|
## Install
|
|
|
|
Python-trezor requires 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](https://packaging.python.org/tutorials/installing-packages/).
|
|
|
|
### Quick installation
|
|
|
|
On a typical Linux / Mac / BSD system, you already have all you need.
|
|
Install `trezor` with:
|
|
|
|
```sh
|
|
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.
|
|
|
|
### Older Trezor One support
|
|
|
|
If your Trezor One is on firmware **1.6.3** or older, you will need HIDAPI support
|
|
for it to be recognized. That requires additional packages.
|
|
|
|
#### Debian / Ubuntu
|
|
|
|
On a Debian or Ubuntu based system, you can install these:
|
|
|
|
```sh
|
|
sudo apt-get install python3-dev python3-pip cython3 libusb-1.0-0-dev libudev-dev
|
|
```
|
|
|
|
#### Windows
|
|
|
|
On a Windows based system, you can install these (for more info on choco, refer to [this](https://chocolatey.org/install)):
|
|
|
|
```sh
|
|
choco install vcbuildtools python3 protoc
|
|
refreshenv
|
|
pip3 install protobuf
|
|
```
|
|
|
|
When installing the trezor library, you need to specify that you want
|
|
`hidapi`:
|
|
|
|
```sh
|
|
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:
|
|
|
|
```sh
|
|
pip3 install trezor[ethereum,hidapi]
|
|
```
|
|
|
|
### FreeBSD
|
|
|
|
On FreeBSD you can install the packages:
|
|
|
|
```sh
|
|
pkg install security/py-trezor
|
|
```
|
|
|
|
or build via ports:
|
|
|
|
```sh
|
|
cd /usr/ports/security/py-trezor
|
|
make install clean
|
|
```
|
|
|
|
### Building from source
|
|
|
|
Sometimes you might need to install the latest-and-greatest unreleased version
|
|
straight from GitHub. You will need some prerequisites first:
|
|
|
|
```sh
|
|
sudo apt-get install protobuf-compiler protobuf-dev
|
|
pip3 install protobuf
|
|
```
|
|
|
|
If you just need to install the package, you can use pip again:
|
|
```sh
|
|
pip3 install git+https://github.com/trezor/python-trezor
|
|
```
|
|
|
|
If you want to work on the sources, make a local clone:
|
|
|
|
```sh
|
|
git clone https://github.com/trezor/python-trezor
|
|
cd python-trezor
|
|
python3 setup.py prebuild
|
|
python3 setup.py develop
|
|
```
|
|
|
|
## 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/](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:
|
|
|
|
```sh
|
|
git submodule update --init --remote
|
|
```
|
|
|
|
Then, rebuild the protobuf messages and get `coins.json` by running:
|
|
|
|
```sh
|
|
python3 setup.py prebuild
|
|
```
|
|
|
|
To get support for BTC-like coins, these steps are enough and no further
|
|
changes to the library are necessary.
