1. Smart Contract 📜

The code that creates and manages the NFT.

// Simple NFT Contract
contract MyNFT is ERC721 {
    uint256 public tokenCounter;
    
    constructor() ERC721("My NFT", "MNFT") {
        tokenCounter = 0;
    }
    
    function mint() public {
        _safeMint(msg.sender, tokenCounter);
        tokenCounter++;
    }
}

2. Token ID 🔢

Unique identifier for each NFT.

Token #0, Token #1, Token #2...
Used to track ownership
Cannot be duplicated

3. Metadata 📋

Information about the NFT stored as JSON.

{
  "name": "Cool Dragon #123",
  "description": "A legendary dragon from the blockchain",
  "image": "ipfs://QmX...abc",
  "attributes": [
    {
      "trait_type": "Rarity",
      "value": "Legendary"
    },
    {
