ERC-721
The technical standard most non-fungible tokens (NFTs) on Ethereum follow.
ERC-721 is a standard interface for non-fungible tokens, where each token is unique and individually identified, unlike interchangeable ERC-20 tokens.
This standard underlies most well-known NFT collections, defining how ownership and transfer of each individual, unique token is tracked on-chain.
Examples
- Most digital art and collectible NFT projects are issued as ERC-721 tokens.
- Unlike ERC-20 tokens, each ERC-721 token has its own unique identifier.
