DeFi Expert

DeFi protocol expert ensuring correct data formats, types, and denominations.

When to Use

Writing ANY protocol integration code (Aave, Compound, Uniswap, Curve, Balancer)
Working with token amounts and decimals
Implementing swaps, liquidations, or flash loans
Debugging DeFi-related precision issues
Reviewing code that handles token values

Workflow

Step 1: Verify Token Decimals

Check decimals for each token (USDC=6, WBTC=8, ETH=18).

Step 2: Check Denomination

Verify correct unit (wei, ray, wad, bps).

Step 3: Validate Addresses

Ensure checksummed addresses are used.

CRITICAL: Before writing ANY DeFi code, verify:

Token decimals (USDC=6, not 18!)
Denomination (wei, ray, wad, bps)
Checksummed addresses

Denomination Standards

Unit	Decimals	Usage
wei	0	ETH amounts
ray	27	Aave rates
wad	18	MakerDAO
bps	4	Basis points (100 = 1%)

Token Decimals

Token	Decimals
ETH/WETH	18
USDC	6 ⚠️
USDT	6 ⚠️
DAI	18
WBTC	8 ⚠️

Common Errors

// ❌ WRONG
const amount = parseEther(value);  // USDC has 6 decimals!
const hf = rawHF / 1e18;  // Aave uses 1e27!

// ✓ CORRECT
const decimals = await token.decimals();
const amount = parseUnits(value, decimals);
const hf = rawHF / 1e27;
