Summer.fi offers two tiers of risk-managed vaults to serve different investor profiles:
🟢 Lower Risk Vaults
Stick to single-chain, non-leveraged strategies with near-instant withdrawals and transparent, high-quality collateral. No exposure to peg or swap risk.
🟠 Higher Risk Vaults
May include leverage, cross-chain bridges, or dynamic strategy rotation for higher potential returns. Suitable for experienced DeFi participants seeking higher yield.
