Project description

https://travis-ci.org/trezor/python-trezor.svg?branch=master https://badges.gitter.im/trezor/community.svg

Client side implementation for TREZOR-compatible Bitcoin hardware wallets.

See http://bitcointrezor.com for more information.

Example

also found in helloworld.py

#!/usr/bin/env python

from trezorlib.client import TrezorClient
from trezorlib.transport_hid import HidTransport

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

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

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

    # Creates object for manipulating TREZOR
    client = TrezorClient(transport)

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

    # Get the first address of first BIP44 account
    # (should be the same address as shown in mytrezor.com)
    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 TREZOR display and enter the their positions using the numeric keyboard mapping:

7 8 9
