AI Summary

An open-source trading bot that automatically buys and sells cryptocurrency prediction market contracts on Polymarket. The bot watches live prices for crypto markets like Bitcoin and Ethereum, follows your chosen strategy rules, and executes real trades using your funds on the Polygon blockchain. You configure it with your wallet and preferred trading approach, then let it run continuously to trade on your behalf whenever market conditions match your settings.

How It Works

1
🔍 You discover the bot online

You find an open-source trading tool that promises to automatically trade crypto prediction markets on Polymarket for you.

2
📋 You set up your wallet connection

You prepare your cryptocurrency wallet that holds USDC on Polygon and connect it to the bot so it can make trades on your behalf.

3
⚙️ You choose your trading style

You pick between two trading approaches: one that only sells when you already have a position, or one that can both enter and exit positions with an emergency swap option.

4
🚀 You launch the bot

With one command, your trading assistant starts watching crypto prices every second and waits for the right moment to act.

5
👀 The bot watches the market

Your assistant continuously checks live prices and calculates when conditions match your chosen strategy.

6
The strategy triggers an action
📈
Buy a position

Your bot spends USDC to purchase either an UP or DOWN token depending on which direction it predicts

📉
Sell a position

Your bot converts your held tokens back to USDC to lock in your results

🎉 Your trades execute automatically

The bot places real orders on the Polymarket exchange, and you can watch your portfolio update as it buys, sells, and responds to market movements throughout the trading window.

AI-Generated Review

What is polymarket-arbitrage-trading-bot?

This is a TypeScript-based automated trading bot for Polymarket's crypto prediction markets. It polls real-time prices from the CLOB API every second, monitors your on-chain USDC balance and positions on Polygon, and executes configurable buy/sell strategies on short-horizon BTC, ETH, SOL, and XRP UP/DOWN markets. You configure strategy rules and trade sizing in a TOML file and run it with a single command.

Why is it gaining traction?

The bot directly queries live Polymarket data and executes against real wallets—no paper trading or backtesting simulation. Two built-in strategies handle exit-only and entry-with-emergency-swap logic, with configurable time and price thresholds. Authentication supports both EOA and proxy wallet signatures with automatic fallback, which covers most wallet setups out of the box.

Who should use this?

Developers comfortable with Node.js and Ethereum tooling who want to run automated execution on Polymarket's 5-minute to 24-hour prediction markets. Not suitable for beginners—understanding of on-chain USDC, private key management, and Polymarket's CLOB is required. Ideal if you want to fork and customize strategy logic rather than build from scratch.

Verdict

This is a functional, real-money trading tool that gets you from zero to live bot execution in under 15 minutes. However, with only 82 stars and a credibility score of 0.699999988079071%, the codebase lacks the community scrutiny and maturity you'd want before trusting it with significant capital. Start with the minimum viable trade size, review the TOML thresholds carefully, and test against a funded wallet with limited balance before scaling up.
