v23_myNFTName_42 - Project v, nft type 2, schema version 3, metadata myNFTName_42

Known schemas

• s01 - SkeyNetwork device key (version 1)
• g01 - Go2NFT token (version 1)
• b01 - SkeyBox certificate (version 1)
• tt1 - SkeyTix ticket (version 1)
• tp1 - SkeyTix occasional NFT (version 1)
• g02 - Go2NFT token (version 2)

Special cases

• <address>_<timestamp> - is treated as s01
• 1_<cid> - is treated as g01
