Aave has evolved from a decentralized peer-to-peer (P2P) lending model—similar to its predecessor ETHLend—to an innovative pool-based strategy. Here's how it works:
Pool-Based Lending Mechanism
- Liquidity Provision: Lenders deposit cryptocurrencies into a shared pool contract, earning interest.
- Collateralized Borrowing: Borrowers access funds from the same pool by locking collateral, eliminating the need for direct lender-borrower matching.
- Instant Loans: Loans are processed immediately based on real-time pool liquidity and collateral ratios, offering flexibility unmatched by traditional P2P systems.
Unique Features of Aave
1. Flash Loans: Collateral-Free Borrowing
Aave revolutionized DeFi with flash loans, which require no collateral if repaid within a single blockchain transaction block.
How It Works:
- The loan is issued only if the borrowed amount (plus fees) is returned before the transaction ends. Otherwise, the entire transaction reverts, ensuring no risk to the pool.
Use Cases:
- Arbitrage: Exploit price differences across exchanges.
- Refinancing: Avoid liquidation penalties (e.g., repaying a MakerDAO loan before collateral drops below threshold).
- Liquidation: Capitalize on undercollateralized positions for profit.

2. Rate Switching: Fixed vs. Floating Interest Rates
Aave allows borrowers to toggle between fixed and variable interest rates, hedging against market volatility.
Key Scenarios:
- Locking Rates: Switch to fixed rates if an increase is anticipated.
Auto-Adjustments:
- If deposit rates exceed fixed borrow rates, the system rebalances to maintain stability.
- If variable rates drop 20% below fixed rates, the loan automatically adjusts downward.
