// import the QUBIT SDK
const { ERC721 } = require('@nest25/evm-chains-lib');

// create a new instance of the ERC721 class
const erc721 = new ERC721();

// define the main function
const main = async () => {
    // call the deployContract function
    const contract = await erc721.deployContract(
        'klay',
        'your-private-key',
        'testErc721',
        'TEST',
    );

    // print the contract address and transaction hash
    console.log(`Contract deployed at ${contract.address}. Transaction hash: ${contract.deployTransaction.hash}`);
};
// call the main function
main();
