Install

npm i zkproofaggregator-sdk

Create instance

1. Create zkpproofAggregator

create without deployed zkaFactory contract

import { ZkProofAggregator } from 'zkproofaggregator-sdk';

const zkpproofAggregator = new ZkProofAggregator(signer);

create with zkaFactory contract

import { ZkProofAggregator } from 'zkproofaggregator-sdk';

const zkpproofAggregator = new ZkProofAggregator(signer, zkaFactoryAddress);

reconnect signer

zkpproofAggregator.connect(newSigner);
spv.connect(newSigner);

2. Create SPV

create without deployed spv contract

import { SPV } from 'zkproofaggregator-sdk';

const spv = new SPV(signer);

create with spv contract

import { SPV } from 'zkproofaggregator-sdk';

const spv = new SPV(signer, spvAddress);

Deploy contracts

in development environment, you can deploy contracts by using the following methods.

const zkpproofAggregator = new ZkProofAggregator(signer);
await zkpproofAggregator.deploy();

const spv = new SPV(signer);
await spv.deploy();

you can check all detail in config

const zkaSatate = zkpproofAggregator.getConfig();
const spvState = spv.getConfig();

after call deploy methods, contracts address has been add to instance.config()

Verify zkproof in L2

1. create custom zkproof verifier

const zkpproofAggregator = new ZkProofAggregator(signer, zkaFactoryAddress);
const zkpVerifierName = "PLONK2";
const url = "http://localhost:3000";
const deployer = await zkpproofAggregator.getConfig().signer.getAddress();
const { tx, computeZKAVerifierAddress } =
  await zkpproofAggregator.deployZKAVerifier(
    zkpVerifierName,
    url,
    deployer,
    await plonk2MockVerifier.getAddress()
  );
await tx.wait();

2. fetch zkproof verifier

const zkpVerifierAddress = await zkpproofAggregator.fetchVerifiersMeta();

3. verify zkproof

const tx = await zkpproofAggregator.zkpVerify(currentVerifier, proof);
await tx.wait();

4. check proof verify status

const proofStatus = await zkpproofAggregator.checkProofVerifyStatus(
  currentVerifier,
  proofMock
);

verification in L1

const spv = new SPV(signer, spvAddress);
const tx = await spv.verify(proofMock);
await tx.wait();
