Functions

royaltyInfo

Returns how much royalty is owed and to whom, based on a sale price that may be denominated in any unit of exchange. The royalty amount is denominated and should be paid in that same unit of exchange. NOTE: ERC-2981 allows setting the royalty to 100% of the price. In that case all the price would be sent to the royalty receiver and 0 tokens to the seller. Contracts dealing with royalty should consider empty transfers.
