What is Aave: Ethereum's Popular DeFi Lending Protocol
Aave is a decentralized cryptocurrency lending platform that allows users to deposit or borrow crypto assets without intermediaries. Similar to traditional banks but fully automated, Aave enables:
- Depositors to earn passive income by providing liquidity.
- Borrowers to take out loans by collateralizing their crypto holdings.
Initially built on Ethereum, Aave V3 now supports 6 additional blockchains including Avalanche, Polygon, and Arbitrum, offering 30+ crypto assets like BTC, ETH, and USDC.
Key Features of Aave's Lending Protocol
Liquidity Pools System
Aave uses liquidity pools where:
- Deposits generate interest-bearing aTokens (e.g., aETH for ETH)
- Borrowing requires overcollateralization with dynamic interest rates based on pool utilization.
