Trezor Firmware
There is no support for this in Trezor Suite, and Mojito also does not support it yet, although it is currently in development.
Support is available in wallet-cli and node-gui, but at the time of writing, these changes have not yet been released, so you will need to build the applications from the latest master branch manually.
Flashing unofficial firmware may render your Trezor device unusable until it is successfully recovered.
Proceed only if you fully understand each step and accept the associated risks. Do not attempt this on your primary or production hardware wallet unless you are absolutely certain of what you’re doing.
Building Mintlayer Trezor Firmware
Ubuntu 24.04 is the recommended environment for building the Mintlayer Trezor firmware. The following steps will guide you through the process of setting up your environment and building the firmware.
sudo apt update # Update package lists to get the latest available versions
sudo apt install git # Install Git for cloning repositories
git clone --recurse-submodules https://github.com/mintlayer/mintlayer-trezor-firmware.git # Clone the firmware repo including its submodules
cd mintlayer-trezor-firmware # Change directory to the cloned firmware project
git checkout mintlayer-master # Switch to the Mintlayer-specific firmware branch
curl -sSL https://install.python-poetry.org | python3 - # Install Poetry, a dependency manager for Python
poetry install # Install Python dependencies listed in pyproject.toml
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh # Install Rust
rustup default nightly # Set the nightly version of Rust as the default toolchain
rustup component add rust-src --toolchain nightly-x86_64-unknown-linux-gnu # Add Rust source code and the required toolchain
sudo apt install -y build-essential # Install essential tools for building software (e.g., gcc, make)
sudo apt install -y python3.12-dev libffi-dev # Install Python 3.12 development headers and foreign function interface libraries
sudo apt install -y gcc-arm-none-eabi binutils-arm-none-eabi libnewlib-arm-none-eabi # Install cross-compilation toolchain for ARM (used by Trezor)
sudo apt install -y protobuf-compiler # Install the Protocol Buffers compiler (used in serialization)
sudo apt install -y clang llvm-dev libclang-dev # Install LLVM/Clang compiler and development libraries
cd core # Move into the `core` directory of the firmware source
source $(poetry env info --path)/bin/activate # Activate the virtual environment created by Poetry
TREZOR_MODEL=T3T1 make vendor build_firmware # Set the target Trezor model and build the firmware with required vendor files
Pre-requisites
Device bootloader must be unlocked to allow unofficial firmware installation. This can be done by following the instructions in the Trezor documentation.
