Python library and commandline client for communicating with TREZOR Hardware Wallet
See https://trezor.io for more information
Install
-------
Python-trezor requires Python 3.3 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 <https://packaging.python.org/tutorials/installing-packages/>`_.
Trezor T only
~~~~~~~~~~~~~
On a typical Linux / Mac / BSD system, you already have all you need. Install ``trezor`` with:
.. code::
pip3 install --upgrade setuptools
pip3 install trezor
On Windows, you also need to install `libusb <https://github.com/libusb/libusb/wiki/Windows>`_
and the appropriate `drivers <https://zadig.akeo.ie/>`_. This is, unfortunately, a topic bigger
than this README.
Trezor One support
~~~~~~~~~~~~~~~~~~
In addition to the above, you need to install development headers for HIDAPI.
On a Debian or Ubuntu based system, you can install these:
.. code::
sudo apt-get install python3-dev python3-pip cython3 libusb-1.0-0-dev libudev-dev
When installing the `trezor` library, you need to specify that you want ``hidapi``:
.. code::
pip3 install --upgrade setuptools
pip3 install trezor[hidapi]
Ethereum support
~~~~~~~~~~~~~~~~
Ethereum requires additional python packages. Instead of ``pip3 install trezor``, specify
``pip3 install trezor[ethereum]``.
You can combine it with the above, to get both HIDAPI and Ethereum support:
.. code::
pip3 install trezor[ethereum,hidapi]
FreeBSD
~~~~~~~
On FreeBSD you can install the packages:
.. code::
pkg install security/py-trezor
or build via ports:
.. code::
cd /usr/ports/security/py-trezor
make install clean
Commandline 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/ <docs/>`_ sub folder for detailed examples and options.
NOTE: An older version of the ``trezorctl`` command is `available for Debian Stretch <https://packages.debian.org/en/stretch/python-trezor>`_ (and comes pre-installed on `Tails OS <https://tails.boum.org/>`_).
Python Library
--------------
You can use this python library to interact with a Bitcoin Trezor and use its capabilities in your application.
See examples here in the `tools/ <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
------------
Python-trezor pulls coins info and protobuf messages from `trezor-common <https://github.com/trezor/trezor-common>`_ repository. If you are
developing new features for Trezor, you will want to start there. Once your changes are accepted to ``trezor-common``, you can make a PR
against this repository. Don't forget to update the submodule with:
.. code::
git submodule update --init --remote
Then, rebuild the protobuf messages and get ``coins.json`` by running:
.. code::
python3 setup.py prebuild
To get support for BTC-like coins, these steps are enough and no further changes to the library are necessary.
