Aave

Aave is a decentralized lending protocol operating on Ethereum and multiple Layer 2 chains, where users deposit cryptocurrency to earn yield and borrow against collateral. The protocol uses algorithmic interest rates determined by supply and demand, with AAVE serving as the governance token that controls parameter adjustments, risk management, and treasury allocation. Smart contracts enforce collateralization requirements and liquidation mechanics—the core mechanics that have scaled the protocol to consistently rank among the largest DeFi platforms by total value locked.

Traders monitor Aave as a structural indicator of leverage appetite and collateral demand across DeFi. Its borrow-to-supply ratio, liquidation events, and governance activity signal risk sentiment in the broader ecosystem. AAVE token liquidity is substantial across major venues, and the protocol's deployment across chains creates arbitrage opportunities in borrowing costs. As a liquid large-cap DeFi asset with direct exposure to on-chain credit conditions, Aave often correlates tightly with broader Ethereum volatility while serving as a barometer for institutional DeFi participation.
