Overview

Privacy-preserving identity verification using zero-knowledge proofs.

Looking for Self Enterprise? Self Pass is the open-source SDK where you render your own QR and run the verifier. On the managed Enterprise platform you do neither, see the Enterprise quickstart.

Overview

Self Pass enables developers to verify real-world identity attributes without exposing personal data. Users scan their passport, national ID, Aadhaar card, or KYC attestation with the Self app, which generates a zero-knowledge proof on-device. Applications can then verify specific attributes (age, nationality, sanctions status) without ever seeing the underlying document.

Supported Documents

• Passports — NFC-enabled passports from 60+ countries

• EU National ID Cards — Chip-enabled European identity cards

• Aadhaar — India's national identity system

• KYC Attestations — Third-party KYC provider attestations

Getting Started

Start with the Quickstart guide, or fork the boilerplate repo for a working example.
