Voltlog #154 – Making My Own Trezor Crypto Hardware Wallet

In this video I’m gonna show you how I build my own Trezor hardware wallet. If you would like to support the voltlog channel checkout the donations page where you will find my paypal address or different crypto wallet addresses.

If you encounter this error while trying to compile trezor firmware:

Traceback (most recent call last):
 File "nem_mosaics.py", line 6, in <module>
 from google.protobuf import json_format
ImportError: cannot import name json_format
Makefile:121: recipe for target 'nem_mosaics.h' failed
make: *** [nem_mosaics.h] Error 1

It can be fixed by installing googleapis-common-protos package like this:

sudo pip install googleapis-common-protos

This fix was posted in the comments section by a viewer, I verified and it works.
