So I went back to poking at hardware wallets again today, I am done after literally an hour. The BIP 85 support for @BitBoxSwiss just absolutely blew my mind away at how horrible the entire architecture is, and illuminated a huge architectural flaw in the entire device I hadn't considered/realized that just blows my mind. And there is literally 0 defense for it beyond arguing that users must be treated like retarded an incompetent children. The entire feature isn't accessible without an external trigger from the software wallet on the host. WHY!?!??! The entire feature needs absolutely nothing whatsoever from the host. It sends nothing whatsoever back to the host. You enter an index on the device, you get shown a derived seed on the device to copy manually, you verify that seed on the device. That's it. That's the entire flow. Why in the fuck is that incredibly valuable feature gated behind whether or not some software wallet developer implements new code paths to trigger something that doesn't ever directly interact with his software in anyway whatsoever. Like holy fucking shit. All Bitbox users cannot access this feature without 1) using the Bitbox app and falling into default funnels that suck up your information or 2) developers of numerous other software wallets having to implement new code for no logical reason whatsoever. The same exact thing applies to the passphrase functionality. It isn't even accessible AT ALL without first flipping a device configuration flag through the software wallet on the host (welcome back to the funnel bleeding you of your information) when the only thing it will do with the host after applying the passphrase to the master key is everything that the software host has to support already by virtue of you using the Bitbox with it in the first place. Why on Earth are EITHER of these features gated behind a software wallet on a host externally triggering them? It makes zero sense. It does nothing but create a funnel pushing your users into your software that sucks up their personal information, with the only alternative being numerous other development teams taking the time to write new code they have to maintain for no logical reason. And yes, I'm sure this applies to numerous other hardware wallets out there that I don't realize/know right now, and I send the exact same degree of what the fuck to all of them as well.
