zksync-storage

Typescript library to generate and verify zkSync storage proofs

Install

yarn

Usage

Verify operation is a very gas-exhaustive function (around 60M gas) and not every provider allows us to run it, code is tested to be working on Infura providers

import { SepoliaStorageProofProvider } from '@getclave/zksync-storage-proofs';

async function main() {
    const batchNumber = process.argv[2] ? parseInt(process.argv[2]) : undefined;

    const proof = await SepoliaStorageProofProvider.getProof(
        '0x0000000000000000000000000000000000008003',
        '0x8b65c0cf1012ea9f393197eb24619fd814379b298b238285649e14f936a5eb12',
        batchNumber,
    );
    console.log('Storage Proof', proof);

    const verified = await SepoliaStorageProofProvider.verifyOnChain(proof);
    console.log('Verified:', verified);
}

main();
