I just opened a ledger up, its stupid easy to do. Why wouldn't they make this a sealed unit with and glue it to make it impossible to open without damaging? Also why would you not glue the entire circuit board? The entire board is covered in test pads which make it super easy to solder dodgy stuff onto.

At the price of an eSIM and a LTE modem (and of the stolen 100$M), destroying a glued casing and making your own costs next to nothing. Looking at the photos, even without the test pads soldering directly on the components seem pretty easy.

They could have just potted it. This is a standard manufacturing process that's been around since at least the early 20th century.

Last year there were ones going around with these eSIM modules in them and they appeared to have printed new 3D cases for them, so it's definitely something they have experimented with.

Even if it is still possible to do, doing it at scale becomes a lot more complex

I believe epoxy-filling them a-la IronKey is a good idea, but for longevity reasons, I'd prefer the rechargeable battery to be replaceable.

Maybe it increases the price quite a lot, IDK.

I had an old Ledger die recently and replaced it with a new one. Didn't even consider being potentially able to replace the battery, but it would have been nice.

On the plus side, I did get to do a "fire drill" of my recovery process, which did work, so that was nice.

I'm a large believer of long-living tools and things in general, so I prefer my tools to be repairable and maintainable.

Of course I can't achieve what I want all the time, but being able to use a fixed-function tool till some electronic component dies inside is way more attractive for me to send the same device to recycling or trash just because a part with limited life (and shorter time w.r.t. rest of the device in general) reaches ends of its life.

Access to battery terminals enables power side-channel attacks such as DPA and CPA.

Probably, but you can defend for them as well. We fixed those more than a decade ago, I believe.

different models are subject to different levels of physical security. for example, the Nano Gen5 is extremely hard to open without some form of physical damage

Depending on who is responsible for this, do you not think these people would have the ability to circumvent physical anti-tampering measures?

Not an excuse for ledger making a sub-par product to begin with...

why not make it transparent?

Sony SRF-39FP has a transparent case, designed to thwart contraband concealment. The radio often appears on the commissary lists of U.S. federal prisons, hence the "FP" suffix https://en.wikipedia.org/wiki/SRF-39 Sony D-FJ003FP, Sony WM-FX193FP, SONY SRF-M35FP

It's almost as if the cryptocurrency industry is just amateur LARP…
