How to Use the getNFTData Function​

The getNFTData function retrieves data for an NFT based on its identifier. It returns a struct of type ISCNFT, which contains various properties of the NFT like the issuer, metadata, owner, and NFTID. To use this function, you need to create a function in your smart contract that calls getNFTData and processes its return value, as shown in the example contract below:

pragma solidity ^0.8.0;

import "@iota/iscmagic/ISC.sol";
import "@iota/iscmagic/ISCTypes.sol";

contract NFTMetadata {
    function fetchNFTData(uint256 tokenId) public view returns (ISCNFT memory nftData) {
        nftData = ISC.sandbox.getNFTData(ISCTypes.asNFTID(tokenId));
        return nftData;
    }
}
