This module adds Trezor hardware support to Monero.
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.
Trezor uses Protobuf library. As Monero is compiled with C++14, the newest Protobuf library version cannot be compiled because it requires C++17 (through its dependency Abseil library). This can result in a compilation failure.
Protobuf v21 is the latest compatible protobuf version.
If you want to compile Monero with Trezor support, please make sure the Protobuf v21 is installed.
More about this limitation: PR #8752, 1, 2
To build with installed, but not linked protobuf:
CMAKE_PREFIX_PATH=$(find /opt/homebrew/Cellar/protobuf@21 -maxdepth 1 -type d -name "21.*" -print -quit) \
make releaseor 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@21curl -O https://repo.msys2.org/mingw/mingw64/mingw-w64-x86_64-protobuf-c-1.4.1-1-any.pkg.tar.zst
curl -O https://repo.msys2.org/mingw/mingw64/mingw-w64-x86_64-protobuf-21.9-1-any.pkg.tar.zst
