Deploy paymaster

Deploy the paymaster account, which will receive the token deployed in the previous step and pay the fee in ETH for the account that sends the token. The token address on testnet that is deployed in previous step is 0xCd9BDa1d0FC539043D4C80103bdF4f9cb108931B

Deploy paymaster with CREATE opcode

import { Provider, types, Wallet, ContractFactory } from "zksync2-js";

const provider = Provider.getDefaultProvider(types.Network.Goerli);
const PRIVATE_KEY = process.env.PRIVATE_KEY;
const wallet = new Wallet(PRIVATE_KEY, provider);

const tokenAddress = "0xCd9BDa1d0FC539043D4C80103bdF4f9cb108931B";

async function main() {
  const conf = require("../../solidity/custom_paymaster/paymaster/build/Paymaster.json");
  const abi = conf.abi;
  const bytecode: string = conf.bytecode;

  const factory = new ContractFactory(abi, bytecode, wallet, "createAccount");
  const account = await factory.deploy(tokenAddress);
  console.log(`Account address: ${await account.getAddress()}`);
}

main()
  .then()
  .catch((error) => {
    console.log(`Error: ${error}`);
  });

Deploy paymaster with CREATE2 opcode

import { Provider, types, Wallet, ContractFactory } from "zksync2-js";
import { ethers } from "ethers";

const provider = Provider.getDefaultProvider(types.Network.Goerli);
const PRIVATE_KEY = process.env.PRIVATE_KEY;
const wallet = new Wallet(PRIVATE_KEY, provider);

const tokenAddress = "0xCd9BDa1d0FC539043D4C80103bdF4f9cb108931B";

async function main() {
  const conf = require("../../solidity/custom_paymaster/paymaster/build/Paymaster.json");
  const abi = conf.abi;
  const bytecode: string = conf.bytecode;

  const factory = new ContractFactory(abi, bytecode, wallet, "create2Account");
  const account = await factory.deploy(tokenAddress, {
    customData: { salt: ethers.hexlify(ethers.randomBytes(32)) },
  });
  console.log(`Account address: ${await account.getAddress()}`);
}

main()
  .then()
  .catch((error) => {
    console.log(`Error: ${error}`);
  });
