First install the required packages:
Bash
NPM Installation-Sve-Div Hardhat ice ice ices
Installation of the contract to SEOLIA
You must mutual install the Seolia network before checking for the coin. You can do this with Hardhat "Deploy" feature:
Javascript
// seolial.js (examplection)
Const Ethhers = Requires (’Ethers’);
quoted (PloinpleContract’, {
Assyc Installation () {
Const service provider = new Ethers.povisors.povisors.peb3provider (window.etherreum);
Constinct Wallet = Waiting for the Service Provice Sgener ();
// install the contract and redeem the address
CONST TX = Waiting for the wallet.deployed (
‘htps://seoli-testet.co.th
{Date: ‘Your_Contract_Datanj
),
const deployed = tx.hash;
consume.log (’constinate installed: $ {deploydressed} );
}

Constinct Wallet = Waiting for the Service Provice Sgener ();
// install the contract and reception your address
Const TX = waiting for the wallet.deployed (
‘htps://seoli-testet.co.th
{Date: ‘Your_Contract_Datanj
),
const deployed = tx.hash;
consume.log (’const installed: $ {deploydressed} );
/// Check transformations on Seoli
Try {
Waiting for Verifying (she deported, service provider);
} citch (errorr) {
Console.Error (’Errifical Verification of Transaction:’, Error);
}
}
Function of Verifying (Adress, Service Provider) {
const shouirl = ‘
Const params = {{{ er
tittle,
Network: 'Seolia,
^
Try {
Const Answer = Waiting for FETCH (Seoliarapurl, {Mothod: 'Post’, Body: Json.stringify (Toms), Headers: {'Content Type’}–Contence: ‘Application/Jon’});
impressive.ok) {
console.log (’ transaction saccessful control’);
} Else {
throw an new error (’Error checking the transaction: $ {response.statust}');
}
} citch (errorr) {
Console.Error (’Errifical Verification of Transaction:’, Error);
}
}
Testing the function of function
To test the authentication function, you can create as simple testing pack with JEST:
Javascript
// seolial. test.js
Import {Verifyseolidressed} from ‘./well’;
Discribing (’Verifyseolidression’, () => => {>
it (’muust be trembling, async () => {), => eg
// Mock Seolia API API
Const reply = {
Data: {
Address: ‘You’re_deployed_dress’,
Network: ‘Seolia,
}
