bitbox02-firmware VS 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.

TIP: Use the BoM as well as the schematic.

As you can see, the default firmware of Coldcard is hardcoded with values d13e and cc10. We are going to change it to make it look like a benign USB device, more on it later. First, clone the original firmware from Github: https://github.com/Coldcard/firmware We now need to edit the file called ./stm32/COLDCARD/shared/usb.py: COINKITE_VID = 0xd13e CKCC_PID = 0xcc10

Software altered? You were supposed to download from source and flash it yourself. So why did you alter it? No one other than you could have altered it! https://github.com/Coldcard/firmware

Coldcard

Consider holding long term with a solution like this. Have you ever use a hardware wallet like a coldcard

Coldcard has many other security features as well. You can find more about them online. Probably the safest hard & cold wallet on the market right now. But most people don't buy it because of their $400 price tag. But definitely worth it for anyone holding more than a pretty penny.

You can check it

it’s a cold wallet that only holds BTC
