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 🔥 - - - More Reading 📌 - Initial announcement: proton.me/blog/proton-wallet-launch - The wallet's security model: proton.me/blog/proton-wallet-security-model - Github repo: github.com/ProtonWallet/andromeda - Potential future dependencies: github.com/ProtonWallet/andromeda/commit/211dc5a86f20455cdba99e0a51a37a61ef70577c
