ERC-721 Definition - Glossary

ERC-721 is a token standard for creating non-fungible tokens (NFTs) on the Ethereum blockchain, supporting unique digital assets.

ERC-721 is a token standard on the Ethereum blockchain, specifically designed for non-fungible tokens (NFTs). Unlike ERC-20 tokens, which are fungible and identical, ERC-721 tokens represent unique digital assets. Each ERC-721 token has a unique identifier and metadata, making it ideal for applications like digital art, collectibles, and gaming assets. This standard includes functions for transferring tokens, checking token ownership, and accessing token metadata. ERC-721's design ensures that each token can be individually tracked and authenticated. This has led to its widespread adoption in various NFT marketplaces and platforms, enabling the creation and exchange of unique digital items.
