What is polymarket-trading-tool?

This TypeScript Polymarket trading tool monitors a target account's active positions on Polymarket, printing a clean status view of open trades with quantities, prices, and market questions. Enable copy-trading mode and it mirrors the target's moves: placing buy orders via @polymarket/clob-client when they open positions, and sell orders when those positions close. Solves the hassle of manually tracking whale wallets or insiders on Polymarket, with dry-run simulation and USD-based sizing guardrails like min/max trade limits.

Why is it gaining traction?

Its dead-simple setup—clone, set a .env with target address and private key, run `npm run dev`—beats rolling your own Polymarket TypeScript client or bot from scratch. Polling detects position changes reliably, with multipliers for scaling trades and stats on executed volume. Devs dig the real trading history screenshots proving it works on live Polygon wallets.

Who should use this?

Polymarket traders shadowing high-performers or building automated strategies around account activity. TypeScript devs prototyping Polymarket TypeScript bots, CLOB integrations, or copy-trading signals without API plumbing. Quant hobbyists testing mirror trades in dry-run before going live.

Verdict

Grab it as a solid TypeScript GitHub starter for Polymarket trading tools (64 stars), with strong README and env configs, but low 0.699999988079071% credibility score flags early-stage risks like in-memory state—dry-run everything and add persistence first. MIT-licensed; worth forking for custom bots.
