In the Read API, the indexing of NFT asset IDs is usually based on the smart contract address and the unique identifier of the asset (such as Token ID).\n\nFirstly, the smart contract address is the interface between the NFT asset and the blockchain network, used to identify a specific asset contract. Each smart contract address is associated with a unique asset, so in the Read API, the corresponding NFT asset can be quickly located through the smart contract address.\n\nSecondly, the unique identifier of the asset (such as Token ID) is a distinguishing feature for each NFT.
