AI-Generated Review

What is polymarket-arbitrage?

This TypeScript bot automates Polymarket arbitrage betting via the platform's CLOB API and Gamma API, targeting 15-minute up/down markets on assets like BTC, ETH, SOL, and XRP. It scans for sudden price dumps in one outcome token, buys shares immediately, then hedges the opposite side when their prices sum below a configurable target (e.g., 0.95), locking in risk-free profit since winning tokens redeem at $1 USDC. Run it in simulation mode to test or live with your private key for real trades, including auto-redemption post-resolution.

Why is it gaining traction?

Unlike manual Polymarket arbitrage tools or generic scanners, this bot executes a precise dump-hedge strategy with stop-losses, price history checks, and multi-market monitoring, handling order placement and fills seamlessly. Developers dig the .env-driven config for quick tweaks like share size, thresholds, and intervals, plus profit tracking across cycles. It's a ready-to-fork Polymarket arbitrage bot on GitHub, bridging prediction markets and crypto price action for consistent edges.

Who should use this?

Quantitative traders or Polymarket power users hunting arbitrage strategies on short-term crypto directionals. Suited for those with Polygon wallets tired of babysitting order books, or devs prototyping Polymarket GitHub bots for CLOB trading and websocket-like polling. Ideal if you're scanning Reddit for Polymarket arbitrage tips and want an automated finder and executor.

Verdict

Grab it if you're experimenting with Polymarket arbitrage calculator logic—28 stars and 0.7% credibility score signal early days with thin docs and no tests, but the core strategy works in sim mode for low-risk validation. Fork and harden for production; skip if you need battle-tested maturity.
