YO is a DeFi protocol developed by Exponential.fi that automatically optimizes the yield of crypto assets. It distributes users' funds across the highest-yielding pools on various blockchains (e.g., Ethereum, Base, Solana), using risk ratings from Exponential.fi to balance yield and security.Users connect their wallet, deposit assets (e.g., yoUSD, yoETH) into yoVaults (based on the ERC-4626 standard), and YO continuously rebalances them between pools to maximize returns. The protocol is fully decentralized, non-custodial (users retain control over their assets), and the selection of pools is partially determined by the community.
