RoyaltyFee

A fee to assess during a CryptoTransfer that changes ownership of an NFT. Defines the fraction of the fungible value exchanged for an NFT that the ledger should collect as a royalty. ("Fungible value" includes both ℏ and units of fungible HTS tokens.) When the NFT sender does not receive any fungible value, the ledger will assess the fallback fee, if present, to the new NFT owner. Royalty fees can only be added to tokens of type NON_FUNGIBLE_UNIQUE.
