ERC-721

The ERC-721 standard differs significantly from the other Ethereum token standards ERC-20 and ERC-223. It describes a token that is not interchangeable. This means that each token is completely different, and each token has a different value to different users. One way to understand this token is to recall CryptoKittes. Each digital cat is independent, and its value depends on its scarcity and user's desire to buy.

ERC-721 tokens can be used on any exchange, but token value is "determined by the uniqueness and scarcity of each token." The interface functions specified in the standard include name, symbol, totalSupply, balanceOf, ownerOf, approve, takeOwnership, transfer, tokenOfOwnerByIndex, and tokenMetadata. It also defines two events: Transfer and Approval. Gerald Nash's article explains the concept of interchangeability well.
