About

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).
