        "description": "python-trezor\n=============\n\n[![image](https://travis-ci.org/trezor/python-trezor.svg?branch=master)](https://travis-ci.org/trezor/python-trezor)\n\n[![image](https://badges.gitter.im/trezor/community.svg)](https://gitter.im/trezor/community)\n\nPython library and commandline client for communicating with TREZOR\nHardware Wallet\n\nSee <https://trezor.io> for more information\n\nInstall\n-------\n\nPython-trezor requires Python 3.3 or higher, and libusb 1.0. The easiest\nway to install it is with `pip`. The rest of this guide assumes you have\na working `pip`; if not, you can refer to [this\nguide](https://packaging.python.org/tutorials/installing-packages/).\n\n### Trezor T only\n\nOn a typical Linux / Mac / BSD system, you already have all you need.\nInstall `trezor` with:\n\n```sh\npip3 install --upgrade setuptools\npip3 install trezor\n```\n\nOn Windows, you also need to install\n[libusb](https://github.com/libusb/libusb/wiki/Windows) and the\nappropriate [drivers](https://zadig.akeo.ie/). This is, unfortunately, a\ntopic bigger than this README.\n\n### Trezor One support\n\nIn addition to the above, you need to install development headers for\nHIDAPI.\n\nOn a Debian or Ubuntu based system, you can install these:\n\n```sh\nsudo apt-get install python3-dev python3-pip cython3 libusb-1.0-0-dev libudev-dev\n```\n\nWhen installing the trezor library, you need to specify that you want\n`hidapi`:\n\n```sh\npip3 install --upgrade setuptools\npip3 install trezor[hidapi]\n```\n\n### Ethereum support\n\nEthereum requires additional python packages. Instead of\n`pip3 install trezor`, specify `pip3 install trezor[ethereum]`.\n\nYou can combine it with the above, to get both HIDAPI and Ethereum\nsupport:\n\n```sh\npip3 install trezor[ethereum,hidapi]\n```\n\n### FreeBSD\n\nOn FreeBSD you can install the packages:\n\n```sh\npkg install security/py-trezor\n```\n\nor build via ports:\n\n```sh\ncd /usr/ports/security/py-trezor\nmake install clean\n```\n\nCommand line client (trezorctl)\n------------------------------\n\nThe included `trezorctl` python script can perform various tasks such as\nchanging setting in the Trezor, signing transactions, retrieving account\ninfo and addresses. See the [docs/](docs/) sub folder for detailed\nexamples and options.\n\nNOTE: An older version of the `trezorctl` command is [available for\nDebian Stretch](https://packages.debian.org/en/stretch/python-trezor)\n(and comes pre-installed on [Tails OS](https://tails.boum.org/)).\n\nPython Library\n--------------\n\nYou can use this python library to interact with a Bitcoin Trezor and\nuse its capabilities in your application. See examples here in the\n[tools/](tools/) sub folder.\n\nPIN Entering\n------------\n\nWhen you are asked for PIN, you have to enter scrambled PIN. Follow the\nnumbers shown on TREZOR display and enter the their positions using the\nnumeric keyboard mapping:\n\n<table>\n<tr><td>7<td>8<td>9\n<tr><td>4<td>5<td>6\n<tr><td>1<td>2<td>3\n</table>\n\nExample: your PIN is **1234** and TREZOR is displaying the following:\n\n<table>\n<tr><td>2<td>8<td>3\n<tr><td>5<td>4<td>6\n<tr><td>7<td>9<td>1\n</table>\n\nYou have to enter: **3795**\n\nContributing\n------------\n\nPython-trezor pulls coins info and protobuf messages from\n[trezor-common](https://github.com/trezor/trezor-common) repository. If\nyou are developing new features for Trezor, you will want to start\nthere. Once your changes are accepted to `trezor-common`, you can make a\nPR against this repository. Don't forget to update the submodule with:\n\n```sh\ngit submodule update --init --remote\n```\n\nThen, rebuild the protobuf messages and get `coins.json` by running:\n\n```sh\npython3 setup.py prebuild\n```\n\nTo get support for BTC-like coins, these steps are enough and no further\nchanges to the library are necessary.