AI Summary

An open-source automation tool that places real trades on Polymarket's prediction markets, watching crypto price movements and executing buy/sell orders for UP or DOWN positions based on configurable time and price triggers.

How It Works

1
🔍 Discover prediction market trading

You hear about a way to make money by predicting whether Bitcoin or other crypto will go up or down in the next few minutes to 24 hours.

2
💻 Find the open-source bot

You discover a free tool online that automates these trades for you, so you don't have to watch prices all day.

3
🔗 Connect your crypto wallet

You link your digital wallet that holds USDC (a stable digital dollar) so the bot can use your funds to place trades.

4
⚙️ Choose your trading strategy

You pick how aggressive or conservative you want the bot to be - whether it should wait for perfect moments or act more quickly.

5
Watch the bot work automatically
📈
Strategy 1: Exit only

If you already own a prediction, the bot sells when the time is running out or prices move significantly

📊
Strategy 2: Entry and exit

The bot can both buy new predictions AND sell them, with an optional emergency swap to the opposite side

6
⏱️ Wait for the market to resolve

Once the time window ends, the market resolves based on whether the crypto went up or down, and your prediction either wins or loses.

💰 Collect your winnings or learn

If your prediction was correct, you receive USDC directly to your wallet. If not, you've lost the amount you wagered - just like any bet.

AI-Generated Review

What is polymarket-arbitrage-trading-bot?

A TypeScript bot that automates trading on Polymarket's prediction markets. It watches UP/DOWN contracts for crypto assets like BTC and ETH, polls the order book every second, and executes configurable strategies using real on-chain balances on Polygon. You configure strategy via TOML, point it at a wallet with USDC, and it loops through market windows placing FAK orders through the CLOB.

Why is it gaining traction?

The hook is "live trading with real money, not backtesting." Most trading bot repos are simulations. This one reads actual balances and submits on-chain orders immediately. The two built-in strategies handle entry, exit, and optional emergency swaps, so you can tune behavior without touching code. It supports proxy wallets, Gnosis Safes, and EOA signers with automatic fallback.

Who should use this?

Developers who want to experiment with Polymarket CLOB automation and have Polygon USDC to risk. Not for production trading unless you audit the retry logic, order validation, and balance handling thoroughly first. The 5-15 minute market windows suit short-horizon plays, not long-term positions.

Verdict

The 0.7% credibility score signals a young, unproven project with 79 stars and minimal community vetting. The documentation is solid and the code is readable, but there's no test suite visible and error handling relies heavily on retry loops rather than circuit breakers. Start with paper money and tiny trade sizes. This is a legitimate starting point for Polymarket automation, not a finished product you should trust with significant capital.
