Checking coin transactions on the seolia network using hardhat
As a developer, you are probably familiar with Blockchain Ethereum and its various APIs. Recently, you have implemented a smart contract on the Seoli network, which is a decentralized platform for issuing and negotiating cryptocurrency assets. However, before making transactions, it is essential to ensure that your account is valid and compatible with network regulations.
In this article, we will guide you in the process of checking your currency using the Hardhat tool set and interact with the Seoli API key.
Configuring the environment
For starters, you need to have the following facilities installed:
hardhat: a node.js package manager for the development of Ethereum
npx: Short notation to execute NPM scripts with node.js
ETHERS.JS: A library that provides a simple way to interact with Blockchain Ethereum
First, install the necessary packages:
`Bash
NPM Install-SAVE-DEV HARDHAT ETHINES
`
Implementing the contract in Seolia
Before checking your currency, you need to implement your contract on the Seoli network. You can do this using Hardhat’s implant 'function:
JavaScript
// seolia.js (example contract)
Constte Ethers = Requires (‘Éters’);
Contract (‘Examplecontract’, {
Async Implant () {
Consta Provider = new Ethers.Providers.Web3Provider (Window.ethereum);
CONST WALLET = WAIT Provider.get Signer ();
// Implant the contract and obtain your address
CONST TX = WAITING WALLET.DECROYED (
‘
{Date: ‘Your_Contract_Data’}
);
Constt ImplantDRESS = TX.HASH;
console.log (contract implemented to: $ {implantdress});
},
});
`
Replace your_contract_data with the actual data of your contract.
Verifying transactions in Seolia
To check your currency, you need to use the Hardhat Verify command. This will interact with the seolian API key to recover transaction details and confirm that they are valid:
`JavaScript
// seolia.js (same as before)
Async Implant () {
Consta Provider = new Ethers.Providers.Web3Provider (Window.ethereum);
CONST WALLET = WAIT Provider.get Signer ();
// Implant the contract and obtain your address
CONST TX = WAITING WALLET.DECROYED (
‘
{Date: ‘Your_Contract_Data’}
);
Constt ImplantDRESS = TX.HASH;
console.log (contract implemented to: $ {implantdress});
// Check the transactions in seolia
to try {
Wait for verified andLaAddress (implant, provider);
} catch (error) {
console.error (‘error checking the transaction:’, error);
}
}
ASSINCROONE FUNCTION VERIFIEDSOOLAADDRESS (Address, Provider) {
CONST Seoliaapiurl = ‘
CONST PARAMS = {
address,
Network: ‘Seolia’,
};
to try {
CONST Response = Wait to search (Seoliaapiurl, {Method: ‘Post’, Body: Json.Stingify (Params), Headers: {‘Content-Type’: ‘Application/JSON’}});
if (answer.ok) {
console.log (‘transaction successfully verified’);
} other {
Release a new error (transaction check error: $ {response.statustext});
}
} catch (error) {
console.error (‘error checking the transaction:’, error);
}
}
`
Testing the verification function
To test the check function, you can create a simple test suite using the jest:
`JavaScript
// seolia.test.js
Import {VerifySeoliaaddress} of ‘./seolia’;
Describe (‘VerifySeoliaaddress’, () => {
He (‘must return true if the transaction is verified’, Async () => {
// mock seolia api response
CONST Response = {
data: {
Address: ‘Your_Deployred_address’,
Network: ‘Seolia’,
},
};
Wait for VerifiedSeoliaaddress (Response.data.address, {Environmental: ‘Development’});
Wait (true).
