Google is taking more and more the direction of apple's sandbox policy. I can confirm there is no issue installing it in Graphene.
But hey, that popup might be right. Anything you install is potentially harmful. Don't thrust, verify https://github.com/RoboSats/robosats
I have it up and running on my Graphene phone already. My other pixel is soon to follow.
Robosats is great btw, thank you. I have completed a couple trades already 🤙
