ProveOnce

ProveOnce lets you verify your age and identity privately — once — and carry that proof anywhere it's needed.

Instead of handing your ID to every app, bar, or website that asks, you verify once through a secure, one-time process. ProveOnce issues a tamper-evident digital credential that merchants and platforms can check without ever seeing your name, date of birth, or ID document.

Your wallet holds all your active tokens so you can see exactly who has verified you and revoke access at any time.

FEATURES
• One-time identity and age verification
• Privacy-first: merchants see yes/no, never your personal data
• Secure digital wallet with all your active tokens
• Instant revocation — remove any merchant's access in one tap
• Tamper-evident Ed25519-signed credentials
• Built on ProveOnce, a purpose-built identity verification platform

ProveOnce is designed for anyone who values privacy and wants to stop re-submitting their ID to every service that requires age or identity verification.
