How Aave Lending Works

Aave uses an algorithmic interest rate model where rates adjust based on supply and demand for each asset.

For Lenders (Suppliers)

  • Deposit assets (ETH, USDC, WBTC, etc.) into Aave pools
  • Receive aTokens (aUSDC, aETH) that accrue interest in real-time
  • Earn 7.8% average APY from borrower interest payments
  • Withdraw anytime – Aave maintains high liquidity reserves
  • Optional: Use deposits as collateral for borrowing

For Borrowers

  • Deposit collateral (typically 150-200% of loan value)
  • Borrow up to your borrowing capacity
  • Choose between variable (fluctuating) or stable (fixed) rates
  • Maintain health factor above 1.0 to avoid liquidation
  • Repay anytime to unlock collateral

Aave V3: Major Efficiency Improvements

Aave V3 introduced critical features for capital efficiency and risk management:

1. Isolation Mode

Isolates risk for new and volatile assets:

  • New tokens can only be used as collateral in isolated markets
  • Strict debt ceilings prevent excessive leverage
  • Protects main protocol from asset-specific exploits

📊 Related Resources:

2. Efficiency Mode (eMode)

Allows up to 97% LTV for correlated assets:

  • USDC/USDT/DAI stablecoin pairs: 97% LTV
  • ETH/stETH/wstETH liquid staking pairs: 90% LTV
  • Significantly higher capital efficiency for similar assets

📊 Related Resources:

3. Portals (Cross-Chain)

Supply on one chain, borrow on another:

  • Deposit USDC on Ethereum
  • Borrow on Arbitrum with lower gas costs
  • Unified liquidity across all Aave deployments

📊 Related Resources:

💡 Pro Strategy: Use eMode for stablecoin strategies: Supply $10K USDC → Borrow $9.7K DAI → Supply DAI → Loop for 10-12% net APY with minimal liquidation risk.

Multi-Chain Deployment Strategy

Aave operates on 8 blockchain networks, each optimized for different use cases:

🌐 Aave by Chain (TVL)

Ethereum
$5.8B (62%)
Arbitrum
$1.2B (13%)
Polygon
$890M (10%)
Optimism
$680M (7%)
Base
$420M (5%)
Avalanche + Others
$310M (3%)

Chain Selection Guide

  • Ethereum: Highest liquidity, best for large positions ($100K+)
  • Arbitrum: Low gas fees, great for active strategies
  • Polygon: Ultra-cheap transactions, ideal for small amounts
  • Optimism: OP token rewards boost yields 2-3%
  • Base: Newest deployment, high early yields

Flash Loans: Uncollateralized Borrowing

Flash loans are Aave’s innovation allowing instant, uncollateralized loans within a single transaction:

Use Cases

  • Arbitrage: Exploit price differences between exchanges
  • Collateral Swaps: Change collateral without repaying loan
  • Self-Liquidation: Liquidate your own position to save fees
  • Debt Refinancing: Move debt between protocols in one transaction

📊 Related Resources:

Flash Loan Fees

  • Standard fee: 0.09% of borrowed amount
  • Available for all Aave assets
  • Must be repaid in same transaction or reverts

📊 Related Resources:

⚠️ Technical Warning: Flash loans require smart contract development skills. Incorrect implementation can result in transaction failure and gas fee losses.

Safety Module & AAVE Staking

The Safety Module acts as insurance for the protocol:

How It Works

  • Stake AAVE tokens in Safety Module
  • Earn 7-9% APR in AAVE rewards
  • In case of shortfall event, up to 30% of staked AAVE can be slashed
  • Provides economic security for depositors

📊 Related Resources:

Risk vs Reward

Aave has never had a shortfall event requiring Safety Module activation, making it a relatively low-risk way to earn yield on AAVE tokens.

  5. Net APY: 8-12% with managed liquidation risk

Strategy 3: Cross-Chain Yield Arbitrage

  1. Supply on Ethereum (deepest liquidity)
  2. Use Portals to borrow on Arbitrum (lower rates)
  3. Capture 1-2% rate differential between chains
  4. Automate with tools like DeFi Saver
