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

This TypeScript bot automates copy trading on Polymarket by monitoring a target wallet's trades via the Polymarket trading API and CLOB, then mirroring BUY orders on Polygon with a configurable position size multiplier. It solves the hassle of manually tracking and replicating successful traders' sports market bets, handling API key generation from your wallet seed, approvals, and order execution with FOK/FAK/LIMIT types. Users get a ready-to-run script that polls REST endpoints or streams via Polymarket GitHub WebSocket for real-time copies, complete with slippage tolerance and geo token support.

Why is it gaining traction?

It stands out with built-in risk caps on session and per-market notional, position reconciliation, and a market price guard that halts on illiquid conditions, reducing blowup risks absent in basic Polymarket GitHub clones. The auto-cred generation and WebSocket fallback to REST make setup dead simple—no manual SDK fiddling—while supporting EOA, proxy, and polymorphic auth for advanced Polymarket trading strategies. Devs dig the stats logging and graceful retries, turning a fragile script into reliable Polymarket trading software.

Who should use this?

Polygon traders shadowing whale wallets on Polymarket sports events, or quant devs prototyping copy bots without building from scratch on the Polymarket GitHub API. Ideal for those hit by Polymarket trading unavailable errors in restricted regions, needing a bot that bypasses with geo tokens and manages trading fees via efficient orders.

Verdict

Grab it if you're deep into Polymarket trading bots—it's functional out-of-box despite 19 stars and a 0.7% credibility score signaling early maturity with sparse docs and no tests. Fork and audit the seed handling for production; solid base for custom strategies.
