trezor-hardware VS bitbox02-firmware

However if you want, you can open it up and then 3d-print a new case.

If you want to repair, here is the description of the hardware: https://github.com/trezor/trezor-hardware/blob/master/electronics/trezor_model_t/index.md

Trezor is completely open hardware and open software. That means you don't have to trust, you can verify. You can even build everything yourself if you wish to prevent potential supply chain attacks.

Trezor is fully open source. Software, Firmware, PCB Schematics even the plastic case design! The whole shabang. Yes, this means you can build your own trezor if you wanted to. That's the kind of hardcore security dedication that we should support.

You can also build the entire Trezor hardware wallet yourself. The files for the 3d printable case is on Trezor's github, along with the schematics for the circuit boards and all of the little electrical parts needed to make it. https://github.com/trezor/trezor-hardware https://github.com/trezor/trezor-firmware

I'm looking at this, you can see a comparison when you scroll down: https://bitbox.swiss/bitbox02/

Bitbox02 - https://bitbox.swiss/bitbox02/

I also implemented BIP-85 just recently.

Here's the repository for the firmware of BitBox02: https://github.com/digitalbitbox/bitbox02-firmware

Complementary to that, you can also download the official release from https://github.com/digitalbitbox/bitbox02-firmware/releases and install it manually using command line tools, after verifying it is legit by reproducing it. Or build the app yourself after checking that the bundled firmware is correct.

At the bottom of this page, they concisely explain what they mean for each entry in the table and why they give that specific score. For this in particular, they consider the setup easier because you can backup to an (offline) SD card instead of writing it down manually.

I decided on this: https://shiftcrypto.ch/bitbox02/

There you go: https://github.com/digitalbitbox/bitbox02-firmware/pull/1069

The firmware code is open source and can be found here. The official releases are built from this code in a reproducible fashion. The community is able to verify that currently the only two ways of exporting the seed are via the 24 words displayed on the BitBox02 screen or onto a microSD card inserted directly into the device. If there are other unintended ways, it might be a bug, and should be sent to us as part of our bug bounty program.
