Editorial reading note
The checked portions are Abstract; Specification in the pinned version. The original title is Non-Fungible Token Standard.
The specification tracks and transfers ownership of distinct NFTs and permits operators to manage a holder's NFTs. It requires ERC721 and ERC165 interfaces, with exceptions stated in the text. Use it to trace ownership and operator permissions for individual tokens; the interface does not by itself establish off-chain rights.
Reading level: spec_text; only the sections above were checked. Pinned version: 90b1b4f10634290c1e227d700554065c755f0816 (https://github.com/ethereum/ERCs/blob/90b1b4f10634290c1e227d700554065c755f0816/ERCS/erc-721.md). These notes explain normative requirements; they are not a full reading, implementation verification or security audit and do not establish implementation compliance.
