How Aave Works
Lending and Borrowing Mechanics
- Liquidity Pools: Users deposit assets into pools, earning interest based on supply/demand.
- Collateralized Borrowing: Borrowers provide collateral (e.g., ETH) to secure loans in other assets.
- Variable Rates: Interest rates adjust dynamically, optimizing returns for lenders and costs for borrowers.
Flash Loans
- No Collateral Required: Borrow assets instantly for arbitrage or trades, repaid within one transaction.
- Use Cases: Ideal for advanced traders exploiting short-term market inefficiencies.
Security Measures
- Smart Contracts: Automate transactions and collateral management.
- Safety Module: AAVE tokens backstop potential losses from market shocks or exploits.
Core Features of Aave
Token Swaps
- Swap tokens directly on Aave, avoiding external exchanges and fees.
Gas Optimization
- Batched transactions and gas refunds reduce Ethereum network costs.
Governance
- AAVE token holders vote on protocol upgrades, fee structures, and risk parameters.
aTokens
- Interest-bearing tokens (e.g., aETH) auto-accrue rewards, redeemable 1:1 for underlying assets.
