This step-by-step information will educate you find out how to mint a multichain ERC-20 token on the Base community utilizing Axelar’s Interchain Token Service (ITS) and use the Moralis Token API to simply retrieve token balances.
Step 1: Conditions
You will want:
Step 2: Arrange a brand new mission and required ABIs
On this step, you’ll need to create a brand new mission and arrange the required ABIs to work together with ITS and mint your ERC-20 token on the Base community.
Open your terminal and navigate to any listing of your alternative. Run the next instructions to create and provoke a mission:
mkdir mint-token && cd mint-token
npm init -y
Set up Hardhat and Moralis
Set up Hardhat and Moralis with the next instructions:
npm set up –save-dev [email protected] [email protected]
[email protected] @nomicfoundation/[email protected] moralis
Arrange mission ABIs
Subsequent, arrange the ABI for the Interchain Token Manufacturing unit as will probably be wanted throughout deployment. Create a brand new file known as interchainTokenFactoryABI.json and add the Interchain Token Manufacturing unit ABI.
Create an .env file
To be sure you’re not by accident publishing your personal key, create an .env file to retailer it in:
contact .env
Add your personal key to .env
Export your personal key and add it to the .env file you simply created:
PRIVATE_KEY= // Add your account personal key right here
💡 If you’ll push this mission on GitHub, create a .gitignore file and embody .env.
Step 3: Arrange the distant process name (RPC)
Subsequent, you’ll must arrange the RPC. Navigate to the listing the place you put in Hardhat and run the next command:
npx hardhat init
Choose Create an empty hardhat.config.js together with your keyboard and hit enter:

Subsequent, replace hardhat.config.js with the next code snippet:
/** @kind import(‘hardhat/config’).HardhatUserConfig */
require(“@nomicfoundation/hardhat-toolbox”);
require(“dotenv”).config({ path: “.env” });
const PRIVATE_KEY = course of.env.PRIVATE_KEY;

base: {
url: “<https://base-sepolia-rpc.publicnode.com>”,
chainId: 84532,
accounts: [PRIVATE_KEY],
},
},
};
Hardhat runs by finding the closest hardhat.config.js from the present listing, sometimes discovered on the root of your mission. Even an empty hardhat.config.js permits Hardhat to perform, as your whole setup is housed on this file.
Step 4: Mint an ERC-20 token with ITS
Now that you simply’ve arrange a Base Sepolia testnet RPC, you possibly can mint a multichain ERC-20 token. For this tutorial, you’ll create a token utilizing the next info:
Identify: My New TokenSymbol: MNTDecimals: 18
Create a brand new file named script.js. Import the mandatory dependencies:
Ethers.jsMoralisThe contract ABIThe InterchainTokenFactory contract addressYour token informationconst hre = require(“hardhat”);
const crypto = require(“crypto”);
const Moralis = require(“moralis”).default;
const ethers = hre.ethers;
const interchainTokenFactoryContractABI = require(“./interchainTokenFactoryABI”);
const interchainTokenFactoryContractAddress =
“0x83a93500d23Fbc3e82B410aD07A6a9F7A0670D66”;
// Create a brand new token
const title = “My New Tokenn”;
const image = “MNT”;
const decimals = 18;
// Intial token to be minted
const initialSupply = ethers.utils.parseEther(“1000”);
Create a mintToken() perform
Create a mintToken() perform for minting a brand new token on the Base Sepolia testnet:
//…
// Mint a brand new ERC-20 multichain token to the Base Sepolia testnet
attempt {
// Generate random salt
const salt = “0x” + crypto.randomBytes(32).toString(“hex”);
// Get a signer to signal the transaction
const [signer] = await ethers.getSigners();
// Create contract cases
const interchainTokenFactoryContract = await new ethers.Contract(
interchainTokenFactoryContractAddress,
interchainTokenFactoryContractABI,
signer
);
// Deploy the token
const deployTxData =
await interchainTokenFactoryContract.deployInterchainToken(
salt,
title,
image,
decimals,
initialSupply,
signer.deal with
);
console.log(
`
Transaction Hash: ${deployTxData.hash},
salt: ${salt},
`
);
} catch (e) {
console.error(e);
}
Add a primary() perform
Add a primary() perform for executing script.js. It is going to deal with any errors which will come up:
//…
async perform primary() {
const functionName = course of.env.FUNCTION_NAME;
change (functionName) {
case “mintToken”:
await mintToken();
break;
default:
console.error(`Unknown perform: ${functionName}`);
course of.exitCode = 1;
return;
}
}
primary().catch((error) => {
console.error(error);
course of.exitCode = 1;
});
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:
FUNCTION_NAME=mintToken npx hardhat run script.js –network base
It’s best to see one thing much like the next in your console:
Transaction Hash: 0x7695f2dd6e29240fc792d37fd6b86f402f2b5338e088e0ad4a448685e0ad565b,
salt: 0xef36cf55326c3fb9fb47c6d3828b8a4ea12fdfab31aae4bc3634bf7bbe04eb49,
Transaction: https://sepolia.basescan.org/tx/0x7695f2dd6e29240fc792d37fd6b86f402f2b5338e088e0ad4a448685e0ad565b Token: https://sepolia.basescan.org/token/0x274e53a526fa2543ce19f9c0334286b4724aa5e0
Step 5: Examine the minted token steadiness with the Moralis API
Now that you’ve efficiently minted your new token, it’s time to retrieve the steadiness.
Add the Moralis API key to .env
MORALIS_API_KEY= // Add you Moralis API key right here
Get your token steadiness
Add the next within the script.js file:
//…
const MORALIS_API_KEY = course of.env.MORALIS_API_KEY;
// Get consumer steadiness with the Moralis API
async perform getBalance() {
attempt {
console.log(“Getting steadiness…”);
await Moralis.begin({
apiKey: MORALIS_API_KEY,
});
const response = await Moralis.EvmApi.token.getWalletTokenBalances({
chain: “84532”, // Base Sepolia
deal with: “0x510e5EA32386B7C48C4DEEAC80e86859b5e2416C”, // Consumer deal with
});
console.log(response.uncooked);
} catch (e) {
console.error(e);
}
}
Replace primary() to get the token steadiness
Replace primary() to execute getBalance() :
//…
async perform primary() {
const functionName = course of.env.FUNCTION_NAME;
change (functionName) {
//…
case “getBalance”:
await getBalance();
break;
default:
//…
}
}
Run the script in your terminal to retrieve your token:
FUNCTION_NAME=getBalance node script.js
It’s best to see one thing much like the next in your console:
Getting steadiness…

Abstract
The tutorial offers a step-by-step information on minting a multichain ERC-20 token on the Base Sepolia community utilizing Axelar’s Interchain Token Service (ITS). The method entails organising stipulations, creating a brand new mission and ABIs, organising a distant process name (RPC), minting the ERC-20 token with ITS, and checking the minted token steadiness with the Moralis API.
