AI Summary

This is an automated trading bot for Polymarket prediction markets. It runs on Polygon blockchain and offers two trading modes: (1) Arbitrage mode that automatically posts buy orders on both sides of recurring 5-minute BTC markets, waits for favorable prices, merges matched positions, and redeems winnings after markets resolve; (2) Copy trading mode that monitors a target wallet's activity and automatically mirrors their buys with configurable sizing and risk caps. The bot includes built-in circuit breakers, spend limits, and graceful shutdown handling to manage risk during live trading.

How It Works

1
🔍 You hear about automated trading on Polymarket

You discover a tool that can automatically trade 5-minute BTC markets on Polymarket, both by running its own strategy and by copying successful traders.

2
💼 You connect your crypto wallet

You set up a dedicated wallet with USDC on Polygon and link it to your Polymarket account so the bot can trade on your behalf.

3
⚙️ You choose how you want to trade

You pick between letting the bot find its own trading opportunities (arbitrage mode) or automatically copying trades from a wallet you admire (copy trading mode).

4
🚀 You launch the bot and watch it work

With your limits set safely, you start the bot and watch as it automatically places orders, monitors prices, and executes trades around the clock.

5
🔒 Built-in safety guards protect your money

The bot automatically stops if prices move too far, limits how much it can spend per market, and tracks your losses to prevent runaway trading.

6
💰 Your positions get settled automatically

When markets close, the bot cancels any remaining orders, merges matched positions back to cash, and redeems your winnings from the blockchain.

✅ Your trading runs while you sleep

The bot handles the full trading cycle automatically—from market discovery through order placement, merging, and redeeming—while you monitor the results in your logs.

AI-Generated Review

What is Polymarket-trading-bot?

A Node.js trading bot for Polymarket that runs on Polygon and executes arbitrage on short-duration BTC markets. It posts dual-sided orders, watches the order book via WebSocket, and automatically merges and redeems positions. A separate copy-trading module mirrors wallet activity in real time.

Why is it gaining traction?

Developers want ready-made infrastructure for trading on Polymarket without building from scratch. This bot handles the messy parts: CLOB authentication, EIP-712 order signing, on-chain approvals, and circuit breakers. The copy-trading path is particularly useful because it polls the public trade feed and fires orders with configurable caps and slippage filters. Having both arbitrage and copy-trading in the same repo lowers the barrier to experiment.

Who should use this?

Developers with Polymarket accounts and Polygon wallets who want to automate short-duration BTC Up/Down trading. Researchers testing hypothesis-driven strategies on crypto markets will benefit from the structured PnL tracking. Operators running copy-trading setups on Reddit or Discord will find the dedicated entry point practical for mirroring target wallets without touching the arb logic.

Verdict

The credibility score is 0.699999988079071%, and with 172 stars the repo shows early traction but limited third-party validation. Documentation is detailed and the codebase follows conventions, but there is no test suite visible. Start with conservative spend limits, a private RPC, and dry-run mode before committing capital.
