What Problem Did the ERC-721 Standard Solve for the Crypto Domain?

ERC-721 solved the problem of representing unique, non-interchangeable assets on a blockchain. Before its creation, all tokens were assumed to be fungible.

ERC-721 introduced a standardized way to track individual ownership of distinct digital items, assigning a unique ID to each token. This innovation unlocked new use cases like digital collectibles, gaming items, and tokenized real-world assets, forming the basis of the modern NFT market.
