield on Ethereum. Zama protocol’s Fully Homomorphic Encryption (FHE) stack is powering confidential USDC, cUSDC, which until now was mainly used for private transfers and custody. Starting June 23, institutional and retail users can deposit cUSDC into a yield product for the first time which includes Steakhouse Confidential USDC Prime, a vault curated by Steakhouse Financial and deployed on Morpho.
What Changes and Why it Matters
Public blockchains expose deposit sizes, timing, and wallet addresses. For large institutional traders, that visibility creates two problems: first, it reveals strategy to competitors and invites front running. Morpho’s lending markets already deliver competitive yields and deep liquidity, but institutions have usually stayed on the sidelines because every allocation signals intent onchain.
Zama’s cUSDC keeps balances and transaction amounts encrypted onchain using FHE. This means deposits into the Steakhouse Confidential USDC Prime vault will not broadcast position sizes or exact timing, while the vault itself still uses Morpho’s live market infrastructure. In short, the same underlying strategy and risk profile are preserved, but the depositor’s operational details remain private.
How it Works in Three Steps
Shield USDC into cUSDC. Users convert regular USDC into confidential USDC with one transaction within the Zama app. There is no need for bridges, new chains, or extra wallets.
Deposit cUSDC into the vault. The Zama app routes confidential deposits into the Steakhouse Confidential USDC Prime vault, which plugs into Steakhouse’s existing USDC Prime Vault on Morpho.
The user can earn yield. The vault accrues yield through Morpho’s lending markets by supplying USDC collateralized against blue-chip crypto assets such as cbBTC, WBTC, wsETH. The yield is identical to Steakhouse’s flagship strategy, with amounts encrypted onchain.
Same Vault, Same Strategy, More Privacy
Steakhouse Confidential USDC Prime is not a new investment structure. It has been mirroring Steakhouse Prime v2, the firm’s flagship USDC vault on Morpho, with unchanged vault parameters, collateral basket, and credit curation. The only difference is the deposit surface: cUSDC replaces visible USDC. Security, capital efficiency, and performance characteristics remain those of Morpho and Steakhouse’s existing products.
This design choice is intentional. Instead of forcing DeFi protocols to be rebuilt around privacy. Zama’s approach layers confidentially onto established systems. Existing smart contracts and risk models remain intact while deposit-level information gets encrypted.
What Institutional Users Gain
For trading desks and institutional allocators, confidentiality is the key selling point. Morpho already hosts more than $11 billion in deposits across its markets. Steakhouse Financial manages over $4.5 billion in total value locked across vaults, powering products at major custodians and wallets. Those numbers show the yield exists; the friction has been public signalling.
Merlin Egalite, Morpho co-founder, raised a concern that institutions want the onchain efficiencies of DeFi without revealing sensitive operational details. By combining Zama’s FHE layer with Morpho’s vaults, institutions can allocate capital custodians use, without exposing position sizes or timing.
Regulation and Auditability
Zama and Steakhouse emphasize that confidentiality does not mean opacity for auditors or compliance teams. The confidential deposit model is built in a way that the underlying capital and vault activity remain auditable whenever required, while deposit sizes stay encrypted. This balance aims to meet institutional needs for both privacy and regulatory oversight.
Launch Campaign and Incentives
For adoption to grow, Zama is carrying out a shielding campaign from June 17 to June 22. Users who shield at least 10 USDC into cUSDC during the window receive entries into an onchain draw on June 23. Every 10 USDC shielded equals one entry, capped at $500 per wallet. Twenty-five winners will receive $1,000 in cUSDC each, for a total $25,000 prize pool. The draw itself uses Zama’s FHE-powered randomness.
What Comes Next
This vault is the first concrete product in a broader plan to marry Zama’s confidentiality stack with Morpho’s vault architecture. The integration establishes a template: pick a high quality existing vault, add a confidential deposit asset, and enable institutions to enter without broadcasting their playbook.
Bringing FHE into core DeFi primitives marks a new phase for privacy on public blockchains. If adoption grows, confidential deposit surfaces could become a standard on institutional rails into DeFi, letting capital flow more freely without losing the transparency and security that protocols like Morpho already offer.
