What is the primary purpose of the Hardhat framework in Ethereum development?

To replace Solidity with a new programming language for writing smart contracts

To provide a visual editor for designing decentralized applications

To provide a flexible development environment with task automation and debugging for smart contracts

To serve as a standalone Ethereum client that mines blocks and validates transactions

Which of the following is a core feature of the Truffle framework?

Built-in support for writing tests in JavaScript and Solidity

Automatic deployment to any cloud provider without configuration

A built-in wallet for storing Ether and signing transactions

A graphical interface for designing smart contract logic

A team is deploying a smart contract to a public testnet. They need to automate the deployment so that the same script can be run against different networks without changing code. The project uses Hardhat. Which approach should they take?

Create a separate deployment script for each network and manually edit the RPC URL each time.

Define network configurations in hardhat.config.js and write a deployment script that uses the network name passed via the --network flag.

Hardcode the testnet RPC URL and private key in the deployment script and run it with node deploy.js.

Use Truffle's migrations and set the network in the truffle-config.js file, then run truffle migrate --network testnet.
