AI-Generated Review

What is polymarket-arbitrage?

This TypeScript bot automates polymarket arbitrage betting on 15-minute up/down prediction markets for BTC, ETH, SOL, and XRP via Polymarket's Gamma API and CLOB. It spots sudden price dumps in one outcome token, buys in cheap, then hedges the opposite side when their prices sum below a target like 0.95 USDC—locking expected profits since one outcome pays $1. Run it in simulation mode or live with your private key, and it handles orders, stop-losses, market closure checks, and token redemptions.

Why is it gaining traction?

Unlike manual polymarket arbitrage tools or generic scanners, this bot focuses on a proven dump-hedge strategy with auto market discovery, real-time monitoring every second, and built-in profit tracking across cycles. Devs dig the .env config for thresholds like move detection (15% drop) and watch windows (2 minutes), plus proxy wallet support for safer trading—no need to hunt slugs or build from Polymarket GitHub API docs.

Who should use this?

Quant traders or crypto botsmiths grinding Polymarket arbitrage strategies on hourly rounds. Ideal for those scanning Reddit for polymarket arbitrage opportunities but wanting a set-it-and-forget-it scanner with hedging logic, or devs prototyping polymarket arbitrage calculators before scaling to Rust/Python clones.

Verdict

Grab it for simulation testing—solid for learning Polymarket CLOB and websocket flows—but skip live deploys until more stars (just 28) and that 0.699999988079071% credibility score climb. Thin docs mean tweaking configs yourself; fork and harden for production.
