Overview
Prove your Polymarket account ownership with zero-knowledge proofs
Polymarket User Verifier lets you cryptographically prove ownership of your Polymarket account without revealing your login credentials. When a supported website requests verification, the extension generates a zero-knowledge proof attesting to your Polymarket user ID and proxy wallet address. The proof is generated entirely in your browser using WebAssembly — your authentication details never leave your device. How it works: 1. A supported website requests verification 2. You log into Polymarket as usual 3. The extension captures the relevant API response 4. A zero-knowledge proof is generated locally in your browser 5. The proof is sent to the requesting website Privacy: - No credentials are stored or shared - No browsing history is tracked - No analytics or telemetry - Proof generation happens locally Built with Reclaim Protocol (reclaimprotocol.org).
