Aave Protocol, with its native token $LEND, is a leading player in decentralized finance (DeFi). It enables users to access open-source, non-custodial protocols for creating money markets.
Understanding Aave
Aave is a decentralized finance (DeFi) protocol allowing users to lend and borrow cryptocurrencies and real-world assets (RWAs) without centralized intermediaries. Lenders earn interest, while borrowers pay interest.
Initially built on Ethereum, all tokens used the Ethereum blockchain (ERC-20 standard). Aave has since expanded to networks like Avalanche, Fantom, and Harmony.
History of Aave
Founded in September 2018 after a successful 2017 initial coin offering (ICO) for ETHLend, which raised $16.2 million. The team migrated to Aave, making ETHLend a subsidiary. By January 2020, ETHLend ceased operations, though its website remained active for closing existing loans.
Aave aimed to bridge gaps left by centralized fintech giants like PayPal and Coinbase. Its flagship product, the Aave Protocol, launched in January 2020, shifting from peer-to-peer lending to a pool-based strategy.
How Aave Protocol Works
The protocol creates decentralized money markets on Ethereum:
- Depositors provide liquidity by adding crypto to lending pools, earning interest.
- Borrowers access loans from these pools, either with collateral (secured) or without (flash loans).
Loans don’t require 1:1 lender-borrower matching. Instead, pool liquidity and collateral ratios determine instant loans.
Two primary markets exist: Aave and Uniswap.
Key Lending Features
1. Flash Loans
Unique to Aave, these uncollateralized loans allow smart contracts to borrow assets in one transaction, repaid before the transaction ends. If unpaid, the transaction reverts.
Use cases: Arbitrage, refinancing, liquidation.
Fee: 0.09%.
2. Rate Switching
Borrowers toggle between fixed and variable interest rates—ideal for volatile markets.
- Fixed rates suit stable conditions but rebalance if deposit rates exceed loan rates.
- Variable rates auto-adjust if they fall 20% below fixed rates.
Supported Tokens
Aave supports 30+ tokens, including:
- Stablecoins: DAI, USDC, USDT
- Cryptocurrencies: ETH, BAT
- Others: Binance USD (BUSD), sUSD
Each has unique collateral requirements based on price volatility.
The LEND Token
$LEND (formerly ETHLend) is Aave’s native ERC-20 token. Key utilities:
- Fee Reductions: Platform fee discounts.
- Governance: Voting on Aave Improvement Proposals (AIPs).
- Safety: Token holders act as first-line defense in liquidity events, earning protocol fees.