\n\n\n# Changelog\nAll notable changes to this project will be documented in this file.\n\nThe format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/).\n\n_At the moment, the project does __not__ adhere to [Semantic Versioning](http://semver.org/spec/v2.0.0.html). That is expected to change with version 1.0._\n\n\n## [0.10.2] - 2018-06-21\n[0.10.2]: https://github.com/trezor/python-trezor/compare/v0.10.1...v0.10.2\n\n### Added\n- `stellar_get_address` and `_public_key` functions support `show_display` parameter\n- trezorctl: `stellar_get_address` and `_public_key` commands for the respective functionality\n\n### Removed\n- trezorctl: `list_coins` is removed because we no longer parse the relevant protobuf field\n  (and newer Trezor firmwares don't send it) [#277]\n\n### Fixed\n- test support module was not included in the release, so code relying on the deprecated `ckd_public` module would fail [#280]\n\n## [0.10.1] - 2018-06-11\n[0.10.1]: https://github.com/trezor/python-trezor/compare/v0.10.0...v0.10.1\n\n### Fixed\n- previous release fails to build on Windows [#274]\n\n## [0.10.0] - 2018-06-08\n[0.10.0]: https://github.com/trezor/python-trezor/compare/v0.9.1...v0.10.0\n\n### Added\n- Lisk support [#197]\n- Stellar support [#167], [#268]\n- Wanchain support [#230]\n- support for \"auto lock delay\" feature\n- `TrezorClient` takes an additional argument `state` that allows reusing the previously entered passphrase [#241]\n- USB transports mention udev rules in exception messages [#245]\n- `log.enable_debug_output` function turns on wire logging, instead of having to use `TrezorClientVerbose`\n- BIP32 paths now support `123h` in addition to `123'` to indicate hardening\n- trezorctl: `-p` now supports prefix search for device path [#226]\n- trezorctl: smarter handling of firmware updates [#242], [#269]\n\n### Changed\n- reorganized transports and moved into their own `transport` submodule\n- protobuf messages and coins info is now regenerated at build time from the `trezor-common` repository [#248]\n- renamed `ed25519raw` to `_ed25519` to indicate its privateness\n- renamed `ed25519cosi` to `cosi` and expanded its API\n- protobuf messages are now logged through Python's `logging` facility instead of custom printing through `VerboseWireMixin`\n- `client.format_protobuf` is moved to `protobuf.format_message`\n- `tools.Hash` is renamed to `tools.btc_hash`\n- `coins` module `coins_txapi` is renamed to `tx_api`.  \n  `coins_slip44` is renamed to `slip44`.\n- build: stricter flake8 checks\n- build: split requirements to separate files\n- tests: unified finding test device, while respecting `TREZOR_PATH` env variable.\n- tests: auto-skip appropriately marked tests based on Trezor device version\n- tests: only show wire output when run with `-v`\n- tests: allow running `xfail`ed tests selectively based on `pytest.ini`\n- docs: updated README with clearer install instructions [#185]\n- docs: switched changelog to Keep a Changelog format [#94]\n\n### Deprecated\n- `ckd_public` is only maintained in `tests.support` submodule and considered private\n- `TrezorClient.expand_path` is moved to plain function `tools.parse_path`\n- `TrezorDevice` is deprecated in favor of `transport.enumerate_devices` and `transport.get_transport`\n- XPUB-related handling in `tools` is slated for removal\n\n### Removed\n- most Python 2 compatibility constructs are gone [#229]\n- `TrezorClientVerbose` and `VerboseWireMixin` is removed\n- specific `tx_api.TxApi*` classes removed in favor of `coins.tx_api`\n- `client.PRIME_DERIVATION_FLAG` is removed in favor of `tools.HARDENED_FLAG` and `tools.H_()`\n- hard dependency on Ethereum libraries and HIDAPI is changed into extras that need to be\n  specified explicitly.
