This project lets you deploy a whitelist contract and an NFT contract where whitelisted users can mint NFTs for free while others need to pay.

• Whitelist system with a maximum number of allowed addresses.
• An NFT (ERC-721) contract with the following functionalities:
  • Limited total supply (20 NFTs).
  • 1 NFT per transaction rule.
  • Whitelisted users can mint for free.
  • Non-whitelisted users must pay 0.01 ETH to mint.

1. Clone this repository.
2. Navigate to the hardhat directory.
3. Set up environment variables by creating a .env file with the following entries:

PRIVATE_KEY="your_metamask_private_key"
RPC_URL="your_quicknode_http_provider_link"
ETHERSCAN_API_KEY="your_etherscan_api_key"

1. Install the required npm packages:

npm install
npm install @openzeppelin/contracts
npm install dotenv

2. Deploy the Whitelist contract:

npx hardhat run scripts/deploy.js --network sepolia

3. Take note of the contract address of the deployed Whitelist.

4. Replace the placeholder address in deploy-nft.js with your Whitelist contract address.

5. Deploy the NFT contract:

npx hardhat run scripts/deploy-nft.js --network sepolia

6. Interact with the contracts via Etherscan (Sepolia Testnet) or programmatically through web3 or ethers.js libraries.

1. Use Sepolia Etherscan to connect your wallet and interact with the Whitelist contract's "addAddressToWhitelist" function.
2. Now, interact with the NFT contract's mint function without sending any ETH.

1. Use Sepolia Etherscan to connect your wallet and interact with the NFT contract's mint function.
2. You'll need to send exactly 0.01 ETH for the minting to succeed.

• Always ensure you're using a testnet account for deployment to avoid any loss of real funds.
• Keep your private key and other environment variables confidential. Avoid publishing or sharing your .env file.
