Overview

Privacy-preserving identity verification using zero-knowledge proofs.

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.
