How about using parseEther so user does not have to use an external faucet for development, like you did in the waver portal

const nftContract = await nftContractFactory.deploy({
    value: hre.ethers.utils.parseEther('0.001'),
});

This would also be necessary I think

// We need to pass the name of our NFTs token and it's symbol.
  constructor() payable ERC721 ("SquareNFT", "SQUARE") {
    console.log("This is my NFT contract. Woah!");
  }

Kudos! 🍻

Amazing Stuff !! ✨✨

hardhat-config-js have a symbol ` which should be removed

amazing!, thank you

accounts: ['YOUR_PRIVATE_RINKEBY_ACCOUNT_KEY'] which private key is it ( is it the rinkbey test network private key on my metamask wallet or is it something else?

@cl-rs yes the private key on your metamask wallet.

⚠️ Please make sure to not commit hardhat.config.js to git.

If you want to commit to git, use dotenv.

hardhat.config.js

...
require('dotenv').config();
...

module.exports = {
  solidity: ...,
  networks: {
    rinkeby: {
      url: process.env.RINKEBY_URL,
      accounts: [process.env.PRIVATE_KEY],
    },
  },
};

Create a file named .env in the source of the project with the following content

RINKEBY_URL=[REPLACE_BY_YOUR_ALCHEMY_URL]
PRIVATE_KEY=[REPLACE_BY_YOUR_METAMASK_PRIV_KEY]

Finally run npm instal env.

I'm not sure if this was necessary, but I added the 0x prior to the account key:

accounts: [0x${PRIVATE_RINKEBY_ACCOUNT_KEY}]

If yours isn't working, this might be why. Didn't try it without, so not sure if this is just common sense or if it was unnecessary.

big thanks mate!

In hardhat.config.js > line 3 > module.export = {

It should be module.exports = {
