Introduction

Introduction to Veros developer tools and APIs

Veros provides developers with two powerful ways to verify users as unique humans — without compromising security or privacy. Our platform uses palm biometrics as a secure, universal identifier and offers two integration modes:

• Anonymous Mode (ZK Proofs): Users remain fully private. Your app receives a zero-knowledge proof, not personal data, to confirm uniqueness or eligibility.

• Pseudonymous Mode (OAuth-Style): For apps needing persistent user records, Veros issues a secure, app-scoped external_user_id, so you can link sessions without ever handling biometric data.

Key Components

• Veros Web Widget: A vanilla js component for web apps that displays a QR code for users to scan with their Veros app.

• Veros Mobile App: Handles palm scans, proof generation, and secure user verification.

• Veros Verifier: Cloud services for verifying ZK proofs when choosing Anonymous Mode integration.

Use Cases

• Passwordless login with persistent, privacy-safe IDs

• Sybil resistance and unique-human verification for dApps

• Age or eligibility verification without sharing sensitive data

• Multi-app loyalty or rewards systems with scoped identifiers
