Client side implementation for KeepKey-compatible Bitcoin hardware wallets.
This is a modified version of python-trezor. The changes made were to support KeepKey's protocol, as well as the additional feature set of KeepKey. For example, by default, device_recovery command invokes KeepKey's style of device recovery using the Recovery Cipher.

main()When you are asked for PIN, you have to enter scrambled PIN. Follow the numbers shown on KeepKey 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 KeepKey is displaying the following:
| 2 | 8 | 3 |

To run unit tests that don't require a device:
$ python tests/unit/*.py- Check that the testsuite runs cleanly
- Bump the version in setup.py
- Tag the release
- Build the release * sudo python3 setup.py sdist bdist_wheel bdist_egg
- Upload the release * sudo python3 -m twine upload dist/* -s --sign-with gpg2
The KeepKey Bridge is a standalone TCP-to-webusb bridge the KeepKey. It runs a python-keepkey client based process that allows a localhost-based process to communicate with the KeepKey wallet, thus bypassing the need for a webusb connection from a browser based platform.
The KeepKey Bridge is recommended only for advanced users who have problems connecting the KeepKey on Windows.
Download the KeepKey Bridge installer kkbsetup.exe for Windows in the release package here:
https://github.com/keepkey/python-keepkey/releases
When running the KeepKey Bridge, a blank cmd window with the title "KepKey Bridge" will be visible. To stop the bridge, simply close the cmd window.
Requirements:
- Windows 10
- python3
- waitress (python package)
- py2exe
- Inno Setup Compiler (optional, for creating Windows install exe)
- From a command prompt terminal window, run
python wbsetup.py py2exe -d windows/dist
This will create a windows\dist folder with the Windows stand-alone executable file wait-serv.exe
This tool builds and packages the executable for install on Windows. Build with the provided installer script (modify version, etc., as needed)
windows/KeepKeyBridge.iss
This will produce an executable install app
windows/Output/kkbsetup.exe
