What is Trezor Bridge?
Trezor Bridge is a lightweight background service that enables secure communication between your Trezor hardware wallet and your web browser. It acts as a facilitator that allows the Trezor Wallet interface and other compatible web applications to interact with your device without requiring any browser extensions.
This essential component ensures that your private keys never leave your Trezor device while still providing a seamless user experience for managing your cryptocurrencies through web-based interfaces.
Key Features
Enhanced Security
Trezor Bridge maintains the highest security standards by ensuring that sensitive operations and private keys remain securely stored on your hardware wallet, never exposed to your computer or the internet.
Seamless Integration
The bridge works silently in the background, automatically connecting your Trezor device to supported web applications without requiring manual configuration or browser extensions.
Cross-Platform Compatibility
Available for Windows, macOS, and Linux, Trezor Bridge ensures that your hardware wallet works flawlessly regardless of your operating system or browser choice.
Automatic Updates
Trezor Bridge automatically checks for and installs updates, ensuring you always have the latest security enhancements and compatibility improvements.
How It Works
When you connect your Trezor device to your computer, Trezor Bridge establishes a secure communication channel between the device and web applications. It translates the USB communication from your hardware wallet into a format that web applications can understand through a local web server.
This architecture maintains the security model of Trezor devices by ensuring that all cryptographic operations happen on the device itself, while still providing a user-friendly interface through your browser.
Local Communication
Trezor Bridge runs a local web server that only accepts connections from your browser, preventing external access to your device.
Protocol Translation
It translates between USB HID protocol used by Trezor devices and HTTP/WebSocket protocols used by web applications.
Permission Handling
The bridge manages permissions and ensures only authorized applications can communicate with your device.
Compatibility
Trezor Bridge is designed to work with all Trezor hardware wallet models, including Trezor One and Trezor Model T. It supports all major web browsers including Chrome, Firefox, Edge, and Brave.
The service is compatible with the official Trezor Wallet web interface as well as numerous third-party applications that support Trezor integration, providing a unified experience across different platforms and services.
