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 3.9 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, Trezor T version 2.1.0 and up, and all versions of the Trezor Safe family.
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 and bootloader older than 1.6.0 (including pre-2021 fresh-out-of-the-box units) will not be recognized, unless you install HIDAPI support (see below).
Installation options
-
Bluetooth: To support connecting to T3W1 or later models via Bluetooth, additional dependencies are needed. Install with:
pip3 install trezor[ble]
-
Ethereum: To support Ethereum signing from command line, additional packages are needed. Install with:
pip3 install trezor[ethereum]
-
Stellar: To support Stellar signing from command line, additional packages are needed. Install with:
pip3 install trezor[stellar]
-
Firmware-less Trezor One: If you are setting up a brand new Trezor One manufactured before 2021 (with pre-installed bootloader older than 1.6.0), 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]
To install all four, use pip3 install trezor[ble,hidapi,ethereum,stellar].
Distro packages
Check out Repology to see if your operating system has an up-to-date python-trezor package.
Running from source
Install the uv tool, checkout trezor-firmware from git,
and activate the uv environment:
git clone https://github.com/trezor/trezor-firmware
cd trezor-firmware
git submodule update --init --recursive
uv sync
source .venv/bin/activate
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
python/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.

Contributing
If you want to change protobuf 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
