I wouldn't personally, let it be just your bitcoin wallet... or get a 2nd one to do other non Bitcoin stuff on it, but you do you.
If you want to go deep into the rabbit hole you can fork their code here and make whatever you want
https://github.com/Blockstream/Jade
buy the parts and then build your own case:
https://github.com/Blockstream/Jade/tree/master/diy
or flash it to a jade device...
if you want more 2FA type stuff I would say buy yourself a new yubikey during black friday (the latest ones, cause the old ones have a newly discovered exploit) and use that.
Java cards are hot right now, check out satochip if interested in that space
enjoy the journey
Already have a bunch of old hww's lying around so I thought the jade could maybe be used for something else too as it has Bluetooth and a camera. But couldn't find any 3rd party project/app so I'll just sell it as I don't want to invest time writing something.
Thanks for the input, javacards seem pretty fun have to check them out at one point.
I hear you, yeah I dont know of any 3rd party apps for Jade (probably a good thing).
I sa this a few days ago, maybe a fun project can be abusing an old andoird phone, as you will have full bluetooth and camera functionality ou of the box.
