Proof of concept demo

PoC demonstrates spending implemented via signing protocol as described in the docs. There are the following components:

  • Trezor server, representing connected Trezor device. Isolated process, communicates over API.
  • Trezor agent, host-based utility implementing host side of the signing protocol.
  • Agent spawns custom monero-wallet-rpc

Should you need any more unmerged features here is my fork:

https://github.com/ph4r05/monero/tree/ph4master

Usage

  • Generate wallet credentials on the first Trezor server start.
  • Start agent, fetch watch-only credentials from Trezor.

Spending is then following:

  • Generate unsigned transaction with agent
  • Trezor agent (watch-only credentials) signs the transaction with Trezor server
  • Submit signed transaction with the agent to the

Submitting signed transaction

Key image sync feature is not yet implemented.

Python 3 is supported only (asyncio).

Creating wallet

# Clone project
$> git clone https://github.com/ph4r05/monero-agent.git
$> cd monero-agent

# Install poc dependencies
$> pip install .[poc]

Start Trezor server

For PoC there is standalone running Trezor HTTP server emulating Trezor device. It contains full wallet credentials and communicates over HTTP according to the signing protocol described in the docs.

$> python3 -m monero_poc.trezor --account-file ./trezor.json --testnet --debug

Account file argument points to a file where the Trezor server stores all its information for consecutive executions. It is created on the wallet initialization.

To use the PoC the wallet has to be generated. Call command new_wallet. It generates you a new Monero wallet in the Trezor server.

Wallet generated
[trezor 9vAJfX]:

Trezor wallet is now initialized and ready to use.

Agent

In order to work with PoC running Agent is required.

The Agent spawns custom monero-wallet-rpc and keeps it running in the background. Agent terminates monero-wallet-rpc on exit.

During the first start Agent loads watch-only credentials from the connected Trezor:

$> python3 -m monero_poc.agent --account-file agent.json \
    --watch-wallet /tmp/savvv \
    --monero-bin ~/workspace/monero/build/debug/bin/  \
    --rpc-addr 127.0.0.1:4808
Loading watch-only credentials from Trezor. Please, confirm the request on Trezor.
  • --account-file represents state file for the Agent. It stores the state for the consecutive executions. The file is created on the first start.
  • --watch-wallet is the path to monero watch-only wallet that will be created by Agent. This key file can be loaded by monero-wallet-cli and is used by monero-wallet-rpc spawned by agent
  • --rpc-addr 127.0.0.1:4808 enables to set address of monero full node.

Agent now tries to fetch watch-only credentials from the Trezor. Confirm the action on the Trezor:

Security Note

Trezor configuration files are not protected / encrypted on purpose in the PoC. The idea is to give freedom to work with JSON files (e.g, change to another address) if needed.

Note: For the PoC sake some communication between Trezor and Agent is serialized with pickle. This is not secure as pickle is not immune to malformed / tampered archives. In the production a protobuf messages will be constructed and use which are safe w.r.t. tampering.

Transaction signing and key image sync protocol are already transformed to the protocol message form.

This is the old way of spending using monero-wallet-cli. The monero wallet key file generated by agent can be opened by monero-wallet-cli so user can perform additional tasks not yet implemented in the Agent.

Submit transfer

Use watch only hot wallet to submit signed transaction. This step performs also key image synchronisation so hot wallet is able to construct new transactions, otherwise it could construct invalid transactions without knowing which UTXOs have been spent which leads to double spending error.

Place signed_monero_tx file produced by the Agent to the running directory of the wallet.

Seed utility

There is a small utility provided for converting mnemonics to Monero wallets.

It generates Monero private/public keys, addresses and sub-addresses from the input which can be:

  • BIP44 mnemonics as used with Trezor
  • BIP44 master seed derived from mnemonics
  • Monero electrum mnemonics
  • Monero master seed

Example:

$> python -m monero_poc.seed --electrum-mnemonics --subs --testnet obedient coexist syringe lamb tacit hover hold subtly industrial puppy superior object push lakes geek welders oust colony rapid ointment thorn spiders mechanic nobody ointment
Seed Monero:      283d8bab1aeaee8f8b5aed982fc894c67d3e03db9006e488321c053f5183310d
Seed Monero wrds: obedient coexist syringe lamb tacit hover hold subtly industrial puppy superior object push lakes geek welders oust colony rapid ointment thorn spiders mechanic nobody ointment

Trezor seeds

The seed utility can help with generation of the Monero-related secrets from the master Trezor seed.

