Polymarket Copy Trading Bot - Automate Top Wallets on Polygon

How It Works

Watch wallets. Copy trades. Collect.

Every second, the bot polls the wallets you're tracking. The instant they trade, you trade - proportionally sized to your deposit.

⚡

Sub-3-second execution

Polls target wallets every second via Polymarket's order book API. You fire almost as fast as they do.

⚖️

Proportional sizing

A $50k wallet bets $10k → your $3k wallet bets $1,200. Math adjusts automatically on every trade.

🛡️

6 safety guardrails

Staleness filters, price-drift gates, dedup checks, retry caps. No "oops" fills at broken prices.

🎯

Track up to 20 wallets

Diversify across multiple top traders. Comma-separate addresses in a single config line.

🔐

Your keys stay local

Signing happens on your machine. No telemetry, no key transmission, no hidden network calls. Ever.

📊

Full MongoDB audit log

Every detection, fill, and retry written to your database. Query it, analyze it, never lose it.

FAQ

Common questions.

Everything people ask before running the bot, answered honestly.

Do I need to know how to code?

No. If you can copy-paste commands and edit a text file in Notepad, you can run this bot. The setup is 5 steps and takes about 30 minutes end-to-end.

What's the minimum deposit to actually make money?

$3,000–$5,000 is the sweet spot. Below $500, many markets won't fill. Between $500–$2,000 you get real fills but tiny dollar gains. Above $20k requires advanced wallet selection.

Is the bot safe? Can it steal my money?

Your private key signs trades locally and never leaves your machine. No telemetry, no hidden network calls. The signing code is 40 lines - you can read it yourself in src/utils/createClobClient.ts before funding anything.

How realistic are the returns?

Expect 70–85% of your copied wallet's returns after slippage. If the trader you're copying returns 40% over 3 months, you'll likely see 28–34%. Past performance never guarantees future results.

Can I run this on a cheap server instead of my laptop?

Yes - any $5/month VPS (DigitalOcean, Hetzner, Vultr) runs it fine. Recommended once you've deposited over $1,000 so it keeps running when your laptop sleeps.

What if the wallet I'm copying starts losing?

Every wallet has losing streaks. That's why you diversify to 3–5 wallets and review logs weekly to rotate out underperformers.

Is Polymarket legal where I live?

Polymarket restricts some regions (including the US). Check your local laws. This software is provided for educational purposes - you're responsible for compliance.

How often do I need to check on it?

Every 2–3 days, for about 5 minutes. Make sure it's running, logs look clean, and the database is filling up.
