Aave (AAVE) – A DeFi Platform for Crypto Lending & Borrowing
Aave is a decentralized finance (DeFi) platform primarily on Ethereum. It allows users to take out instant crypto loans using their crypto as collateral.
It also enables users to lend out their crypto to earn returns. Aave was created by coders led by Stani Kulechov and launched in November 2017 as ETHLend.
It rebranded to its current name (meaning “ghost” in Finnish) in September 2018. As of writing, Aave has over $6 billion in total value locked across all chains.1

What is Aave?
Aave is a decentralized finance (DeFi) lending protocol. Users can borrow and lend cryptocurrencies without intermediaries. Smart contracts automate lending and borrowing processes.
A Decentralized Finance (DeFi) Lending Protocol
Aave enables peer-to-peer lending and borrowing.2 Lenders deposit digital assets into liquidity pools. Borrowers must overcollateralize their loans for security.
Aave’s Rebranding: From ETHLend to Aave
Originally launched as ETHLend in 2017. It was a peer-to-peer lending marketplace. Rebranded to Aave (“ghost” in Finnish) in 2018.
How Does Aave Work?
Aave is a decentralized financial system. It allows lending and borrowing digital assets without central authority.2 Lenders deposit assets into liquidity pools. These pools provide loans to borrowers.2 Borrowers must overcollateralize loans, providing more collateral than borrowed amount.
Lending and Borrowing in Decentralized Finance
Aave’s lending is based on overcollateralized loans. Borrowers deposit more collateral than borrowed amount.2 This protects lenders from loan defaults. Smart contracts facilitate lending and borrowing activities.2 These self-executing contracts trigger transactions when conditions are met.
Over-collateralized Loans and Smart Contracts
Aave limits borrowing to 80% of collateral’s value.2 Loans are overcollateralized, ensuring collateral’s value exceeds loan value.2 This safeguards lenders, reducing default risk.
Aave’s Liquidity Pools and aTokens
Lenders deposit assets into liquidity pools. These smart contracts aggregate deposits per asset.2 Borrowers access these pools for loans. Lenders receive aTokens representing their pool share.2 aTokens allow earning interest on deposits.
Aave supports lending and borrowing various cryptocurrencies. These include Ether, Dai, Aave, USDC, and Tether.2 Users can participate in DeFi by lending, borrowing, and earning interest.
| Aave Feature | Description |
|---|---|
| Loan-to-Value (LTV) Ratio | Borrowers risk liquidation if collateral value drops below LTV ratio.2 |
| Fees | 0.09% fee for Flash Loans.2 2% to 30%+ APY variable/fixed loan fees.2 |
| User Funds Protection | No insurance, user funds unprotected.2 |
| Lender Earnings | Users earn interest on deposits in deposited asset.2 From interest collected on borrower loans.2 |
Aave (AAVE) – A DeFi Platform That Enables Lending and Borrowing of Cryptocurrencies
Aave is a decentralized platform. It allows users to supply crypto assets and earn interest. Users can also borrow crypto assets using their assets as collateral.
Aave’s platform runs on smart contracts. These automate lending and borrowing without a central intermediary. The platform offers flash loans, liquidity mining, and yield farming.
For borrowing, users must deposit overcollateralized loans. This means depositing more collateral than the borrowed amount. Aave limits borrowing to 80% of the current collateral value. This approach ensures a secure and transparent way for cryptocurrency lending and borrowing.
Aave offers flash loans – instant, collateral-free loans. These must be repaid in the same transaction. Flash loans allow taking advantage of arbitrage opportunities. Aave charges a 0.09% fee for flash loan transactions.
The AAVE governance token allows holders to participate in decision-making. This shapes the protocol’s future. As of 2022, Aave has over $10 billion deposited, making it a major decentralized finance platform.
In summary, Aave enables secure, decentralized cryptocurrency lending and borrowing. Its innovative features like flash loans and governance token contribute to its recognition as a leading decentralized finance protocol.
Aave’s Lending Process
The Aave platform enables users to lend cryptocurrency assets. They deposit assets into liquidity pools. These pools provide funds for borrowers. Lenders earn interest on deposited assets.2
Depositing Crypto Assets into Liquidity Pools
To lend on Aave, users deposit cryptocurrency into liquidity pools. The pools aggregate deposits for different assets. These aggregated deposits are used for borrower loans.3
Earning Interest on Lent Assets
Lenders earn interest on crypto deposited into Aave liquidity pools. Interest rates are algorithmically determined by asset supply and demand. As borrowers pay interest, a portion goes to lenders.2
| Key Aave Lending Statistics | Value |
|---|---|
| Total Value Deposited in Aave | Over $10 billion as of 20224 |
| Staking Yields on AAVE Token | Up to 10%4 |
| Minimum Staked AAVE Lockup Period | 7 days4 |
| Aave Supported Blockchain Networks | Over 104 |
Aave’s Borrowing Process
The lending process on Aave starts with users providing crypto assets as collateral. The borrowable amount is limited by the collateral value. Aave requires over-collateralization to protect lenders from loan default losses.2
Providing Collateral for Borrowing
To borrow on Aave, users must supply their crypto assets as collateral. Aave limits the borrowed amount to 80% of the current collateral value.
This over-collateralization model ensures lenders are safeguarded against potential loan defaults.2
Loan-to-Value (LTV) Ratio and Liquidations
Aave uses the Loan-to-Value (LTV) ratio to determine the maximum borrowable amount. If the collateral value drops below a certain LTV, Aave can automatically liquidate a portion to repay the loan.
Liquidations involve selling up to 50% of the pledged collateral to pay back the loan if its value drops below a certain LTV.2
Aave charges borrowing fees ranging from 2% to 30%+ annual percentage yield (APY) or more. Interest on loans is paid to lenders in the form of the deposited crypto assets.2
Flash Loans and Governance
Aave offers a special feature: “flash loans.”5 These loans don’t need collateral.5 They must be repaid quickly.
Flash loans let developers take advantage of opportunities.5 They use Ethereum’s blockchain for transactions.5 Transactions are accepted or rejected entirely.5
Aave’s Flash Loan Functionality
Aave charges a 0.09% fee for flash loans.5 Only developers with coding skills can use them.5
Users borrow tokens from lending pools.5 They execute loan parameters on Ethereum.5 They repay the loan plus fees in one transaction.5
Flash loans enable unique use cases.5 For example, swapping volatile assets for stablecoins.5 Or exchanging debt currencies for better rates.5
The AAVE Governance Token
Aave launched its AAVE governance token in 2020.1 AAVE holders vote on protocol decisions.1 For example, adding assets to lending markets.1
AAVE holders can stake tokens for rewards.1 This helps secure protocol reserves.1 AAVE is used for governance and incentives.4
AAVE holders get rewards for participating.4 They also get lower borrowing fees.4
Conclusion
Aave stands out as a trailblazer in decentralized finance (DeFi). With over $10 billion deposited in 20224, it’s a leading crypto lending and borrowing platform.
Smart contracts and over-collateralized loans let Aave function without middlemen. Users gain autonomy over their crypto finances.
Innovative features like flash loans and AAVE governance token solidify Aave’s influence. It evolves to meet crypto community’s growing needs.46
