Audit trail

Permanent, verifiable records

Every action returns a unique reference ID. Query it any time for court-admissible proof.

01

Action returns ID

Every identify, sign, or message action returns a unique reference ID with a cryptographic proof.

02

Store ID safely

Save the reference ID in your system. It links to an immutable record of the action.

03

Query for verification

Query the reference ID any time to retrieve court-admissible proof of the original action.

Stack consolidation

What UIP replaces

01 / Identify
vs.
Auth0 · Okta · email + 2FA
  • Government-verified identity, not "the email is correct"
  • $0.01 per verification — no per-MAU seat fees
  • Reusable across every UIP-accepting business
02 / Sign
vs.
DocuSign · Adobe Sign · HelloSign
  • $0.03 per signature — versus $25–$300 per seat per month
  • Biometric signer identity baked into the proof, not "the email opened the link"
  • US ESIGN Act, UETA, and eIDAS AdES from the first signature, no premium tier required
03 / Message
vs.
Custom build · transactional email
  • End-to-end encrypted, addressed by verified identity — no spoofable email headers
  • $0.03 per message, $0.10 with attachments — priority flag bumps the in-app notification
  • Every send produces the same audit trail your signatures do

One vendor. One integration. Three primitives that share a verified identity, a unified audit trail, and per-action pricing — instead of three separate vendors with three sets of seat fees.

Legal validity

Where UIP signatures hold up

What UIP is

Signatures are legally binding under the US ESIGN Act and UETA, and meet eIDAS Advanced Electronic Signature (AdES) requirements across the EU.

Recognised in: United States, United Kingdom, European Union, Australia, Canada, Singapore, and more.

What UIP isn't

QES (Qualified Electronic Signature) is not currently supported. QES requires a qualified trust service provider designation under eIDAS.

If your use case specifically requires QES — typically certain regulated EU public-sector workflows — consult your legal team.
