What Is Aave and How Do Flash Loans Work on It?
Charlotte Parent2 min read·Just now--
Aave is one of the most important protocols in DeFi. It is also where most flash loan activity happens. Understanding Aave is essential for anyone serious about DeFi income strategies.
What Is Aave?
Aave is a decentralized lending protocol. It connects people who want to earn interest on their crypto with people who want to borrow crypto. No bank. No intermediary. Just smart contracts running automatically on Ethereum and several other networks.
Depositors earn interest. Borrowers pay interest. The protocol takes a small cut. Everything runs automatically based on rules encoded in smart contracts.
Aave's Key Numbers (2026)
- Over $10 billion in total value locked
- Available on Ethereum, Arbitrum, Optimism, Polygon and more
- Supports dozens of assets including ETH, WBTC, USDC, DAI
- Flash loan fee: 0.09% of borrowed amount
How Flash Loans Work on Aave
Aave’s liquidity pools hold assets deposited by lenders. Flash loans temporarily borrow from these pools within a single transaction.
The process:
- You request a flash loan specifying the asset and amount
- Aave transfers the funds to your smart contract
- Your contract executes whatever strategy you have programmed
- Your contract repays Aave the borrowed amount plus 0.09% fee
- If repayment succeeds, transaction completes. If not, everything reverts.
Why Aave Is the Go-To Platform
Aave has the deepest liquidity, the most supported assets, and the most battle-tested smart contracts. When something is worth billions of dollars and has been running for years without a major exploit, that matters.
