A private identity and signed-action service for applications, available as a developer sandbox built around pairwise account identifiers, OpenID Connect, WebAuthn, and post-quantum device-wallet proofs.
Veyns gives each application a separate account identifier. Applications do not receive wallet keys, device identifiers, biometric data, or a general user profile.
The same account can issue a fresh signed approval for an exact action, giving payments, sensitive account changes, and automated workflows an explicit authorization step.
Veyns provides standards-based sign-in while limiting the identity information shared with each connected application.
An application can request a separate user ceremony for a specific payment, account change, or automated action.
The current ceremony combines a post-quantum device-wallet proof with WebAuthn user verification.
The sandbox publishes the endpoints and tools needed to register an application and test the complete protocol surface.
The public environment is intended for developer evaluation and is not presented as a production identity service.
Production use requires a separately reviewed deployment profile, replicated storage, operating commitments, and security validation for the target application and assurance level.
ATL can scope this area as a focused component, an integration, or part of a complete engineering program.
