A username account keeps your XP, game scores, quests, and wallet connection together across devices.
If Phantom says connected but this app does not, connect in Phantom once, copy the restore code, then paste it here.
Username accounts are used first. Guest ID is only a temporary fallback until you create or sign into an account.
This app stores a temporary guest ID on this device so XP and settings can work before you create an account. If you attach Phantom, your wallet address stays connected to your username account. The app never needs your seed phrase or private key.
