Introduction
Banks have historically solved critical financial needs—portability, security, and liquidity—by acting as intermediaries between lenders and borrowers. Aave revolutionizes this model by leveraging blockchain technology to create a permissionless, non-custodial, and decentralized lending platform.
In this guide, we’ll explore:
- How Aave’s liquidity pools function.
- The mechanics of lending and borrowing crypto.
- Risk management strategies for users.
How Aave Works: Core Concepts
1. Liquidity Pool Infrastructure
Aave operates via lending pools—smart contracts that aggregate deposited funds (e.g., DAI, ETH) and facilitate borrowing. Key features:
- Depositors (Lenders): Earn interest by adding crypto to pools.
- Borrowers: Access loans by collateralizing assets (e.g., ETH for stablecoins).
- Interest Rates: Dynamically adjust based on supply/demand.

2. Permissionless Access
- No credit checks—loans are over-collateralized (e.g., 150% collateral-to-loan ratio).
- Global inclusivity: Anyone with an Ethereum wallet can participate.
3. Non-Custodial Design
- Users retain full control of assets.
- Funds are managed by smart contracts, eliminating intermediaries.
Step-by-Step: Lending and Borrowing on Aave
For Lenders:
- Deposit crypto (e.g., DAI) into a pool.
- Earn interest (APY) in real-time.
- Withdraw anytime, reclaiming principal + accrued interest.
For Borrowers:
- Collateralize assets (e.g., ETH).

FAQs
Q1: Is Aave safe?
Aave’s smart contracts are audited, but risks include:
- Market volatility affecting collateral.
- Smart contract bugs (rare).
Q2: Can I borrow without collateral?
No—Aave requires over-collateralization to mitigate defaults.
Q3: What happens if I’m liquidated?
Your collateral is sold to repay the loan, with a 5–10% penalty fee.
Conclusion
Aave democratizes finance by replacing banks with transparent, algorithmic liquidity pools. While offering higher yields and inclusivity, users must actively manage risks like liquidation.
