Example Request and Response

Prerequisites

Before making requests with QUBIT® SDK, you must have it installed.

npm install @nest25/evm-chains-lib
OR
yarn add @nest25/evm-chains-lib

Request

Here is an example of how to make a deployContract request using the QUBIT® SDK:

// import the QUBIT SDK
const { ERC20 } = require('@nest25/evm-chains-lib');

// create a new instance of the ERC20 class
const erc20 = new ERC20();

// define the main function
const main = async () => {
    // call the deployContract method
    const contract = await erc20.deployContract('klay','your-private-key',"testErc20","TEST");

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

Response

Contract deployed at 0xCE9d9f032587f6680A061896e28d51641a155E9B. Transaction hash: 0x0a1619c524cd447b19957c31862b6e4a397ccce03588712e28bb37619d26c86e
