Description
Autonomous cross-chain yield optimization agent using MetaMask Smart Accounts Kit + ERC-7715 Advanced Permissions. Deployed custom YieldCaveatEnforcer on Base mainnet (0xf0423bf51f494ccaf75b122b79388bfe3028ac03) - on-chain guard restricts agent to only call Aave V3 and LI.FI contracts. User grants one ERC-7715 permission via MetaMask UI, agent autonomously redeems delegation every 60s to deposit USDC into highest-yield Aave V3 pool. No fund movement, no vault - funds stay self-custodial in user MetaMask wallet throughout.
