The NFTs created after wrapping support the MCC standard, which means you can provide your Verified Collection Address (VCA).
To obtain your VCA, enter the hash of one of your NFTs in Solana Explorer and copy the Verified Collection Address.
One more hint: If you generate our own Hash List, please specify that the collection is not fixed, it’s open so you don’t have to update the hash list containing the new NFTs, for each new collection. You can do that by leaving a message for the Magic Eden Listing Operations team under "Anything else we should know?
Please open a Discord Ticket in case you have any issues and we will try and contact the marketplace support.
