Capabilities

Three primitives.
One identity.

Everything UIP does is one of identify, sign, or message — each metered, each anchored to the same verified credential.

01 / IDENTIFY

Passwordless authentication

Your users scan a QR code and confirm with a face or fingerprint. You receive a signed, government-verified identity response over a webhook.

Biometric + device attestation
Verified name, DOB, country, and document status
Sub-500 ms end-to-end response

$0.01 / verification

02 / SIGN

Legally binding signatures

Document signing anchored to a government-verified identity and a precise UTC timestamp. Every signature is eIDAS AdES, admissible in court.

eIDAS AdES — court-admissible
Anchored to verified identity keypair
Permanent, queryable audit reference

$0.03 / signature

03 / MESSAGE

Encrypted messaging

End-to-end encrypted messages addressed by verified identity — not phone number or email. Attachments and priority are part of the protocol.

Secure

Your biometric template is created and held inside the device’s secure enclave — it never leaves your phone. A keypair representing your verified identity is generated alongside it.

Secure Enclave · X25519

Use

Authenticate, sign, and message anywhere UIP is accepted. Every action returns a permanent reference ID, queryable at any time for a full audit trail.

Cross-platform · Auditable

Who it's for

kinds of user.
