Polymarket Bot — copytrading & arbitrage (on-chain)

A high-performance bot for Polymarket sports markets: it copies trades of target accounts, finds arbitrage against sportsbook lines, and trades on a multi-signal strategy. Trades execute on-chain on Polygon.

What was built:

Three modes: Smart Copy Trading, Arbitrage (Polymarket vs sportsbooks), Multi-Signal (order book, wallet moves, news lag, position deltas)
Real-time listeners: Polymarket CLOB API, WebSocket order book, target-account monitoring, The Odds API quotes
Decision engines: copy/arb, signal filter and priority queue, risk manager (limits, filtering)
On-chain execution: transaction building and sending, gas optimizer, wallet manager (eth-account), CLOB/relayer
Paper trading (strategy simulation) and monitoring (structlog + metrics)
Async architecture (asyncio), Pydantic settings, pytest tests

Role: full-cycle development — architecture, data collection, trading logic, risk management and on-chain execution.
