AI-Generated Review

What is polymarket-arbitrage-trade-bot?

This TypeScript bot automates a dump-and-hedge strategy for Polymarket arbitrage betting on 15-minute Up/Down markets like BTC, ETH, SOL, and XRP. It scans orderbooks via Polymarket's Gamma API and CLOB, detects sharp price dumps in the first few minutes of each period, buys the cheap side, and hedges the opposite when the combined cost dips below your target—locking in profit at settlement. Run it in simulation mode with `npm start` or go live with `npm run prod` after setting a Polygon wallet private key in `.env`.

Why is it gaining traction?

Unlike manual Polymarket arbitrage tools, this bot handles market discovery, period rollovers, stop-loss hedging, and token redemption automatically, with full P&L tracking in a TOML log. Developers dig the dry-run safety, proxy wallet support for GnosisSafe, and tweakable params like dump thresholds and share sizes—no real trades until you flip `PRODUCTION=true`. It's a ready-to-fork Polymarket arbitrage bot on GitHub that cuts out the polling and order math drudgery.

Who should use this?

Crypto traders building Polymarket arbitrage strategies around sports betting or price binaries, especially those with USDC on Polygon tired of babysitting 15m markets. Node.js scripters automating CLOB orders via API keys or signers, or quant devs testing dump-hedge tactics before scaling to multiple assets.

Verdict

Grab it if you're into Polymarket arbitrage scanning—solid docs and sim mode make it dev-friendly despite 85 stars and a 0.699999988079071% credibility score signaling early maturity. Test thoroughly in sim; lacks backtesting but delivers on core arbitrage execution out of the box.
