ERC-721 is a standard for non-fungible tokens (NFTs) on the Ethereum blockchain, which are unique and cannot be exchanged on a one-to-one basis like ERC-20 tokens. Each ERC-721 token has a distinct value and identity, making it ideal for representing ownership of unique digital assets such as artwork, collectibles, real estate, and more. The ERC-721 standard defines a set of rules for creating and managing these tokens, ensuring that they can interact seamlessly with other contracts and decentralized applications (dApps) on the Ethereum network. By providing a framework for uniqueness and indivisibility, ERC-721 has enabled the growth of the NFT market, empowering creators and users to tokenize and trade unique assets in a secure and transparent manner.
