AI Summary

This is a copy trading bot for Polymarket that automatically mirrors another trader's activity on your own account. You pick a target trader, set safety limits like how much to scale their trades and a maximum per-trade cap, and the bot periodically checks their activity and places similar orders from your wallet. It uses official Polymarket interfaces to read trading data and place orders, and it includes clear warnings that copy trading means you can lose money when the leader loses too.

How It Works

1
💡 You hear about a trader you want to follow

You discover someone on Polymarket whose trading style impresses you, and you wish you could automatically do the same trades they make.

2
🔧 You set up your trading account

You connect your Polymarket account to the bot using your wallet address, and the bot gets ready to watch activity on your behalf.

3
👤 You choose who to copy

You enter the username or wallet address of the trader you want to follow, and the bot looks up their trading history.

4
⚙️ You set your safety limits

You decide how much to scale their trades (starting small) and set a maximum amount you're willing to risk on any single copied trade.

5
The bot starts watching and copying
📊
New trade detected

The bot finds a trade it hasn't copied yet and places a similar order for you

⏭️
No new activity

The bot checks but finds nothing new, so it waits for the next check

6
📈 You watch your portfolio grow

Over time, you see your account reflect the trades of the trader you chose to follow, scaled to your comfort level.

🎉 You're now copy trading successfully

Your bot is running on autopilot, following your chosen trader while you stay in control through the limits you set.

AI-Generated Review

What is polymarket-copy-trading-bot?

This is a TypeScript bot that automatically mirrors another trader's positions on Polymarket. You point it at a target wallet or username, set a size multiplier and max order cap, and it periodically checks what trades they made, then places scaled copies from your own account. It connects to Polymarket's CLOB and data APIs, handles the proxy wallet signature flow, and runs as a simple Node process you leave in a terminal.

Why is it gaining traction?

The setup is refreshingly straightforward: clone, configure a few environment variables, and run. The README is unusually honest about limitations, warning users to start small and never commit private keys. It handles the messy details of Polymarket's proxy architecture automatically, which is where most similar projects stumble. The polling approach is explicitly framed as copy-trading, not arbitrage, which sets realistic expectations.

Who should use this?

DeFi traders who want to follow a specific Polymarket whale without manually tracking activity. Developers building their own copy-trading infrastructure will find the source readable and the API integration patterns useful. Casual users looking for a set-and-forget solution should be comfortable with command-line tools and comfortable accepting that this is a hobbyist project with real financial risk.

Verdict

At 84 stars with minimal test coverage, this is an early-stage tool that rewards careful experimentation over production deployment. The 0.699999988079071% credibility score reflects a project in active development with a small audience. Start with a tiny multiplier, a dedicated wallet, and funds you can afford to lose. The code is clean enough to trust for learning, but not mature enough to trust with serious capital.
