What is Aave?
Aave is a decentralized lending protocol: you can deposit crypto to earn interest, or post crypto as collateral to borrow other assets, all through smart contracts rather than a bank. AAVE is the governance token that votes on how the protocol is run, and the Aave DAO uses protocol revenue to buy AAVE on the open market.

What Aave actually does
Runs pooled lending markets where depositors earn interest and borrowers take over-collateralized loans; AAVE governs risk settings and the treasury.
- Real-world usage
- establishedAave has been one of the largest DeFi lending protocols for several years, with deposits and loans across many networks.
- Token necessity
- optionalYou can lend and borrow on Aave without holding AAVE; the token is used for governance, safety staking and buybacks.
- Decentralization
- moderateLending runs on public contracts and decisions go through on-chain DAO votes, but voting power is concentrated and service providers such as Aave Labs and risk firms shape most proposals.
- Track record
- longAave grew out of ETHLend (2017) and launched its pooled protocol in January 2020; it has absorbed episodes of bad debt but has no major core-contract hack on record.
What it’s used for
Depositors supply assets such as stablecoins or ETH to earn variable interest, and borrowers use those deposits as collateral to take loans, often to avoid selling. Aave operates markets on Ethereum and many other networks, and it also issues its own stablecoin, GHO. AAVE holders vote on new markets, collateral rules and treasury spending.

How Aave works
Aave pools deposits from many users into markets. When you deposit, you receive a token that tracks your balance plus interest. Borrowers must post collateral worth more than they borrow, and interest rates float with demand: the more of an asset is borrowed, the higher its rate. If a borrower's collateral value falls too far, anyone can repay part of the loan and claim some collateral at a discount. This is called liquidation, and it keeps the pools solvent.
AAVE is the governance token. Holders and stakers vote on which assets can be used, how much can be borrowed against them, interest rate settings and new deployments. Part of the interest borrowers pay goes to the DAO treasury, and governance has directed some of that revenue into an ongoing AAVE buyback program. A safety layer called Umbrella lets stakers earn rewards in exchange for having their stake used to cover bad debt if losses occur.
In 2026 Aave began rolling out V4, which reorganizes liquidity into central hubs connected to specialized spokes, such as a market for a single stablecoin or for correlated assets. Earlier versions remain live, and many apps, wallets and institutions connect to Aave behind the scenes. Aave Labs, the company that originally built the protocol, also offers a consumer savings app, and its relationship with the DAO over brand and revenue has been debated publicly.
Key moments
- 2017The project launches as ETHLend, a peer-to-peer lending platform.
- 2020Aave v1 pooled lending launches in January; the LEND token migrates to AAVE and on-chain governance begins in October.
- 2023Aave launches GHO, its own over-collateralized stablecoin.
- 2025AAVE buybacks start in April and the Umbrella safety system goes live in June.
- 2026Aave V4 launches on Ethereum mainnet in March, followed by Avalanche and Arc.
Supply
AAVE has a maximum supply of 16 million tokens, most of which are already in circulation. There is no ongoing inflation schedule; the DAO uses part of protocol revenue to buy AAVE on the market, and holders can stake AAVE in safety programs for rewards.
Risks to understand
- Liquidation risk: if your collateral drops in value, part of it can be sold off at a discount to repay your loan.
- Bad debt and oracle risk: sharp price moves or faulty price feeds can leave loans undercollateralized, with losses absorbed by safety stakers or the treasury.
- Smart-contract risk across many versions and networks, including the new V4 code.
- Governance and organizational risk: disputes between Aave Labs and DAO members over fees and brand control show that key decisions can be contested.
- Exposure to listed assets: a stablecoin depeg or a failing collateral token can ripple through the markets that accept it.
Aave FAQ
Do I need AAVE to lend or borrow?
No. You supply and borrow other assets directly. AAVE is used for voting, safety staking and the DAO's buyback program.
Where does the yield on Aave come from?
Depositors are paid from the interest borrowers pay. Rates change constantly with supply and demand, so the yield is not fixed or guaranteed.
What is GHO?
GHO is a dollar-pegged stablecoin issued by the Aave protocol and backed by collateral that borrowers lock in Aave.
What changed with Aave V4?
V4 reorganizes liquidity into shared hubs connected to specialized markets called spokes. It launched on Ethereum in March 2026 while earlier versions keep running.
