Six products around one idea: prove a fact without handing over everything else. Issuers put credentials in the wallet. Verifiers ask for a narrow slice. Each organisation only learns what its job requires.

- Wallet stores it on the phoneYou approve every share. Nothing is posted to a cloud profile.
- Venues, campus, city, and work ask narrowlyAge, diploma fields, name and city, or a badge — not a photocopy of your life.
