python-keepkey

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.

See http://www.keepkey.com for more information.

#!/usr/bin/env python

from keepkeylib.client import KeepKeyClient
from keepkeylib.transport_hid import HidTransport

def main():
    # List all connected KeepKeys on USB
    devices = HidTransport.enumerate()

    # Check whether we found any
    if len(devices) == 0:
        print('No KeepKey found')
        return

    # Use first connected device
    transport = HidTransport(devices[0])

    # Creates object for manipulating KeepKey
    client = KeepKeyClient(transport)

    # Print out KeepKey's features and settings
    print(client.features)

    # Get the first address of first BIP44 account
    # (should be the same address as shown in KeepKey wallet Chrome extension)
    bip32_path = client.expand_path("44'/0'/0'/0/0")
    address = client.get_address('Bitcoin', bip32_path)
    print('Bitcoin address:', address)

    client.close()

if __name__ == '__main__':
    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
