What is zKYC?

zKYC lets users verify their identity once and reuse a cryptographic proof instead of sharing raw documents across services.

Why it matters

Traditional KYC flows are repetitive, slow, and expose sensitive documents to every service. zKYC flips the model — verify once, then share minimal proofs.

Key benefits

  • •Privacy-first: personal data stays protected.
  • •Reusable proofs: one verification, many uses.
  • •Faster onboarding: fewer steps for users.

How it works

  1. 1.The user completes verification in zKYC once.
  2. 2.zKYC issues a small cryptographic proof.
  3. 3.Partner services validate the proof without seeing original documents.

For developers

Integrate once with the SDK and accept proofs — no need to process raw identity files in your app.

For product teams

Reduce drop-offs by removing repeated KYC steps and offer a privacy-first flow that builds trust.
