This document is about the details of the ERC721 asset namespace and reference for CAIP-19.
In CAIP-19 a general asset identification scheme is defined. This is the implementation of CAIP-19 for ERC721 (referencing NFT tokens).
See CAIP-19.
The asset namespace is called "erc721" as in ERC721. It reference erc721 tokens (NFT) in the eip155 namespace (cf. CAIP3).
The Asset Reference format is the smart contract address of the erc721 token in the current chain_id.
The Token Id format is the NFT Identifier of the erc721 specification in the current chain_id.
The smart contract address strives for uniqueness for any erc721 tokens in the chain_id scope.
