Request

Your dApp creates a proof request via the ZKProofport SDK with specific verification requirements.

2

Prove

User generates a zero-knowledge proof on their mobile device using private credentials.

3

Verify

Your dApp verifies the cryptographic proof onchain or off-chain without accessing personal data.

JavaScript

import { ProofportSDK } from '@zkproofport-app/sdk';

// Initialize SDK
const sdk = ProofportSDK.create();

// Set a wallet signer for challenge-signature auth
sdk.setSigner(yourWalletSigner);

// Create a proof request via relay
const relay = await sdk.createRelayRequest('coinbase_attestation', {
  scope: 'myapp.com'
});

// Generate QR code for desktop users
const qrDataUrl = await sdk.generateQRCode(relay.deepLink);

// Wait over WebSocket. The relay always answers: completed,
// error, cancelled or expired (about 5 minutes after the request).
const result = await sdk.waitForProof(relay.requestId);
switch (result.status) {
  case 'completed':
    return verifyProof(result); // verify before trusting it
  case 'error':
  case 'failed': // older app versions
    return showError(result.error, result.errorCode);
  case 'cancelled': // declined in the app
    return offerRetry();
  case 'expired': // the app never answered
    return offerRetry();
  default:
