ConfigurableRoyaltyStandard

ConfigurableRoyaltyStandard

Library to house logic around the ERC2981 royalty standard. Contracts using this library should define a ConfigurableRoyaltyStandard.RoyaltyParams state var and public functions that proxy to the logic here. Contracts should take care to ensure that a public setRoyaltyParams method is only callable by an admin.
