Introduction
Aave is a leading decentralized finance (DeFi) protocol specializing in peer-to-peer lending, borrowing, and earning interest on cryptocurrencies—all without intermediaries. Built initially on Ethereum, it now supports multiple blockchains, including Avalanche, Fantom, and Polygon, offering users flexibility and scalability.
Key Features
- Decentralized Lending/Borrowing: Users can lend or borrow crypto assets directly via smart contracts.
- Liquidity Pools: Depositors earn interest by contributing to pooled funds.
- aTokens: Interest-bearing tokens representing deposits (e.g., aETH for Ethereum).
- Flash Loans: Uncollateralized loans repaid within one transaction block.
- Governance: AAVE token holders vote on protocol upgrades.
A Brief History
- 2017: Launched as ETHLend by Stani Kulechov, raising $16.2M in its ICO.
- 2018: Rebranded to Aave (Finnish for "ghost") and shifted to a liquidity-pool model.
- 2020: Officially licensed by the UK Financial Conduct Authority.
- 2022–23: Expanded with Lens Protocol (decentralized social media) and GHO stablecoin.
How Aave Works
1. Lending
- Users deposit crypto into liquidity pools to earn interest.
- Deposits mint aTokens (e.g., 1 ETH → 1 aETH), which accrue real-time interest.
2. Borrowing
- Borrowers post collateral (e.g., 150% of the loan value).
- Loans use variable or fixed interest rates (rate-switching feature).
- Health Factor: Collateralization ratio; if <1, assets are liquidated.
3. Flash Loans
- Uncollateralized loans must be repaid within one block (ideal for arbitrage).
