What is Polymarket-copy-trading-bot?

This TypeScript bot automates copy trading on Polymarket by monitoring a target wallet's trades via REST polling and WebSocket streams, then mirroring BUY orders to your Polygon wallet using the Polymarket CLOB API. It handles EOA and proxy auth, calculates scaled position sizes, and enforces risk limits like session and per-market caps. Setup is straightforward: configure .env with your private key and RPC, run npm start, and it tracks positions while skipping SELLs by default.

Why is it gaining traction?

With 480 stars on GitHub, this Polymarket copy trading bot repo draws devs seeking low-latency trade detection without building from scratch, blending Polymarket's trading API, websocket feeds, and CLOB client for reliable execution. It outshines basic scripts by adding buy-only safeguards, slippage tolerance, and FOK/FAK/LIMIT orders, plus easy API credential generation. Reddit threads and Telegram bots highlight its edge over Python or Rust alternatives for quick Polygon deploys.

Who should use this?

Crypto traders shadowing high-performers on Polymarket prediction markets, especially those managing USDC.e positions on Polygon without constant screen time. Devs prototyping trading agents or integrating Polymarket SDK features into apps. Polygon users experimenting with clob-based bots who value configurable multipliers and risk checks over manual order placement.

Verdict

Solid starter for Polymarket copy trading bot github projects—grab it if you're testing strategies, but heed the unaudited disclaimer and 0.8% credibility score by starting with tiny sizes like 1-5 USDC. Decent docs and 480 stars signal maturity for experiments, though production needs audits and more tests.
