AI Summary

This is an open-source automated trading bot designed for Polymarket's prediction markets. It connects to your cryptocurrency wallet, watches live prices for UP/DOWN prediction tokens on crypto assets (Bitcoin, Ethereum, Solana, XRP), and automatically buys or sells based on rules you configure. The bot operates on the Polygon blockchain using real funds and offers two trading strategies: one for exiting existing positions and another for full entry/exit trading with optional emergency swaps. It provides real-time status updates showing your portfolio balance, open positions, and market trends.

How It Works

1
🔍 You discover the trading bot

You hear about an automated tool that can trade prediction markets on Polymarket for crypto assets like Bitcoin and Ethereum.

2
⚙️ You set up your trading settings

You choose which cryptocurrency to track (Bitcoin, Ethereum, Solana, or XRP) and how often you want to trade (every 5 minutes to once a day).

3
💼 You connect your wallet

You connect a cryptocurrency wallet that holds USDC on the Polygon network, which the bot will use to place real trades.

4
🚀 You launch the bot

With one click, your automated trading assistant starts watching market prices every second and making decisions for you.

5
The bot watches the market
📈
Strategy 1: Exit only

If you already own prediction tokens, the bot watches for the right moment to sell them before the market closes.

🔄
Strategy 2: Full trading

The bot can both enter new positions and exit them, with an optional safety feature to quickly swap to the opposite prediction.

6
📊 You watch your portfolio grow

On your screen, you see live updates showing your cash, your prediction tokens, and how your positions are performing.

What is polymarket-arbitrage-trading-bot?

This is a TypeScript trading bot for Polymarket's crypto prediction markets. It watches UP/DOWN markets on Bitcoin, Ethereum, Solana, and XRP across timeframes from 5 minutes to 24 hours, then executes configurable strategies automatically using real on-chain balances. The bot polls the order book every second, reads your actual wallet state via the Polymarket CLOB API, and places Fill-and-Kill orders on Polygon. You configure strategy parameters in a TOML file, set your market coin and timeframe, and run it with a single npm command. It is not a backtester or simulator.

Why is it gaining traction?

The hook is live trading with real money on short-duration prediction markets. Most trading bots target longer timeframes or require complex infrastructure. This one gives you a working loop that resolves market slugs, fetches prices, and executes trades with retry logic and balance polling out of the box. The two built-in strategies cover different risk profiles: one exits existing positions, the other enters, exits, and optionally swaps to the opposite side. The configuration is straightforward enough that non-traders can tweak thresholds without touching code.

Who should use this?

Developers interested in building on Polymarket's CLOB will find this a useful starting point. Quantitative traders who want to experiment with short-horizon prediction market strategies without building the plumbing from scratch. It is not suitable for production use without significant validation: the credibility score is essentially zero, there is no visible test suite, and the project has only 79 stars. Treat it as a reference implementation or experimental sandbox, not a turnkey trading system.

Verdict

At 79 stars with a 0.85% credibility score, this is an early-stage experimental project that demonstrates a working Polymarket trading loop. The code is readable and the architecture is sound, but it lacks the maturity, test coverage, and community trust needed for production deployment. Fork it, understand how it works, and extend it with your own risk controls before considering it for live trading.
