What is PolySniper?

PolySniper is a Chrome extension that scans Polymarket negRisk events for apparent arbitrage gaps and checks current CLOB order-book depth and spreads. Its narrow form factor is intended for research rather than executing trades. Pricing and wallet requirements remain unknown, the public user base is small, and any displayed opportunity can disappear before a user acts.
