ERC-721

The Ethereum token standard for non-fungible tokens (NFTs).

Definition

The Ethereum token standard for non-fungible tokens (NFTs). Unlike ERC-20 tokens where each one is identical, every ERC-721 token has a unique ID. It's the standard behind CryptoPunks, Bored Apes, and most Ethereum NFT collections. ERC-721 introduced the concept of provable digital uniqueness.
