Every Non-Fungible Token (NFT) is built from three essential technical components that work together to create a unique, verifiable digital asset.

The first element is the Contract Address (or Mint Address on Solana). This is the smart contract deployed on the blockchain that contains the rules governing the entire collection — such as minting limits, royalties, and transfer permissions.

The second element is the Token ID. This is a unique number assigned to each individual NFT within the collection. No two tokens share the same ID, making every NFT distinct even if they look visually similar.

The third and most important element is the Metadata URI (Uniform Resource Identifier). This is a link that points to a JSON file containing all the descriptive information about the NFT — name, description, image or media file, attributes, traits, creator details, and sometimes royalty settings.

Together, these three components give an NFT its identity, ownership history, and value. Understanding this anatomy is crucial because it explains how NFTs provide verifiable ownership and transparency — key features that make them powerful tools for social impact, digital art, certificates, and community projects.
