I think this TTGO has wifi connection embedded? Huh

How can anybody use this to store your private keys?

I'm pretty sure (though couldn't find a quick confirmation) that even when there's wifi hardware available, it isn't enabled, no driver loaded, no wifi initialized or explicitly disabled. It wouldn't make sense to have such an attack vector open when you can disable this potential connectivity.

Or the other way round, if you fear such a DIY Jade could maliciously leak your wallet secrets via wifi, the code is open-source, as far as I've seen the firmware is reproducable. Inspect the code for shady stuff. The Jade clone can't guess your or other wifi's passwords.

I have the same strategy with my DIY PiTrezor which I run on a Pi Zero W. As wifi and/or Bluetooth can't be used with a basically Trezor One firmware, there's a) no driver for wifi or Bluetooth in PiTrezor's firmware and b) I disable explicitly both wireless modules in the Pi Zero's boot config. That's safe enough for me and my PiTrezor is more an experimental project, no valuable wallet on it.

I wish there was a DIY device that by default has no wifi at all...
