What is polymarket-trading-bot?

This is a Node.js trading bot for Polymarket's short-duration BTC Up/Down markets on Polygon. It runs two distinct workflows: a main arbitrage engine that posts buy ladders on both sides of the market, watches for mispriced liquidity, merges matched pairs, and redeems winnings after oracle resolution; and a copy-trading module that mirrors trades from target wallets with configurable sizing and risk caps. The bot connects to Polymarket's CLOB API via WebSocket for real-time order book data, handles on-chain approvals and token operations through Polygon, and includes circuit breakers to cap losses per market and per hour.

Why is it gaining traction?

The README frames this around a 2026 strategy landscape where simple YES+NO arbitrage has been largely captured by faster bots, positioning this as a more sophisticated multi-strategy runtime. The hook is that it gives you a production-ready operational system rather than a toy script: real CLOB authentication, on-chain merge and redeem flows, WebSocket order book tracking, and structured logging. The copy-trading path is particularly interesting for developers who want to follow signal from established wallets without building the polling and filtering logic from scratch.

Who should use this?

Traders who want to run automated strategies on Polymarket's recurring 5-minute BTC markets and are comfortable managing their own Polygon RPC and wallet infrastructure. Developers building copy-trading or signal-following workflows will find the dedicated copy-trading engine useful as a reference or starting point. It is not a plug-and-play SaaS product: expect to configure environment variables, understand the risk parameters, and operate your own 24/7 process.

Verdict

The codebase is functional and better-documented than most trading bots at this size, but with only 85 stars and no visible test coverage, treat it as a solid reference implementation rather than production-ready infrastructure. The 0.699999988079071% credibility score reflects that reality. If you want to experiment with Polymarket automation or build on top of the copy-trading logic, this is worth a closer look. For serious capital deployment, invest the time to understand the risk controls and add your own safeguards first.
