# Advanced Hardhat project for the NFT & Presale system

This project demonstrates an advanced Hardhat use case, integrating other tools commonly used alongside Hardhat in the ecosystem.

The project comes with a sample contract, a test for that contract, a sample script that deploys that contract, and an example of a task implementation, which simply lists the available accounts. It also comes with a variety of other tools, preconfigured to work with the project code.

Try running some of the following tasks:

```shell

npx hardhat accounts

npx hardhat compile

npx hardhat clean

npx hardhat test

npx hardhat node

npx hardhat help

REPORT_GAS=true npx hardhat test

npx hardhat coverage

npx hardhat run scripts/deploy.js

node scripts/deploy.js

npx eslint '**/*.js'

npx eslint '**/*.js' --fix

npx prettier '**/*.{json,sol,md}' --check

npx prettier '**/*.{json,sol,md}' --write

npx solhint 'contracts/**/*.sol'

npx solhint 'contracts/**/*.sol' --fix

```

# Etherscan verification

To try out Etherscan verification, you first need to deploy a contract to an Ethereum network that's supported by Etherscan, such as Ropsten.

In this project, copy the .env.example file to a file named .env, and then edit it to fill in the details. Enter your Etherscan API key, your Ropsten node URL (eg from Alchemy), and the private key of the account which will send the deployment transaction. With a valid .env file in place, first deploy your contract:

```shell

hardhat run --network ropsten scripts/deploy.js

```

Then, copy the deployment address and paste it in to replace `DEPLOYED_CONTRACT_ADDRESS` in this command:

```shell

npx hardhat verify --network ropsten DEPLOYED_CONTRACT_ADDRESS "Hello, Hardhat!"

```
