What Is Aave?
Aave (Finnish for "ghost") is an Ethereum-based DeFi protocol that expanded to chains like Avalanche and Polygon. Launched in 2017 as ETHLend, it eliminates intermediaries by using smart contracts for deposits, loans, and liquidations. Unlike centralized platforms, Aave requires no KYC checks and offers full user control over funds.

Core Features of Aave
1. Deposits & aTokens
- Deposit assets (e.g., DAI) to receive aTokens (e.g., aDAI).
- aTokens accrue interest in real time and can be traded or redeemed.
2. Borrowing Options
- Variable rates: Adjust dynamically based on pool utilization.
- Fixed rates: Lock in predictable costs.
- Loan-to-Value (LTV): Varies by asset (e.g., 75% for ETH).
3. Flash Loans
- Uncollateralized loans repaid within one transaction block.
- Ideal for arbitrage or refinancing.
4. Risk Management
- Liquidation: Triggered if collateral value falls below threshold (5% fee applied).
- Safety Module: Staked AAVE tokens act as a backstop for system losses.
The AAVE Token
Aave’s governance token empowers holders to vote on protocol upgrades. Benefits include:
- Higher borrowing limits when used as collateral.
- Staking rewards via the Safety Module.
- Note: Distinct from aTokens (proof-of-deposit receipts).
