Automated dump-and-hedge arbitrage bot for Polymarket's 15-minute crypto Up/Down prediction markets. Written in TypeScript using the official @polymarket/clob-client. Watches BTC, ETH, SOL, and XRP markets for sharp price drops on one leg, then buys both legs when combined cost falls below a target threshold to lock in a structural edge before resolution.
