You may be interested in this other project I'm developing. I need to make some changes and improve its security model (will be done within the next days), but it is a very nice and fun alternative to metal:

Hardware wallets have become targeted devices and the incentive to tamper them grows at the same pace that the price of bitcoin. The most terrible part of this is that a compromised device can remain sleeping until a succulent price is achieved. Those few sats worth dollars 5 years ago may have multiplied its value.
The only reliable solution, now that bitcoin is widespread, is relaying both on FOSS, Open Hardware and multipurpose hardware without internet connection like vintage devices (game consoles, mp3 players, graphic calculators, PDAs)
Following this philosophy I am developing some projects, that I'm proud to recognize that they are very cool. For instance, I have implemented @npub17ty…3mgl to run on a Nintendo DSi console: https://github.com/ndssigner/nds-signer
