  1. Sir, thank you so much for this video…but if you can help me .. I want to make a contract ERC721A with Secondary Royalties but on Opensea ..how to make that ??

  2. Do I need to confirm separately for each NFT? Will royalties be valid on other networks as well? Such as, Avalanche. Also, thank you for the detailed information.
