Aave is a decentralized money market operating on the Ethereum blockchain, enabling users to lend and borrow various cryptocurrencies. Its standout features include diverse crypto loan options and passive income opportunities for lenders.
Key Features of Aave
Algorithmic Money Market
- Introduced during Aave’s 2020 rebranding from ETHLend.
- Uses liquidity pools instead of peer-to-peer matching.
Interest rates adjust algorithmically based on asset supply and demand:
- High demand → Higher rates to incentivize lenders.
- Low demand → Lower rates to encourage borrowing.
Collateralized Loans
- Borrowers must deposit collateral exceeding the loan value (e.g., $12 in crypto for a $10 loan).
- Smart contracts automatically liquidate collateral if its value drops below a set threshold.
AAVE Token
- Grants fee discounts for collateral usage.
- Provides governance rights proportional to holdings.
aTokens
- Interest-bearing tokens (e.g., aDAI for DAI deposits).
- Interest accrues in real time and transfers directly to lenders’ wallets.
Flash Loans
- Uncollateralized loans repaid within one transaction block.
- 0.09% fee; reverts if unpaid.
- Ideal for arbitrage and quick trades.
Rate Switching
- Borrowers can choose fixed or floating interest rates.
- Mitigates market volatility risks.
Use Cases
Decentralized Finance (DeFi)
- Enables global, permissionless lending/borrowing.
- Lenders earn passive income; borrowers access liquidity.

Aave’s open-source protocol supports collaborations like:
- Axie Infinity: In-game Aave rewards and NFTs.
