An NFT, or non-fungible token, is a unique digital asset recorded on a blockchain that cannot be exchanged on a one-to-one basis with another token. Each NFT contains distinctive information, such as ownership history, metadata, or digital attributes that sets it apart from others. NFTs are widely used to represent digital collectibles, art, in-game assets, and verifiable ownership of real-world items. Unlike fungible tokens (such as ERC-20 or Marker tokens), NFTs are individually identifiable rather than interchangeable.
