Yep. They have a wallet that's available through early access right now, and I was invited. Says it's #selfcustody 

 Likely. I was hoping to catch the 👀 of someone who has experience with, or more technical knowledge with, their wallet or the principles behind it. The btc-through-email is a really neat function. 

 I hadn’t the time to fiddle with it. They published a lot of supporting information though… https://proton.me/wallet/security 

 I read through everything. Just hoped to find a bit of social proof along the way.

I guess it's all mostly the same anyway. 

 Fair enough. It’s currently restricted access. Once it’s opened to broader audience I guess you’ll get that social proof rather quickly
