Regarding the recent Proton Wallet, I respect their conscious effort to be transparent and open about the tradeoffs / threat model (especially in their recent blog posts; see below).

I just tested out the wallet, great work.

Though not perfect ATM, they seem to be on a good path so far in building a Bitcoin-only wallet to simplify sending and receiving Bitcoin for their 100 million Proton users.

Presently, they appear to use the Bitcoin Dev Kit (BDK; see below) as a dependency, with coinjoin and the Lightning Dev Kit (LDK) on their radar. Hopefully, we will see silent payments integrated down the line, too.

Nevertheless, as a Proton user, I look forward to seeing how the Proton Wallet evolves 🔥
