Do I need a wallet for Superclub?

No, not for the social side — clubs, posts, chat, friends and POINTs all work without one.

A wallet only comes in for the on-chain parts: buying a club drop, donating in CRETA, or holding NFTs. Connect one from Account → Wallet when you get there, and not before.

Whatever you do, nobody at Creta will ever ask for your wallet's recovery phrase or private key. Anyone who does is trying to rob you.
