Examples demonstrating how to use trezorctl
|
|
===========================================
|
|
|
|
Show all available `options <OPTIONS.rst>`_:
|
|
|
|
.. code::
|

|
$ trezorctl --help
|
|
|
|
|
|
Retrieve features, settings and coin types supported by your device:
|
|
|
|
.. code::
|
|
|
|
$ trezorctl get-features
|
|
|
|
|
|
Bitcoin examples
|
|
----------------
|
|
|
|
Get first receiving address of first account for Bitcoin (Legacy / non-SegWit):
|
|
|
|
.. code::
|
|
|
|
$ trezorctl btc get-address --script-type address --address m/44h/0h/0h/0/0
|
|
|
|
Get first receiving address of first account for Bitcoin (SegWit-in-P2SH):
|
|
|
|
.. code::
|
|
|
|
$ trezorctl btc get-address --script-type p2shsegwit --address m/49h/0h/0h/0/0
|
|
|
|
Get first receiving address of first account for Bitcoin (Bech32 native SegWit P2WPKH):
|
|
|
|
.. code::
|
|
|
|
trezorctl btc get-address --script-type segwit --address m/84h/0h/0h/0/0
|
|
|
|
Get Legacy Bitcoin ``xpub`` (can be used to create a watch-only wallet):
|
|
|
|
.. code::
|
|
|
|
trezorctl btc get-public-node --address m/44h/0h/0h
|
|
|
|
|
|
Transaction signing
|
|
-------------------
|
|
|
|
``trezorctl`` supports offline signing of transactions in a `custom JSON format <transaction-format.md>`_.
|
|
If you have transaction data in file ``tx.json``, use the following call to get the signature:
|
|
|
|
.. code::
|
|
|
|
$ trezorctl btc sign-tx tx.json
|
|
Please confirm action on your Trezor device
|
|
|
|
Signed transaction:
|
|
02000000025a6bdf3ac73e3e7047380d484e2f7d58ea633a509b9a63fe95fab84d64(...)
|
|
|
|
A provided script can be used to sign transactions interactively. You will need the following pieces of info:
|
|
|
|
1) Transaction ID containing the Output we want to spend (aka ``prevhash`` or ``a5ea715a...d201e64e`` in example below).
|
|
2) Index number of the Output being spent from the above tx (aka ``previndex`` or ``0`` in example below).
|
|
3) BIP32 path to the Node which can spend the above UTXO (eg ``Bitcoin/0h/0/0`` for the first).
|
|
4) Destination address where you want to send funds (eg ``3M8XGFBKwkf7miBzpkU3x2DoWwAVrD1mhk`` below).
|
|
5) Amount to send in satoshis - ``91305`` in the example below (multiply BTC amount 0.00091305 by 100,000,000).
|
|
6) Expected fee (``0.00019695`` BTC in example below). Note: the miner receives all satoshis left unspent from a transaction. If you want to receive some change, you need to send it to an address you own (otherwise it will go to miner). Fee is not needed below, we just want it as a sanity check.
|
|
|
|
There are many ways to retrieve the info above: from a watch-only wallet in Bitcoin Core, https://coinb.in (`screenshot <sign_tx-coinb.in.png>`_) etc. The easiest way is using the Trezor Suite: https://suite.trezor.io
|
|
|
|
After authenticating, open the "Send" tab, fill-out all details, then open the "Show transaction details" menu to see the info needed above (`screenshot <sign_tx-trezor.io.png>`_). Once you have the required details, you can then perform the transaction signing using ``trezorctl`` as shown in the example below:
|
|
|
|
.. code::
|
|
|
|
$ python3 tools/build_tx.py | trezorctl btc sign-tx -
|
|
|
|
Coin name [Bitcoin]: Bitcoin
|
|
|
|
Previous output to spend (txid:vout) []: a5ea715aa99ca30516f3af6f622dfe7399d883d49ad74b1fe33fdf73d201e64e:0
|
|
BIP-32 path to derive the key: Bitcoin/0h/0/0
|
|

|
|

|
|
|
|
Previous output to spend (txid:vout) []:

|
|
Amount to spend (satoshis): 91305
|
|
|
|
Output address (for non-change output) []:
|
|
BIP-32 path (for change output) []:

Transaction version [2]:

Signed Transaction:

The signed transaction text can then be inspected in Electrum (`screenshot <sign_tx-electrum2.png>`_), `coinb.in <https://coinb.in/?verify=01000000014ee601d273df3fe31f4bd79ad483d89973fe2d626faff31605a39ca95a71eaa5000000006a47304402206386a0ad0f0b196d375a0805eee2aebe4644032c2998aaf00e43ce68a293986702202ad25964844657e10130f81201b7d87eb8047cf0c09dfdcbbe68a1a732e80ded012103b375a0dd50c8dbc4a6156a55e31274ee0537191e1bc824a09278a220fafba2dbffffffff01a96401000000000017a914d53d47ccd1579b93c284e9caf3c81f3f417871698700000000#verify>`_ or another tool. If all info is correct, you can then broadcast the tx to the Bitcoin network via the URL provided by ``trezorctl`` or Electrum (Tools → Load transaction → From text. Here is a `screenshot <sign_tx-electrum1.png>`_). TIP: Electrum will only show the transaction fee if you previously imported the spending address (eg ``16ijWp48xn8hj6deD5ZHSJcgNjtYbpiki8`` from example tx above). Also, the final tx size (and therefore satoshis / byte) might be slightly different than the estimate shown on suite.trezor.io

Litecoin examples
|
|
-----------------
|
|
|
|
Get first receiving address of first account for Litecoin (SegWit-in-P2SH):
|
|
|
|
.. code::
|
|
|
|
$ trezorctl ltc get-address --script-type p2shsegwit --address m/49h/2h/0h/0/0

|
|
|
|
.. code::
|
|
|

Notes
|
|
-----
|
|
|
|
1. Bech32 native SegWit encoded addresses require `Trezor Firmware v1.6.0 <https://github.com/trezor/trezor-mcu/releases>`_ or later.
