Anon Aadhaar React Native

A React Native library that allows mobile applications to generate and verify zero knowledge proofs from the Aadhaar QR code.

Features

• Scan Aadhaar secure QR codes and verify the UIDAI signature
• Generate Groth16 proofs for the selected identity fields
• Provide a context provider for easy integration in React Native apps
• Includes a modal component to guide the user through the proof generation flow

Installation

# Yarn
yarn add @anon-aadhaar/react-native
# or npm
npm install @anon-aadhaar/react-native

The repository is a monorepo managed with Yarn workspaces. Run yarn in the root directory to install all dependencies including the example application.

Usage

1. Setup the prover – download the proving artifacts once when your app starts:

import { setupProver } from '@anon-aadhaar/react-native';

useEffect(() => {
  setupProver();
}, []);

2. Wrap your application with AnonAadhaarProvider so that child components can access the proof state:

import { AnonAadhaarProvider } from '@anon-aadhaar/react-native';

export default function App() {
  return (
    <AnonAadhaarProvider>
      {/* your navigation / screens */}
    </AnonAadhaarProvider>
  );
}

3. Trigger the proof creation using the AnonAadhaarProve component. It opens a modal that guides the user to scan the QR code and generates the proof.

import { AnonAadhaarProve } from '@anon-aadhaar/react-native';

<AnonAadhaarProve buttonMessage="Create Proof" nullifierSeed={1234} />;

Check the example/ folder for a complete Expo application demonstrating these steps.
