AI-Generated Review

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

This TypeScript Polymarket copy-trading bot mirrors buy orders from a target wallet on sports and crypto prediction markets via the Polymarket TypeScript CLOB client. It polls the data API or subscribes to WebSockets for real-time trade detection, sizes copies based on a multiplier with min/max limits, and executes FOK, FAK, or limit orders using your Polygon wallet. Users get automated trading with EOA or proxy/safe auth, plus buy-only mode to avoid sells.

Why is it gaining traction?

It stands out with dual REST/WebSocket monitoring for low-latency detection, built-in risk caps on session and per-market exposure, and simple env config for slippage, order types, and position sizing—no complex setup needed. Devs like the Polymarket TypeScript API integration and credential generation commands, making it a quick drop-in for copy-trading bots versus manual scripting. At 19 stars, it's niche but hooks experimenters tired of building from scratch.

Who should use this?

Prediction market traders copying pro wallets on Polymarket sports events, or quant devs automating mirror strategies on Polygon. Ideal for TypeScript GitHub projects needing a Polymarket TypeScript SDK base, like bots for EOA flows or CLOB order routing. Skip if you're risk-averse or need sell mirroring.

Verdict

Grab it for small-scale testing—solid docs and CLI like `npm start` or `npm run generate-api-creds` make it approachable, but with 19 stars and no audits, treat as educational (credibility score: 0.70%). Start with tiny sizes; production needs your own review.