Warning: you should never execute these scripts with your real seeds in an insecure environment, which is basically every workstation. Entering seeds to electronic devices should be only the last recovery option, performed on a freshly booted, security-oriented system, such as Tails or Whonix.

Install dependencies

$> pip install .[poc,trezor]

Testing with Trezor

Agent supports also communication with Trezor directly. It works in the same way as described above. If the account file does not exist on the agent start it will prompt Trezor for watch-only credentials.

Agent requires python-trezor which facilitates communication with the Trezor over Trezor protocol.

$> pip install .[trezor]

The following command for communication with the Trezor Emulator running on port 21324.

python -m monero_poc.agent --debug --account-file agent25.json --watch-wallet wallet25 \
    --monero-bin ~/workspace/monero/build/debug/bin/ \
    --rpc-addr 127.0.0.1:28081 \
    --testnet \
    --trezor --trezor-path udp:127.0.0.1:21324

Or to communicate directly with the Trezor device connected to the USB:

python -m monero_poc.agent --debug --account-file agent25.json --watch-wallet wallet25 \
    --monero-bin ~/workspace/monero/build/debug/bin/ \
    --rpc-addr 127.0.0.1:28081 \
    --testnet \
    --trezor --trezor-path bridge:web01

Testing

For testing I recommend setting PYOPT variable to 0 in SConstript.firmware file which enables debug mode on the Trezor (both emulator and hardware device).

With the debug mode you are allowed to initialize the device with seed you want so you can run tests with the device.

Also you should get an access to the serial console for the hardware device to see logging output:

# Minicom serial console:
$> minicom -b 115200 -D /dev/tty.usbmodem1413

# Screen also works, set 3000 lines limit
$> screen -h 3000 /dev/tty.usbmodem1413 115200

# My utility, simple scrolling, augmenting log output with time
$> python -m monero_poc.log_aux --serial /dev/tty.usbmodem1413

Testing in emulator

make build_unix
PYOPT=0 make emu

Testing with the device

To upload a new firmware image you need to switch Trezor to the bootloader mode. This is done by constantly moving finger across device display while connecting device to the USB (on device powerup). In case of success the white screen appears, asking whether to connect to the host.

PATH=/absolute_path_to_toolchain/gcc-arm/gcc-arm-none-eabi-5_4-2016q3/bin/:$PATH PYOPT=1 make build_firmware
PATH=/absolute_path_to_toolchain/gcc-arm/gcc-arm-none-eabi-5_4-2016q3/bin/:$PATH PYOPT=1 make upload

Running tests

There are tests implemented to test trezor-core monero implementation. To run these tests call

EC_BACKEND_FORCE=1 EC_BACKEND=1 python -m unittest trezor_monero_test/test_trezor.py

The environment variables will force monero agent to use py-trezor-crypto library which is fast and secure. Tests read TREZOR_PATH environment variable which defaults to udp:127.0.0.1:21324.

Currently there are 16 different transaction scenarios implemented and one key image sync.

Changes on trezor-common updates

Once trezor-common is updated, e.g., new message type is added the following steps are needed to do:

trezor-core

# 1. Update vendor trezor-common submodule in trezor-core

# 2. Regenerate messages
cd tools
./build_protobuf
./build_templates

python-trezor

# 1. Update vendor trezor-common submodule in python-trezor

# 2. Rebuild protobuf messages
python setup.py develop

# 3. Update python-trezor in monero-agent directory (or system wise)
pip install -U --no-cache ../python-trezor/

agent

# 1. Update vendor trezor-common submodule in monero-agent

# 2. Rebuild protobuf messages
python setup.py develop
