AI-Generated Review

What is polymarket-copy-trading-bot?

This Node.js bot automates trading on Polymarket's 5-minute BTC up/down prediction markets on Polygon, handling real USDC orders via the CLOB API and WebSocket feeds. In arbitrage mode, it posts limit ladders on both outcomes, snags mispricings when combined asks dip below 98 cents, merges matched pairs for profit, and redeems winnings post-resolution. Copy trading mode mirrors a target wallet's buys with sizing caps, slippage limits, and dry-run testing—npm start for arb, or a standalone script for pure copying.

Why is it gaining traction?

It packs session risk controls like hourly loss breakers and per-market spend caps, plus auto Polygon approvals and credential derivation, cutting setup friction versus raw Polymarket GitHub API wrappers. Performance screenshots prove edge in live BTC markets, and the dedicated copy trader polls public trade feeds at 250ms for low-latency mirroring—faster than manual Reddit-sourced bots in Python or Rust. Dry-run and structured logs make iteration painless.

Who should use this?

Polymarket power users chasing BTC arb edges without babysitting orders, copy traders tailing whale wallets from Telegram or Reddit threads, or DeFi scripters prototyping on the gamma API and clob endpoints. JS devs familiar with ethers.js will ramp up quickest for custom tweaks.

Verdict

Grab it if you're dipping into Polymarket trading bots—excellent README with .env checklists and troubleshooting beats most GitHub clones. At 93 stars and 0.800000011920929% credibility, it's promising but unproven; test small, review bot.log religiously before scaling.
