エグゼクティブサマリー

仕組み・プロトコルアーキテクチャ
Liquidity Pools & Interest Rate Algorithms
Lenders deposit assets into liquidity pools and receive interest-bearing aTokens (e.g., aUSDT) that accrue yield in real-time.
Borrowers access loans by supplying excess collateral. Interest rates adjust dynamically based on pool utilization ratios.
Flash Loans & Safety Module
Aave pioneered Flash Loans—uncollateralized borrowing that must be borrowed and repaid within the exact same block execution.
The Aave Safety Module enables token holders to stake AAVE to backstop protocol insolvency risks while earning protocol incentives.
