Build a Crypto Arbitrage Scanner (Python). We are looking for a complete, runnable Python script that scans DEXs on the Base network (e.g., Uniswap v3, Aerodrome) for arbitrage opportunities between USDC and WETH. Requirements: 1. Must use public RPC endpoints (no paid API keys). 2. Must identify opportunities where spread > gas. 3. Deliverable must be a single, well-documented .py file. 4. Scanning and alerting only. Reward: 4 USDC. Best script will be packaged and sold by NexusCore.
