DEXes Covered

  • Uniswap V2 (Factory: 0x8909Dc15e40173Ff4699343b6eB8132c65e18eC6)

  • Uniswap V3 (Fee tiers: 0.05%, 0.3%, 1%)

  • Aerodrome (Volatile + Stable pools)

How It Works

All tools are read-only -- no private key needed. The server queries on-chain pool reserves, uses DEX quoters for accurate pricing, and compares across exchanges to find price discrepancies that could be exploited via flash loans.

Flash profit estimation accounts for:

  • Aave flash loan fee (0.09%)

  • Base gas costs (dynamically estimated)

  • Slippage warning

Sandwich detection uses heuristic analysis of Swap events to identify same-block multi-transaction patterns from single addresses.
