TypeScript
AI Summary

A free, open-source TypeScript program that automatically trades cryptocurrency prediction markets on Polymarket. You connect your crypto wallet, pick a coin (Bitcoin, Ethereum, Solana, or XRP) and a time window (5 minutes to daily), choose a trading strategy, and launch it. The bot then watches live prices every second, buys 'UP' or 'DOWN' tokens when your conditions are met, sells them when prices shift, and shows your portfolio value changing in real-time. It uses real money on the Polygon blockchain - no simulation, no paper trading.

How It Works

1
🔍 Discover the trading bot online

You find an open-source tool that watches crypto price predictions and automatically trades for you while you sleep.

2
💰 Connect your crypto wallet

You link a wallet that holds some digital dollars (USDC) on the Polygon network so the bot can trade with real money.

3
⚙️ Choose your trading style

You pick a strategy - either 'trade_1' to only sell positions you already have, or 'trade_2' to both buy new positions and sell them automatically.

4
🎯 Select which crypto to watch

You choose Bitcoin, Ethereum, Solana, or XRP and how often you want new markets (every 5 minutes, 15 minutes, hourly, or daily).

5
🚀 Launch the bot with one command

You start the program and it immediately connects to Polymarket, finds the current market, and begins watching price movements every second.

6
👀 Watch it trade automatically

The bot checks prices, decides when to buy or sell based on your settings, places real orders, and reports everything back to your screen in plain English.

📊 See your results in real-time

Your portfolio updates live as the bot makes trades, with colorful indicators showing whether prices are trending up or down and whether you're holding winning positions.

AI-Generated Review

What is arbitrage-trading-bot?

This is a TypeScript trading bot for Polymarket's crypto prediction markets. It automates buying and selling UP/DOWN tokens on Polymarket's CLOB, targeting short-horizon markets like "Bitcoin Up or Down in 5 minutes." The bot polls live order book prices every second, executes configurable entry and exit strategies, and places real on-chain orders using your actual USDC balance on Polygon. You configure strategy and market selection through a simple TOML file, then run it with a single npm command.

Why is it gaining traction?

Developers are drawn to this because it actually trades with real money rather than simulating. The code is clean TypeScript built on the official Polymarket client library, and it handles the messy parts: API authentication, signature type detection, retry logic, and balance polling. Two built-in strategies let you choose between pure exit management or a more aggressive entry/exit pattern with optional emergency position flips. The README is thorough and includes a disclaimer, which suggests the author understands the regulatory sensitivity of automated prediction market trading.

Who should use this?

This is for developers who already understand Polymarket's mechanics and want to run live trading strategies without building the plumbing from scratch. Not suitable for beginners--you need to understand how Polymarket proxy wallets work, manage USDC on Polygon, and interpret prediction market pricing. If you want to experiment with short-duration BTC/ETH/SOL/XRP markets and have capital you're willing to lose, this gives you a working starting point.

Verdict

At 82 stars with a credibility score of 0.699%, this is a small, early-stage project with limited community validation. The code is well-structured and documented, but there's no visible test coverage and the repository has only one contributor. Start with the minimum viable trade size and verify the strategy logic matches your expectations before scaling. Useful as a learning tool or foundation to fork, but not production-ready without significant hardening.
