How to Mint an ERC-20 Token on Base with the Interchain Token Service in 5 Steps - Moralis Web3

This step-by-step information will train you methods 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: Stipulations

You’ll need:

Step 2: Arrange a brand new challenge and required ABIs

On this step, you will want to create a brand new challenge 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 challenge:

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 challenge ABIs

Subsequent, arrange the ABI for the Interchain Token Manufacturing facility as will probably be wanted throughout deployment. Create a brand new file known as interchainTokenFactoryABI.json and add the Interchain Token Manufacturing facility ABI.

Create an .env file

To be sure to’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 challenge 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

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;

/** @kind import(‘hardhat/config’).HardhatUserConfig */
module.exports = {

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 challenge. 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’ll be able to mint a multichain ERC-20 token. For this tutorial, you’ll create a token utilizing the next data:

Identify: My New Token

Image: MNT

Decimals: 18

Create a brand new file named script.js. Import the mandatory dependencies:

Ethers.js

Moralis

The contract ABI

The InterchainTokenFactory contract deal with

Your token data

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
strive {
// 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.deal with
);

console.log(
`
Transaction Hash: ${deployTxData.hash},
salt: ${salt},
`
);
} catch (e) {
console.error(e);
}

Add a most important() perform

Add a most important() perform for executing script.js. It can deal with any errors that will come up:

//…

async perform most important() {
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;
}
}

most 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

You must 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: Test 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() {
strive {
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”, // Person deal with
});

console.log(response.uncooked);
} catch (e) {
console.error(e);
}
}

Replace most important() to get the token steadiness

Replace most important() to execute getBalance() :

//…

async perform most important() {
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

You must see one thing just like the next in your console:

Getting steadiness…
[
{
token_address: ‘0x274e53a526fa2543ce19f9c0334286b4724aa5e0’,
symbol: ‘MNT’,

logo: null,
thumbnail: null,
decimals: 18,

total_supply: ‘1000000000000000000000’,

}
]

Abstract
