Trezor hardware wallet support

This module adds Trezor hardware support to Monero.

Basic information

Trezor integration is based on the following original proposal: https://github.com/ph4r05/monero-trezor-doc

A custom high-level transaction signing protocol uses Trezor in a similar way a cold wallet is used. Transaction is build incrementally on the device.

Trezor implements the signing protocol in trezor-firmware repository, in the monero application. Please, refer to monero readme for more information.

Dependencies

Trezor uses Protobuf library. Monero is now compiled with C++ 17 by default. Protobuf v21 is tested, older versions are not guaranteed to work. Note that Protobuf v23+ requires C++ 17.

If you are getting Trezor compilation errors, it may be caused by abseil (protobuf dependency) not being compiled with C++17. To fix this try installing protobuf from sources:

git clone --recursive git@github.com:protocolbuffers/protobuf.git
cd protobuf
cmake -DABSL_PROPAGATE_CXX_STD=TRUE -DCMAKE_CXX_STANDARD=17 -Dprotobuf_BUILD_SHARED_LIBS=ON -Dprotobuf_BUILD_TESTS=OFF .
cmake --build .
sudo make install

If Monero is compiled with C++14, Protobuf v21 is the latest compatible protobuf version for C++ 14. If you want to compile Monero with Trezor support with C++14, please make sure the Protobuf v21 is installed.

More about this limitation: PR #8752, 1, 2

OSX

To build with installed, but not linked Protobuf v21:

CMAKE_PREFIX_PATH=$(find /opt/homebrew/Cellar/protobuf@21 -maxdepth 1 -type d -name "21.*" -print -quit) \
make release

or to install and link as a default protobuf version:

# Either install all requirements as
brew update && brew bundle --file=contrib/brew/Brewfile

# or install protobufv21 specifically
brew install protobuf@21 && brew link protobuf@21

Other systems

  • install Protobuf v21
  • point CMAKE_PREFIX_PATH environment variable to Protobuf v21 installation.

Troubleshooting

To disable Trezor support, set USE_DEVICE_TREZOR=OFF, e.g.:

USE_DEVICE_TREZOR=OFF make release
