ERC-721 Tokens Explained: Your Guide to Unique Digital Assets & NFTs
ERC-721 tokens are a type of non-fungible token (NFT) that exist on the Ethereum blockchain. Unlike traditional cryptocurrencies such as Bitcoin or Ethereum itself, which are fungible and interchangeable, ERC-721 tokens are unique and cannot be replaced or exchanged on a one-to-one basis. Each token carries specific information that distinguishes it from others, making it ideal for representing ownership of digital collectibles, art and various other assets.
Understanding the components of ERC-721 tokens can enhance your grasp of how they function:
-

-
Metadata: Each ERC-721 token can contain metadata, which provides detailed information about the asset it represents. This can include images, descriptions and other attributes that define the collectible.
-
Unique Identifiers: Each token has a unique identifier that sets it apart from other tokens. This identifier is crucial for proving ownership and authenticity.
-
Transferability: ERC-721 tokens can be transferred between users, allowing for trading and selling within various marketplaces.
