Why was the coldcard in it? There’s a way to permanently link a coldcard to a RPi4? And why would one do that?
There is actually a repo from Coinkite to get HSM functionality out of your Coldcard.

I love this…
Doesn’t this turn it into a hot wallet then?
Yes and no.
The secrets are still on a hardware device but signing can be done without physical access.
But your coldcard is obviously not airgapped anymore.
