Deposit ETH

This is an example of how to deposit ETH from Ethereum network (L1) to zkSync Era network (L2):

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

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

async function main() {
  console.log(`L2 balance before deposit: ${await wallet.getBalance()}`);
  console.log(`L1 balance before deposit: ${await wallet.getBalanceL1()}`);

  const tx = await wallet.deposit({
    token: utils.ETH_ADDRESS,
    to: await wallet.getAddress(),
    amount: 7_000_000_000,
    refundRecipient: await wallet.getAddress(),
  });
  const receipt = await tx.wait();
  console.log(`Tx: ${receipt.hash}`);

  console.log(`L2 balance after deposit: ${await wallet.getBalance()}`);
  console.log(`L1 balance after deposit: ${await wallet.getBalanceL1()}`);
}

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

Deposit tokens

This is an example of how to deposit tokens from Ethereum network (L1) to zkSync Era network (L2):

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

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

async function main() {
  // Crown token which can be mint for free
  const tokenL1 = "0xc8F8cE6491227a6a2Ab92e67a64011a4Eba1C6CF";
  const tokenL2 = await provider.l2TokenAddress(tokenL1);

  console.log(`L2 balance before deposit: ${await wallet.getBalance(tokenL2)}`);
  console.log(`L1 balance before deposit: ${await wallet.getBalanceL1(tokenL1)}`);

  const tx = await wallet.deposit({
    token: tokenL1,
    to: await wallet.getAddress(),
    amount: 5,
    approveERC20: true,
    refundRecipient: await wallet.getAddress(),
  });
  const receipt = await tx.wait();
  console.log(`Tx: ${receipt.hash}`);

  console.log(`L2 balance after deposit: ${await wallet.getBalance(tokenL2)}`);
  console.log(`L1 balance after deposit: ${await wallet.getBalanceL1(tokenL1)}`);
}

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