 Also what is dope about Start9 is that you can run Mutiny from your server separate from your phone.

"Instead, your StartOS server hosts the web app that you can access from any device on your local network or via TOR."

 That's dope indeed! 

 Yeah, you can have a private instance of it over tor off the server and another with your nsec in it on your phone. Swap between same or separate federations on different wallets for privacy etc.

zaps to cashu
cashu to fedi
fedi to fedi private lightning  

 That's some next level swapping mastery Ima be honest. 

 *Fedi in mutiny doesn't have LN address, so I use minibits which is cashu
*Once big enough balance in cashu I can confirm iou's are good by sending out of mint over lightning to fedi on mutiny which is multi party custodial and has my nsec
*Once fedi balance is say 200k sats then I would confirm fedi balance by opening a 200k channel on mutiny without my nsec, potentially connected to my own lightning node on my start9
