What is polymarket-sports-copy-trading-bot?

This TypeScript bot automates copy trading on Polymarket's sports markets by monitoring a target wallet's BUY trades via REST API or WebSocket, then executing scaled copies using the Polymarket TypeScript CLOB client. It handles auth via EOA, proxy, or safe wallets, generates API keys from your seed phrase, and applies user-defined position multipliers, slippage tolerance, and order types like FOK or LIMIT. Developers get a ready-to-run script that reconciles positions, skips SELLs for safety, and enforces risk controls like max session or per-market notional caps.

Why is it gaining traction?

It stands out with real-time WebSocket monitoring for low-latency copies, flexible auth options beyond basic EOA, and built-in safeguards like market price guards and balance checks that prevent blowups. The .env-driven setup auto-generates Polymarket TypeScript API creds, supports neg-risk markets, and retries failed orders intelligently—saving hours versus building from the Polymarket TypeScript SDK scratch. At 41 stars, it's pulling devs who want plug-and-play CLOB bot controls without wrestling raw APIs.

Who should use this?

Quantitative traders mirroring sharp sports bettors on Polymarket, DeFi bot builders testing copy strategies on Polygon, or solo devs automating wallet-following without custom infra. Ideal for those with USDC on Polygon needing quick risk-managed execution, but skip if you're building production HFT.

Verdict

Grab it for prototyping Polymarket copy bots—functional TypeScript with solid CLOB integration—but its 0.7% credibility score and 41 stars signal early-stage maturity; expect tweaks for reliability and add your own tests. Worth forking if copy trading fits your playbook.
