Aave AAVE
The ghost teller who keeps your idle coins working while you sleep
๐ญ You walk up, hand over your coins, and either collect interest or borrow against them. No teller window, no paperwork, no closing hours.
๐ฌ "Drop your coins in the pool and they start earning while you do other things. Need cash but don't want to sell? Put up some coins, borrow against them, pay me back later. I never close. ๐ป"
- What it feels like to use: you deposit coins and watch interest tick up, or you borrow against coins you'd rather not sell. No bank, no application form.
- The catch you'll actually feel: every transaction runs on top of Ethereum, so on a busy day the gas fee can sting before you've earned a cent.
- 'Aave' is Finnish for 'ghost', and it lives up to it: no office, no person, just a contract that's always awake.
๐ The Story
Picture your first time. You've got some ETH sitting in a wallet doing absolutely nothing, and a friend mentions you can lend it out for interest without a bank. You connect your wallet, click Supply, approve a transaction, and a few seconds later there it is: a little number that grows in real time. That's the whole experience. Nobody asked your name. Nobody ran a credit check.
The ghost wasn't always this smooth. It started in 2017 as ETHLend, built by a Finnish law student named Stani Kulechov, and back then it tried to match you one-to-one with a single lender. You could be stuck waiting for someone whose terms lined up with yours. In January 2020 it rebranded to Aave and threw everyone into shared pools instead, which is why borrowing now feels instant rather than like a dating app.
Borrowing is where it gets real. Say you hold ETH but need stablecoins for something and don't want to sell. You deposit the ETH as collateral, borrow against it, and walk away with cash you can spend. The price you pay for that convenience is constant vigilance: the ghost is watching your collateral, and if it falls too far, it sells. There's also the flash loan, a loan you take out and repay inside one block, but unless you write code, you'll never touch it. It's a tool for developers, not for you. ๐ป

๐งฉ How it works
The heart of Aave is one big pool (a liquidity pool). People who hold coins deposit them into the pool and earn interest. People who need coins put up collateral worth more than they borrow (this is called 'over-collateralized lending') and take coins out of the pool. The ghost librarian drifts between them, gathering up the interest and sharing it out. All of it is handled automatically by smart contracts on Ethereum.
๐ Light & Shadow
- Your idle coins start earning the moment you deposit, and you can pull them back out whenever the pool has the funds. No lockup, no manager to ask
- Borrowing is genuinely fast and private. You put up collateral and the coins are yours in seconds, with no credit check and no questions
- It's been running since 2020 and is the platform most people reach for first (Bloomberg reported it among the largest by deposits in Feb 2025), so you're not the guinea pig
- To borrow $100 you have to lock up more than $100 in coins, and if their price falls too far the ghost sells your collateral without asking. Plenty of people have been liquidated overnight while asleep
- Every click costs Ethereum gas. On a busy day a single deposit can cost more than a week of interest, which quietly eats small accounts alive
- You're trusting code. If a bug slips into the contracts, funds can vanish in a way no bank insurance covers (a risk shared by all of DeFi)
๐งฌ Evolution line
Aave isn't a fork of another coin. Its earlier token LEND was swapped into AAVE at a 100:1 ratio (a migration), a generational handover within the same project. It's a single line from ETHLend (LEND) โ Aave (AAVE), not a fork or a sibling of any other coin.
Aave has no chain of its own and runs on Ethereum. So its transactions are secured by Ethereum's Proof-of-Stake.

โ FAQ
- What is Aave (AAVE)?
- It's a decentralized lending platform that lets you earn interest by depositing crypto, or borrow other coins by putting up your crypto as collateral, all without a bank-like middleman. The name 'Aave' is Finnish for 'ghost'.
- Does it have its own blockchain?
- No. It has no chain of its own, it's a set of smart contracts running on top of Ethereum. So its transactions are secured by Ethereum's Proof-of-Stake.
- What is a 'flash loan'?
- It's an unsecured loan you have to borrow and pay back within the same block. Because it begins and ends in one go, it's mostly used by developers and for arbitrage. Aave is the platform that made flash loans mainstream.
- How many AAVE tokens will there ever be?
- The supply is capped at 16 million (around 15.1-15.2 million circulating today). Like Bitcoin, it has a hard cap, the exact opposite of a coin like Dogecoin, which has no supply limit.
