NFT-Collection

Details

Getting Started

You can interact with the deployed testnet app here: https://nft-collection-uo3l.vercel.app/ To mint an NFT your wallet address must be whitelisted - to do this, please visit this Whitelist site that runs on Goerli as well: https://whitelist-dapp-goerli-eight.vercel.app

Prerequisites

Have Node.js installed on your computer. This project was developed using Node.js v18.7.0.

Have the Whitelist contract deployed on the network you want to use. See the Whitelist contract for more details.

Set up a goerli endpoint on Quicknode. See the Quicknode documentation for more details. Of course, you can use any other Ethereum endpoint instead.

Installing Dependencies for the Blockchain part

npm init --yes
npm install --save-dev hardhat
npx hardhat 

Select an empty hardhat config. JavaScript has been used originally as the language and the default options have been chosen for the rest. Copy and paste the text from the hardhat-config-copy.js file into the newly generated hardhat.config.js file after deleting its default content.

npm install @openzeppelin/contracts
npm install dotenv

Add private key and quicknode endpoint to .env file. See the .env-example file for more details. Run:

npx hardhat compile
npx hardhat run scripts/deploy.js --network goerli

Possible errors

If you get the following error:

Error HH600: HardhatError: HH600: The selected network "goerli" doesn't exist.

It means that you haven't set up a goerli endpoint on Quicknode. See the Quicknode documentation for more details. Of course, you can use any other Ethereum endpoint instead.

If you get the following error:

Error: Cannot find module '@nomicfoundation/hardhat-toolbox'

Install the missing dependency:

npm install @nomicfoundation/hardhat-toolbox

Error Private Key to long:

Invalid account: #0 for network: goerli - private key too long, expected 32 bytes

Check if you have copied the private key correctly. It should be 64 characters long. If it's still not working, check if you added a 0x prefix to the private key, either in your .env file or in the hardhat.config.js file. Also check if you've added a semicolon at the end of the private key in your .env file. If so: remove it.
