j"19HxigV4QyBv3tHpQVcUEQyq1pzZVdoAutM7If you want to mint a collection of 1satordinal nfts, afaik, you can use @ZoideNFT or https://1satminter.vercel.app/
Collections are important as they allows the nfts in a collection to be verified that they were created by the original collection creator.
Anyone can add an ordinal to a known collectionID (e.g b568893d6fdc2932cbfb9e9ea6da0af7077bf6d419a8fd0f11f319f5181c7852_0 the txid of the collection origin inscription plus _0 the output index)
The collection origin inscription and all collection items should be created using the same funding wallet, thus ensuring they are signed with the same sigma signature, and verifiable.
Marketplaces should check that any 1satordinal item that claims to be part of a collection does in fact share the same sigma address as the collection origin inscription.
