ZetaChain Blockchain Networks Registry

This registry is a list of blockchain networks connected to ZetaChain.

Building a dapp on ZetaChain

If you're looking to build a dapp on ZetaChain, we recommend using the Hardhat template. This template has all the networks preconfigured, so you don't need to install this package manually.

Prerequisites

Before getting started, ensure that you have Node.js and Yarn installed on your system.

Installation

To install this package in Hardhat project, add it as a development dependency:

yarn add --dev @zetachain/networks

Usage

In your hardhat.config.ts file, import the getHardhatConfigNetworks function from @zetachain/networks:

import { getHardhatConfigNetworks } from "@zetachain/networks";

const config: HardhatUserConfig = {
  networks: {
    ...getHardhatConfigNetworks(),
  },
};

In this configuration, the getHardhatConfigNetworks function returns all available networks from ZetaChain and spreads them into the networks object. This way, the Hardhat environment is configured to interact with all the networks connected to ZetaChain.

getHardhatConfigNetworks reads the private key from PRIVATE_KEY environment variable and defaults to an empty account array if the variable not set, and throws an error if the private key is invalid.

In a Browser Environment

@zetachain/networks is released as a CommonJS project to work out of the box with the current version of Hardhat. You can use it in a browser environment by using a bundler like Vite.

vite.config.ts:

import { defineConfig } from "vite";

export default defineConfig({
  optimizeDeps: {
    include: ["@zetachain/networks"],
  },
});

You can now use @zetachain/networks in your browser environment:

import { getHardhatConfigNetworks } from "@zetachain/networks";

Network List Validation

If you modify the list of networks, it's crucial that the updated list aligns with the predefined schema. For this, you can use the in-built validation command:

yarn validate

Running the Getters

Getters are designed to access and output the data of the network list. To execute the getters and print their output to the console, use the following command:

yarn output

This command will run the getter functions and display the resulting output in your terminal.
