DeFi Yield Scanner

Autonomous scanner for DeFi yield opportunities across 10+ protocols.

What It Scans

Aave v3 (Polygon, Arbitrum, Base): supply APY, borrow APY, utilization rate

Compound v3: USDC/USDT supply rates, COMP reward APR

Curve Finance: stable pools, CRV emissions, gauge weights

Uniswap v3: fee tier APY for concentrated liquidity positions

Yearn Finance: vault APY including harvesting strategy returns

Yield Ranking

Each opportunity is scored on: 1. APY (raw + adjusted for token emissions) 2. Risk (smart contract age, audit status, TVL) 3. Sustainability (emission-adjusted vs organic APY) 4. Gas efficiency (on Polygon/L2 vs mainnet)

How to Use

Ask: *"Find the best stable yield on Polygon right now"* or *"Compare USDC yields across Aave, Compound, Curve"*

The agent fetches live APY data, applies risk filters, and returns ranked opportunities with entry instructions.

Data Sources

DeFiLlama API (api.llama.fi) — TVL, APY, protocol metadata

Aave subgraph (The Graph)

Curve registry (curve.fi/api)

Yearn vaults API (yearn.fi/api)
