ERC-721

ERC-721 is a technical standard for non-fungible tokens (NFTs) on the Ethereum blockchain. It defines a set of rules and requirements that allow for the creation and ownership of unique digital assets that are indivisible and irreplaceable. Each ERC-721 token is assigned a unique identifier, making it impossible for it to be duplicated or exchanged for another token. This makes ERC-721 ideal for representing assets that have unique qualities, such as digital art, collectibles, or game items. ERC-721 has gained popularity due to the growing interest in NFTs and their potential as a new asset class.
