On the Ethereum blockchain, a technical standard known as ERC-721 establishes the guidelines for producing and administering non-fungible tokens (NFTs). ERC-721 tokens are different and indivisible, unlike ERC-20 tokens, and they stand for discrete assets with unique features and ownership.
The use of NFTs based on the ERC-721 standard to represent digital artwork, collectibles, virtual properties, and other special goods on the blockchain has grown in popularity.
