The Unity SDK 3.0.0-beta.2 brings you an improved and customizeable Prefab_ConnectWallet, and adds in the Hyperplay connection option!
Email wallets are also now shown as input fields, we recommend you try it out with our recent Paper WalletProvider addition! Simply set it up from the prefab's Inspector. Local Wallets are shown as Guest wallets. We recommend using them as such, and have the user upgrade to a real "account" later on in the game's flow.
To connect using Hyperplay, you just have to connect to their launcher on the device you're running Unity on, and that's it! Install it from here.
