Aave is one of the largest decentralized lending protocols: users deposit crypto into liquidity "pools" from which others borrow by posting collateral, and interest rates adjust automatically according to the supply and demand of each asset. Everything happens through smart contracts, with no bank in the middle.

When you deposit an asset into Aave you receive an equivalent "aToken" (for example, aUSDC when you deposit USDC), a receipt that represents your deposit and whose balance grows continuously as interest accrues. That aToken can be moved or used in other apps, which turns the deposit into a productive asset rather than a simple locked balance.

Aave popularized "flash loans": uncollateralized loans that must be borrowed and repaid within a single transaction, in one block. If they are not repaid instantly, the whole operation reverts. It is a powerful primitive for arbitrage or refinancing, but also a technical tool that has been used in attacks on other DeFi protocols, a risk inherent to the ecosystem.
