YO Protocol

Non-custodial ERC-4626 yield optimizer on Base and Ethereum; agents deposit stablecoins into yoUSD to earn aggregated DeFi yield.

Overview

YO Protocol is a multi-chain yield optimizer built on ERC-4626 vaults, currently reporting roughly $12.9M TVL and an 8% yield on its yoUSD product. An agent builder uses it as a deposit target for idle stablecoin balances, routing funds into the vault via standard ERC-4626 deposit/withdraw calls rather than managing individual yield strategies directly.
