I simply wanted to do the same checking process on my Ledger that comes as a prize for the BCA award.
I guess it’s a sensible idea being ultra paranoid toward a customised device that Betnomi knew was directed to a generic “well known user” of the forum.
I don't disagree with that, and you should check if for your own safety, especially after what is happening with Betnomi now. When you say "customized" and "tempered with", I thought you already saw or noticed something being off. But it seems to be just a hunch or a possibility, and you haven't actually found or checked for anything malicious yet.
