Warpcast

Trying to add my SOL wallet to Warpcast and this is the process?  Enter my private key?  Basically goes against best practices.

Why can't it prompt Phantom and just let me sign?

Where are you being asked to do this? This is not how it works, you should just see a prompt to connect Phantom.

After starting this process.  This is the screen after clicking to verify another address from the app settings
