examples

Quick start

Initialize Prover

import { zKtrace } from '@zktrace/sdk';

const prover = new zKtrace({
  network: 'mainnet-beta',
  programId: 'ZKtr4cE...',
  commitment: 'confirmed'
});

await prover.connect();

Generate Proof

const proof = await prover.generateProof({
  type: 'identity',
  data: walletPubkey,
  witnesses: attestations
});

// Proof size: 1.2KB
// Compression: 99.97%
console.log(proof.hash);

Verify On-Chain

const verification = await prover.verify({
  proof: proof.hash,
  publicInputs: [commitment],
  verifierKey: VERIFIER_KEY
});

// Verified: true
// Cost: 0.000012 SOL
