Universal Identity
Protocol
Biometric-first, self-sovereign identity and signature protocol — enabling users to authenticate and sign any digital action across devices, apps, or borders through modular API endpoints.
Biometric-First
Authenticate with your fingerprint or face. No passwords, no usernames, no security questions.
Universal
Works across any device, app, or country. One identity for everything, everywhere.
Self-Sovereign
Your identity belongs to you. Private keys stay on your device, no central authority.
