This page provides basic information on how to access the zkLoom Sepolia Testnet. If you want more details, see our guide for deploying to the zkLoom Testnet.

The zkLoom Sepolia Testnet is currently in a highly experimental phase, use it only for development and testing. The testnet state may be wiped on occassion as we fine tune the configuration and deploy new core features.

Hardhat Configuration

Here's an example of a Hardhat config that can be used to deploy Solidity contracts to the zkLoom Sepolia Testnet:

import { HardhatUserConfig } from "hardhat/config";
import "@matterlabs/hardhat-zksync-deploy";
import "@matterlabs/hardhat-zksync-solc";

const config: HardhatUserConfig = {
  defaultNetwork: "zkLoomSepolia",
  networks: {
    hardhat: {
      zksync: false,
    },
    zkLoomSepolia: {
      url: "http://zkloom-sepolia.dappchains.com:2052",
      zksync: true,
      ethNetwork: "https://sepolia.infura.io/v3/<API-KEY>"
    },
  },
  solidity: {
    version: "0.8.17",
  }
};

export default config;

Note that you'll need to replace <API-KEY> in the snippet above with your own Infura API key, you can obtain one when you sign up for a free account at https://app.infura.io/

You can find the full example in the 01-testnet-deploy project on Github.
