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 wallet.trezor.io)
bip32_path = client.expand_path("44'/0'/0'/0/0")
address = client.get_address('Bitcoin', bip32_path)
print('Bitcoin address:', address)
client.close()
