Editorial reading note
The checked portions are Abstract; Specification in the pinned version. The original title is Semi-Fungible Token.
The specification models semi-fungible tokens through ID, SLOT and VALUE and is compatible with ERC721. Values under different IDs in the same SLOT are treated as interchangeable, with corresponding value-transfer and approval semantics. Contracts must implement ERC3525, ERC721 and ERC165. Check identity, grouping and value separately; interchangeability within a SLOT does not establish identical off-chain rights.
