Coming over from the Ethereum ecosystem and haven't been able to find much information about integrating creator royalties into ERC721 contracts using rust or ink!. I know on Ethereum, the large marketplaces have royalty registry contracts that you can import and integrate in your ERC721 contract. Is this the way it is done on substrate-based blockchains as well(if so, could you point me in the direction of a few) or is there a different implementation, or none at all?
Appreciate your help!
