Advanced Aave Strategies

Loop strategy: supply ETH, borrow USDC, buy more ETH, supply again — creates 3–5x leveraged ETH exposure with liquidation risk. Stablecoin carry: supply USDC, borrow at lower rate on another stablecoin, supply to higher-yield protocol — 1–3% risk-free spread when rates align. Always model liquidation scenarios before using leverage.
