Zyfai — Yield for Any Wallet

Turn any Ethereum wallet into a yield-generating account.

What This Does

When a user wants to earn yield on their crypto, Zyfai creates a deterministic subaccount (Safe smart wallet) linked to their existing wallet (EOA). Funds deposited into this subaccount are automatically optimized across DeFi protocols. The user stays in full control and can withdraw anytime.
