Hardhat tasks for the ZetaChain template

Prerequisites

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

Getting Started

To get started, install the necessary dependencies by running the following command in your terminal:

yarn

Installing tasks

To install all the the tasks into a Hardhat template, add the following import statement to hardhat.config.js:

import "@zetachain/tasks";

You can also import specific tasks:

import "@zetachain/tasks/account";
import "@zetachain/tasks/balances";

Compiling Tasks

yarn build

Hardhat Tasks

This template includes two Hardhat tasks that can be used to generate a random wallet and request tokens from ZetaChain's faucet.

Generating a Random Wallet

To generate a random wallet, run the following command in your terminal:

npx hardhat account --save

This will generate a random wallet, print information about the wallet to the terminal, and save the private key to a .env file to make it accessible to Hardhat. If you don't want to save the wallet (for example, if you just need an address to send tokens to), you can run the command without the --save flag.

Querying for Token Balances

To query for token balances, run the following command in your terminal:

npx hardhat balances

This command will query token balances for the account address derived from the private key specified in the .env.

If you want to query for token balances for a different account, you can use the --address flag:

npx hardhat balances --address <address>

Requesting Tokens from the Faucet

To request tokens from ZetaChain's faucet using the account from the .env file, run the following command in your terminal:

npx hardhat faucet

To install a standalone faucet, run the following command in your terminal:

npm install -g @zetachain/faucet-cli

You can then use it with the following command:

zetafaucet -h

Verifying a Contract

You can verify a deployed contract with the following command:

npx hardhat verify:zeta --contract <address>

Select the contract to verify:

? Select a contract to verify: (Use arrow keys)
  @zetachain/zevm-protocol-contracts/contracts/interfaces/IZRC20.sol:IZRC20
  @zetachain/zevm-protocol-contracts/contracts/interfaces/zContract.sol:zContract
❯ contracts/Withdraw.sol:Withdraw

After the confirmation the contract will be verified.
