Overview

Hold a position in a public ERC-4626 vault while the amount stays encrypted, powered by Zama FHEVM.

Confidential Vaults connect confidential tokens to public ERC-4626 yield vaults. Users deposit encrypted amounts, the protocol pools them into a batch, and only the batch total is decrypted and settled against the vault. Observers see who participated and the batch total — never an individual amount.

The encrypted arithmetic runs on Zama FHEVM, which computes directly on ciphertexts on Ethereum. Balances and per-user amounts exist on-chain only as ciphertext handles, and each user can decrypt their own position.

Every step of a batch's lifecycle — dispatch, settlement, claim — is a permissionless contract call, and a user can always recover their funds with their own transactions.

Batch Lifecycle

How a batch moves from encrypted joins to settled claims.

Confidentiality

What stays encrypted, what is public, and the known limits.

Trust Model

Who can do what, and how users recover funds on their own.
