Aave allows users to borrow and lend crypto with overcollateralised loans. Here's how it works and how you can earn interest with Aave.
Key Takeaways:
- Aave functions as a decentralised crypto lending platform.
- Users must provide collateral in the form of crypto assets to borrow.
- AAVE, the native token of Aave, can be staked to earn interest.
- Borrowers face the risk of collateral liquidation if its value depreciates beyond a certain threshold.
Introduction to Aave Protocol
Aave is a decentralised cryptocurrency platform that enables users to borrow and lend crypto through smart contracts. These contracts automate the process by enforcing predefined rules for fund distribution, collateral management, and fee assessments.
The platform specialises in overcollateralised loans, requiring users to deposit crypto assets worth more than the desired borrowing amount. This protects lenders from potential losses due to loan defaults and allows the Aave protocol to liquidate collateral if its value declines significantly.
How Aave Operates
Aave was first deployed on the Ethereum blockchain in January 2020, enabling lenders to earn interest paid by borrowers. Instead of directly matching lenders with borrowers, Aave pools deposited crypto assets into liquidity pools, from which assets are lent to borrowers. Aave now operates on multiple blockchains, including Avalanche, Optimism, Polygon, and Arbitrum.
All Aave loans are overcollateralised, ensuring that collateral value exceeds the borrowed amount. Borrowers have no fixed repayment timeline but must repay the loan in the same cryptocurrency borrowed, plus interest.
Smart contracts govern the protocol, automating tasks such as loan term calculations, collateral collection, and cryptocurrency distribution. These contracts eliminate intermediaries, ensuring a decentralised lending environment.
Lending on Aave
For lenders, Aave offers the opportunity to deposit crypto assets into liquidity pools, earning interest paid by borrowers. To lend crypto on Aave:
- Connect your digital wallet to the platform.
- Select from the list of supported assets for deposit.
- Earn interest paid in the same asset.
Supported cryptocurrencies include Ether (ETH), Dai (DAI), Aave (AAVE), USD Coin (USDC), and others, depending on the blockchain network. Deposited tokens contribute to liquidity pools, with interest distributed among depositors.
As a decentralised protocol, Aave transactions occur directly on the blockchain, requiring gas fees for depositing or withdrawing funds. Lenders can withdraw funds and earned interest at any time.
Borrowing on Aave
To borrow cryptocurrency on Aave:
- Deposit collateral onto the platform.
- Select from supported crypto assets for borrowing.
- Borrowed funds are deposited into your connected wallet.
The borrowing amount is capped at a percentage of the collateral value, known as the Loan to Value (LTV) ratio. For example, if a collateral has an LTV of 75%, you can borrow up to 0.75 ETH for every 1 ETH of collateral.
Aave also offers flash loans, which must be repaid within the same blockchain block. These loans incur a 0.09% fee and are ideal for arbitrage opportunities.
Liquidation Risk
If collateral value falls below a specified LTV ratio, Aave may initiate liquidation. Liquidators sell a portion of the collateral to repay the loan, receiving a bonus for their efforts. The liquidation penalty varies by asset.
The AAVE Token
The AAVE token is the native cryptocurrency of the Aave platform, serving multiple purposes:
- Governance: AAVE holders vote on protocol changes.
- Staking: Stake AAVE to earn rewards.
- Fee Reduction: Stakers receive discounts on borrowing fees.
- Incentives: AAVE tokens are distributed to encourage participation.
