  1. Grab the NFTokenID
    Example NFT 000C0000ACCB60DD01C1C54C54C8155CABDAAAF18D374E9616E5B76200000001
  2. Search the Ownership history of this NFT, to find the NFTokenMint Transaction
    Example TX E5CB61CECF5ADDA8C4C3C3AFE97ADB9AE181389470D0596A331A85A39DB3B34E
  3. Find the largest MemoData hex, and convert it from Hex to a String using the next tool.
  4. Grab the resulting JWT from the Hex decoding and head to jwt.io
    Example JWT
    eyJhbGciOiJFUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbnRlcm5hbF90b2tlbl9pZCI6IjAyMzAzMTUxNkQ1MTM2NEE0RTQ2NTQzMjMzMzMzNjMxMDAwMDAwMDAiLCJjb2xsZWN0aW9uX2lkIjoickpORDlYNFF4aUVpS0JaenFWdkZmZXZKQ01KV1FqVkdzayIsImNvbGxlY3Rpb25faXBmc19jaWQiOiJiYWZ5YmVpZ2RneHVhYjdxNDZsenNhdW4zZjR1N3Vmdm53eHcya3ZpdnppNWl6MmNqbWFsejJvbGlocSIsInN0YW5kYXJkX21pZ3JhdGlvbiI6dHJ1ZSwibWludGVyIjoickdrZWl5NDR1OUZiV25CU1JmOXFmdUtYZ1NZUGoxNjhTcyIsImlhdCI6MTY2NjI0ODg3NCwiaXNzIjoiU29sb2dlbmljIEZvdW5kYXRpb24ifQ.R15uCZztXdThkt0qPqKodJHrrg9Dl0PH9FbN-JwrOdXpaLO9Pm1ZZ20CazTRLmMAeeWUNBxyklbfRCMYKWqG-g
