The original wait_layout was unreliable, because there are no guarantees re order of arrival of the respective events. Still, TT's event handling is basically deterministic, so as long as the host sent its messages close enough to each other, the order worked out. This is no longer the case with the introduction of loop.spawn: TT's behavior is still deterministic, but now ButtonAck is processed *before* the corresponding wait_layout, so the waiting side waits forever. In the new process, the host must first register to receive layout events, and then receives all of them (so the number of calls to wait_layout must match the number of layout changes). DebugLinkWatchLayout message must be version-gated, because of an unfortunate collection of bugs in previous versions wrt unknown message handling; and this interests us because upgrade-tests are using wait_layout feature. |

trezorlib
Python library and command-line client for communicating with Trezor Hardware Wallet.
See https://trezor.io for more information.
Install
Python Trezor tools require Python 3.5 or higher, and libusb 1.0. The easiest
way to install it is with pip. The rest of this guide assumes you have
a working pip; if not, you can refer to this
guide.
On a typical system, you already have all you need. Install trezor with:
pip3 install trezor
On Windows, you also need to either install Trezor Bridge, or libusb and the appropriate drivers.
Firmware version requirements
Current trezorlib version supports Trezor One version 1.8.0 and up, and Trezor T version 2.1.0 and up.
For firmware versions below 1.8.0 and 2.1.0 respectively, the only supported operation is "upgrade firmware".
Trezor One with firmware older than 1.7.0 (including firmware-less out-of-the-box units) will not be recognized, unless you install HIDAPI support (see below).
Installation options
-
Firmware-less Trezor One: If you are setting up a brand new Trezor One without firmware, you will need HIDAPI support. On Linux, you will need the following packages (or their equivalents) as prerequisites:
python3-dev,cython3,libusb-1.0-0-dev,libudev-dev.Install with:
pip3 install trezor[hidapi] -
Ethereum: To support Ethereum signing from command line, additional packages are needed. Install with:
pip3 install trezor[ethereum]
To install both, use pip3 install trezor[hidapi,ethereum].
Distro packages
Check out Repology to see if your operating system has an up-to-date python-trezor package.
Installing latest version from GitHub
pip3 install "git+https://github.com/trezor/trezor-firmware#egg=trezor&subdirectory=python"
Running from source
Install the pipenv tool, checkout
trezor-firmware from git, and enter the pipenv shell:
pip3 install pipenv
git clone https://github.com/trezor/trezor-firmware
cd trezor-firmware
pipenv sync
pipenv shell
In this environment, trezorlib and the trezorctl tool is running from the live
sources, so your changes are immediately effective.
Command line client (trezorctl)
The included trezorctl python script can perform various tasks such as
changing setting in the Trezor, signing transactions, retrieving account
info and addresses. See the docs/ sub folder for detailed
examples and options.
NOTE: An older version of the trezorctl command is available for
Debian Stretch
(and comes pre-installed on Tails OS).
Python Library
You can use this python library to interact with a Trezor and use its capabilities in your application. See examples here in the tools/ sub folder.
PIN Entering
When you are asked for PIN, you have to enter scrambled PIN. Follow the numbers shown on Trezor display and enter the their positions using the numeric keyboard mapping:
| 7 | 8 | 9 |
| 4 | 5 | 6 |
| 1 | 2 | 3 |
Example: your PIN is 1234 and Trezor is displaying the following:
| 2 | 8 | 3 |
| 5 | 4 | 6 |
| 7 | 9 | 1 |
You have to enter: 3795
Contributing
If you want to change protobuf or coin definitions, you will need to regenerate
definitions in the python/ subdirectory.
First, make sure your submodules are up-to-date with:
git submodule update --init --recursive
Then, rebuild the protobuf messages by running, from the trezor-firmware top-level
directory:
make gen
To get support for BTC-like coins, these steps are enough and no further changes to the library are necessary.
