Yes, I was able to send to myself 105k sats onchain (+19.5k sats fee) ; and 22.5k via Lightning.
So a total of 147k when I only had 125k in that wallet.
This is bad, really bad for Muun.

Yeah... yikes. 😬
But. Good sat stack. Free onchain fee repayment! 😂
Exactly!
Got sats back! 🤣🤣
If they ever figure it out and set your balance back to negative, just delete the app. You never saw it!
Haha, that’s what I’m going to do. But even if the realize, how are they going to get a hold of me?
That’s the neat part… 
It was an accident and completely their fault, but consider returning the money. Muun is goofy, but they have helped tons of people get into Bitcoin and lightning and are generally positive for the space. If too many people rip them off, they will go out of business and take everyones' sats with them. That would be bad for the network and the individuals affected.
I’ll do something even better. I’m going to send them an email explaining what I did (so they can fix this) and offering to send the extracted funds back.
