Trezor-firmware is the official repository for the firmware of Trezor hardware wallets, developed by SatoshiLabs. It contains the source code for both Trezor One and Trezor Model T devices, as well as the associated tools and libraries for development and testing.

Pros

• Open-source, allowing for community audits and contributions
• Supports multiple cryptocurrencies and tokens
• Regular updates and security improvements
• Extensive documentation and developer resources

Cons

• Complexity may be challenging for new contributors
• Limited to Trezor hardware devices
• Requires specialized knowledge in embedded systems and cryptography
• Potential for security vulnerabilities if not properly maintained

Code Examples

This is not a code library in the traditional sense, but rather a firmware project. However, here are a few examples of how developers might interact with the project:

1. Building the firmware:

# Clone the repository
git clone https://github.com/trezor/trezor-firmware.git
cd trezor-firmware

# Install dependencies
pip3 install -r requirements.txt

# Build firmware for Trezor Model T
make -C core

2. Running tests:

# Run unit tests for core
pytest tests/device_tests

3. Flashing firmware to a device:

# Flash firmware to Trezor Model T
python3 -m trezorctl firmware-update -f build/core/firmware.bin

Getting Started
