This step-by-step guide will teach you how to mint a multichain ERC-20 token on the Base network using Axelar’s Interchain Token Service (ITS) and use the Moralis Token API to easily retrieve token balances.
Step 1: Prerequisites
You will need:
Step 2: Set up a new project and required ABIs
In this step, you will need to create a new project and set up the required ABIs to interact with ITS and mint your ERC-20 token on the Base network.
Open your terminal and navigate to any directory of your choice. Run the following commands to create and initiate a project:
mkdir mint-token && cd mint-token
npm init -y
Install Hardhat and Moralis
Install Hardhat and Moralis with the following commands:
npm install –save-dev @nomiclabs/hardhat-ethers ethers moralis
Set up project ABIs
Next, set up the ABI for the Interchain Token Factory as it will be needed during deployment. Create a new file called interchainTokenFactoryABI.json and add the Interchain Token Factory ABI.
Create an .env file
To make sure you’re not accidentally publishing your private key, create an .env file to store it in:
touch .env
Add your private key to .env
Export your private key and add it to the .env file you just created:
PRIVATE_KEY= // Add your account private key here
💡 If you will push this project on GitHub, create a .gitignore file and include .env.
Step 3: Set up the remote procedure call (RPC)
Next, you’ll need to set up the RPC. Navigate to the directory where you installed Hardhat and run the following command:
npx hardhat init
Select “Create an empty hardhat.config.js” with your keyboard and hit enter.
Next, update hardhat.config.js with the following code snippet:
/** @type import(‘hardhat/config’).HardhatUserConfig */
require(“@nomiclabs/hardhat-ethers”);
require(“dotenv”).config({ path: “.env” });
const PRIVATE_KEY = process.env.PRIVATE_KEY;
/** @type import(‘hardhat/config’).HardhatUserConfig */
module.exports = {
solidity: “0.8.19”,
networks: {
base: {
url: “<https://base-sepolia-rpc.publicnode.com>”,
chainId: 84532,
accounts: [PRIVATE_KEY],
},
},
};
Hardhat runs by locating the nearest hardhat.config.js from the current directory, typically found at the root of your project. Even an empty hardhat.config.js allows Hardhat to function, as your entire setup is housed in this file.
Step 4: Mint an ERC-20 token with ITS
Now that you’ve set up a Base Sepolia testnet RPC, you can mint a multichain ERC-20 token. For this tutorial, you will create a token using the following information:
Name: My New Token
Symbol: MNT
Decimals: 18
Create a new file named script.js. Import the necessary dependencies:
- Ethers.js
- Moralis
- The contract ABI
- The InterchainTokenFactory contract address
- Your token information
Create a mintToken() function
Create a mintToken() function for minting a new token on the Base Sepolia testnet:
Add a main() function
Add a main() function for executing script.js. It will handle any errors that may arise:
Run script.js to deploy your token to the Base Sepolia testnet
Run the script in your terminal to create and mint the token, specifying the Base Sepolia testnet:
Step 5: Check the minted token balance with the Moralis API
Now that you have successfully minted your new token, it’s time to retrieve the balance.
Add the Moralis API key to .env
Get your token balance
Add the following in the script.js file:
Update main() to get the token balance
Update main() to execute getBalance() :
Run the script in your terminal to retrieve your token:
Summary
The tutorial provides a step-by-step guide on minting a multichain ERC-20 token on the Base Sepolia network using Axelar’s Interchain Token Service (ITS). The process involves setting up prerequisites, creating a new project and ABIs, setting up a remote procedure call (RPC), minting the ERC-20 token with ITS, and checking the minted token balance with the Moralis API.
