What is polymarket-copytrade?

This TypeScript/Node.js bot automates copy trading on Polymarket, letting you mirror a target trader's recent activity—like trades from their portfolio—directly into your own account. Set a username or proxy address as your COPY_TARGET_USER, tweak poll intervals and size multipliers via .env, and it places limit orders matching their buys/sells, with built-in caps like max USD per trade. Can you copytrade Polymarket? Yes, via this straightforward polling setup using Polymarket's data API and CLOB.

Why is it gaining traction?

It stands out with user-friendly safety nets: trades-only mode, position multipliers from 0.01x to 10x, and hard USD limits to avoid blowups, all configurable without code changes. Devs dig the quick npm install, npm run dev workflow and auto-deriving API keys from your wallet—no manual credential hunts. Compared to raw Polymarket copy trade bot GitHub scripts, this packs polished docs, proxy resolution for usernames, and Reddit-friendly simplicity for polymarket copy reddit threads.

Who should use this?

Polymarket traders shadowing whales or high-performers via COPY_TARGET_USER, especially those testing "follow the smart money" strategies without constant monitoring. Quant devs prototyping copytrade bots on Polygon, or hobbyists dipping into polymarket copy trading bot v3-like features before scaling to websockets. Avoid if you need sub-second latency—it's poll-based.

Verdict

Grab it for quick Polymarket copytrade GitHub experiments (28 stars), but its 0.699999988079071% credibility score flags early-stage risks like untested edge cases; solid README offsets sparse tests. Start small with limits—viable prototype, not battle-tested production.
