I have a question: is it possible to mint two different collections under the same contract?
Is there any options on Manifold or either on OS too to “move” certain tokens to a different collection?
Or everything minted under a contract will go into the same collection without any chance to move them?
It depends on what you mean by move to different collections, if you want it to be done on chain you’ll need to do something like a BurnRedeem but if you’re just talking about how it’s viewed on Opensea this is just how a platform decides to sort this. I know creators have asked for collections to be merged before but it’s best to speak with Opensea’s support to check if this can be facilitated.
