The provided code implements a Solidity smart contract for managing non-fungible tokens (NFTs) on the Ethereum blockchain. Here's a brief explanation of what the code does: 1. Contract Initialization: The contract is initialized with the name "MyNFT" and the symbol "MNFT". 2. Minting Tokens: The contract owner can mint new NFTs and assign them to specific recipients. Each token has a unique identifier (token ID) that increments with each minting. 3. Burning Tokens: The contract owner can burn (delete) existing NFTs by their token IDs. This removes the tokens from circulation. 4. Total Supply: The contract provides a function to query the total number of tokens minted. Overall, this contract provides basic functionality for minting, burning, and querying NFTs. It can be deployed on the Ethereum network and interacted with using Ethereum wallets like MetaMask. To set up and test this contract using Hardhat: 1. Install Hardhat and initialize a new project: bash Copy code npm install --save-dev hardhat npx hardhat 2. Install the required dependencies: bash Copy code npm install @openzeppelin/contracts 3. Replace the content of contracts/MyNFT.sol in your Hardhat project with the provided contract code. 4. Write tests in the test/ directory to verify the functionality of the contract. 5. Compile the contract: bash Copy code npx hardhat compile 6. Test the contract: bash Copy code npx hardhat test 7. Deploy the contract to a testnet or local Ethereum network: bash Copy code npx hardhat run scripts/deploy.js Make sure to replace the placeholder content in deploy.js with the actual deployment logic.

Solidity smart contract named Mintify, implements an ERC721 token with minting functionality. It allows users to mint NFTs by paying a specified price per NFT. The contract also supports whitelisting functionality, where whitelisted users can mint tokens at a different price. The contract owner can set various parameters such as the base URI, mint price, whitelist price, maximum supply, and maximum tokens per wallet. ## Features - Price tiers for minting: `mintPrice` and `whitelistPrice` - Maximum supply limit: `maxSupply` - Maximum mints per wallet limit: `maxPerWallet` - Base URI for token metadata: `baseURI` - Whitelist for certain addresses: `whitelisted`
