Mint an ERC-20 Token on Base with the Interchain Token Service in 5 Steps – Moralis for Builders

[ad_1]

This step-by-step information will train you how you 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 venture and required ABIs

On this step, you’ll need to create a brand new venture 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 venture:

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 venture 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 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 venture on GitHub, create a .gitignore file and embrace .env.

Step 3: Arrange the distant process name (RPC)

Subsequent, you’ll have to 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:

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;

networks: {
base: {
url: “<https://base-sepolia-rpc.publicnode.com>”,
chainId: 84532,

},
},
};

Hardhat runs by finding the closest hardhat.config.js from the present listing, sometimes discovered on the root of your venture. 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 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 deal with

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 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
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 situations
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 principal() perform

Add a principal() perform for executing script.js. It’ll deal with any errors that will come up:

//…

async perform principal() {
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;
}
}

principal().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: Test 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 person 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 principal() to get the token steadiness

Replace principal() to execute getBalance() :

//…

async perform principal() {
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 much like the next in your console:

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

}
