Verification of coin transactions on Seolia Network using Hardhat
As a developer, you are likely familiar with the Ethereum blockchain and its various APIs. He recently installed an intelligent contract on the Seolia network, a decentralized platform for the issue and trade of cryptocurrencies. However, before implementing any transaction, it is essential to ensure that your account is valid and compliant with network regulations.
In this article, we will guide you through the process of checking the coin with the help of Hardhat Toolset and interact with the Seolia API Key.
Set up the environment
To get started, you need to install the following addictions:
Hardhat: node.js package manager for Ethereum Development
Npx: Short manual marking to run NPM scripts with Node.js
Ethers.js: A library offering a simple way to interact with Ethereum blockchain
First install the required packages:
`Bash
NPM Installation-Save-Dev Hardhat ethers
`
Installation of the contract to SEOLIA
You must install the contract on the Seolia network before checking the coin. You can do this with your Hardhat “Deploy” feature:
`Javascript
// seolia.js (example contract)
Const Ethhers = Requires('Ethers');
contract ( ' PloinpleContract ' , { {
Async Installation() {
Const service provider = new Ethers.poviders.web3Provider(window.ethereum);
Const Wallet = WaitingServiceProvider.getSigners();
// install the contract and get its address
CONST TX = wallet waiting.deployed(
'
{Data: 'Your_Contract_Data'}
);
const deployaddress = tx.hash;
console.log(contract installed: ${deployaddress});
},
});
`
Replace “your_contract_data” with the actual data of the contract.
Verification of transactions in Seolia -n
To justify the coin, you must use the Hardhat Celify command. This interacts with the Seolia API key to retrieve the details of the transaction and confirm that they are valid:
`Javascript
// seolia.js (the same as before)
Async Installation() {
Const service provider = new Ethers.poviders.web3Provider(window.ethereum);
Const Wallet = WaitingServiceProvider.getSigners();
// install the contract and get its address
CONST TX = wallet waiting.deployed(
'
{Data: 'Your_Contract_Data'}
);
const deployaddress = tx.hash;
console.log(contract installed: ${deployaddress});
// Check transactions on Seolia
Try { Try {
Waiting for Verify Oil Address (deportation address, service provider);
} catch (error) {
Console.Error(‘Transaction Verification Error:’, Error);
} }
} }
Async Function VerifyOilAddress(Address, ServiceProvider) {
const seoliaapiurl = ‘
Const params = {{
title,
Network: ‘Seolia’,
};
Try { Try {
Const Answer = Waiting for FETCH(Seoliaapiurl, { Method: ‘Post’, Body: Json.stringify(Params), Headers: {‘ContentType’: ‘Application/Json’}});
if ( response . ok ) {
console.log(‘transaction successfully controlled’);
} Else {
throw a new error ( Error checking the transaction : $ { response . statustext } );
} }
} catch (error) {
Console.Error(‘Transaction Verification Error:’, Error);
} }
} }
`
Testing the verification function
To test the authentication function, you can create a simple test pack with JEST:
“ Javascript
// seolia.test.js
Import { VerifyOilAddress} from ‘./oil’;
Describe(‘VerifyAddress’, () => {{{
it(‘must be true if the transaction is certified’, async() => {{
// Mock Oil API Answer
Const reply = { Const reply = {
Data: {
Address: ‘Your_deployed_address’,
Network: ‘Seolia’,
},
};
Waiting for VeryPhysicalOilAddress(Response.data.address, {Environment: ‘Development’});
Expected ( true )
