This step-by-step information will educate you how one can 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: Stipulations
You’ll need:
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 facility as it is going to be wanted throughout deployment. Create a brand new file referred to as interchainTokenFactoryABI.json and add the Interchain Token Manufacturing facility ABI.
Create an .env file
To ensure you’re not unintentionally publishing your non-public key, create an .env file to retailer it in:
contact .env
Add your non-public key to .env
Export your non-public key and add it to the .env file you simply created:
PRIVATE_KEY= // Add your account non-public key right here
💡 If you’ll push this mission on GitHub, create a .gitignore file and embrace .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 along with your keyboard and hit enter:
888 888 888 888 888

Create a JavaScript mission
Create a TypeScript mission
Create a TypeScript mission (with Viem)
❯ Create an empty hardhat.config.js
Stop
Subsequent, replace hardhat.config.js with the next code snippet:
/** @sort import(‘hardhat/config’).HardhatUserConfig */
require(“@nomicfoundation/hardhat-toolbox”);
require(“dotenv”).config({ path: “.env” });
const PRIVATE_KEY = course of.env.PRIVATE_KEY;
/** @sort 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 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 total setup is housed on this file.
Step 4: Mint an ERC-20 token with ITS
Now that you just’ve arrange a Base Sepolia testnet RPC, you’ll be able to mint a multichain ERC-20 token. For this tutorial, you’ll create a token utilizing the next info:
Identify: My New Token
Image: MNT
Decimals: 18
Create a brand new file named script.js. Import the required dependencies:
Ethers.js
Moralis
The contract ABI
The InterchainTokenFactory contract tackle
Your token info
const 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 identify = “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,
identify,
image,
decimals,
initialSupply,
signer.tackle
);
console.log(
`
Transaction Hash: ${deployTxData.hash},
salt: ${salt},
`
);
} catch (e) {
console.error(e);
}
Add a important() perform
Add a important() perform for executing script.js. It is going to deal with any errors that will come up:
//…
async perform important() {
const functionName = course of.env.FUNCTION_NAME;
swap (functionName) {
case “mintToken”:
await mintToken();
break;
default:
console.error(`Unknown perform: ${functionName}`);
course of.exitCode = 1;
return;
}
}
important().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 just 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 got 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
tackle: “0x510e5EA32386B7C48C4DEEAC80e86859b5e2416C”, // Person tackle
});
console.log(response.uncooked);
} catch (e) {
console.error(e);
}
}
Replace important() to get the token steadiness
Replace important() to execute getBalance() :
//…
async perform important() {
const functionName = course of.env.FUNCTION_NAME;
swap (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 just like the next in your console:
Getting steadiness…

Abstract
The tutorial supplies 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 includes establishing conditions, creating a brand new mission and ABIs, establishing a distant process name (RPC), minting the ERC-20 token with ITS, and checking the minted token steadiness with the Moralis API.
