what's summer.fi?
Summer.fi is a DeFi protocol that provides automated yield optimization for users' crypto assets, focusing on stablecoins and other tokens through AI-powered vaults. It operates across multiple blockchains like Ethereum Mainnet, Base, Arbitrum, and Sonic Labs, allowing depositors to earn yields via lending, borrowing, and rebalancing strategies without manual intervention. The protocol's Lazy Summer feature automates capital allocation to high-performing markets, using keepers to monitor and adjust positions in real-time for efficiency and risk management. Key components include lower-risk and higher-risk vaults tailored to different user preferences. Lower-risk vaults emphasize capital preservation through diversified lending across established protocols like Aave, Morpho, and Compound. Higher-risk vaults, such as the USDC Higher-Risk Vault, pursue aggressive yields by exposing capital to more dynamic opportunities in markets like Euler and Avantgarde, with AI rebalancing to capture returns while mitigating downside through on-chain automation. Governance is handled by SUMR token holders, who vote on strategy proposals, while risk assessment is supported by partners like BlockAnalitica. The protocol emphasizes transparency, with all positions fully on-chain and verifiable, making it suitable for both retail and institutional users seeking passive income in DeFi.
summer.fi generates 0.66% revenue per dollar from day one of operations.
