The Vital Link for Your Trezor Hardware Wallet
Trezor Bridge is the background application that facilitates secure communication between your Trezor device and your internet browser or the Trezor Suite app.
What is Trezor Bridge?
Understanding the core technology behind your secure transactions.
Communication Protocol
Trezor Bridge acts as a communication driver. It runs in the background of your operating system and allows your computer to recognize and interact with your Trezor hardware wallet via USB.
Replaces WebUSB
While some modern browsers support WebUSB, Trezor Bridge offers a more stable and universally compatible connection method, ensuring your device works seamlessly across different platforms and browsers.
Privacy Focused
The software is designed to be lightweight and privacy-centric. It only transmits necessary data between the device and the interface, without storing your private keys or sensitive information.
Integration with Trezor Suite App
The Trezor Suite app is the comprehensive interface for managing your crypto assets. Trezor Bridge is the invisible engine that powers this experience.
When you launch Trezor Suite, it automatically detects the running Bridge process. This handshake allows the application to display your balances, sign transactions, and manage your portfolio without ever exposing your private keys to the internet.
- Seamless device detection
- Faster transaction signing
- Enhanced stability during firmware updates
- Universal compatibility with desktop operating systems
Uncompromising Security
Security is the cornerstone of the Trezor ecosystem.
Local Execution
Trezor Bridge runs locally on your machine (localhost:21325). This local server approach ensures that communication remains within your computer's internal network environment, reducing exposure to external threats.
Verified Signatures
All official Trezor Bridge binaries are digitally signed by SatoshiLabs. This cryptographic signature guarantees the authenticity of the software, ensuring you are not running a compromised version.
Open Source
Like all Trezor software, the Bridge is open source. This transparency allows security researchers and the community to audit the code, ensuring there are no backdoors or vulnerabilities.
Installation & Updates
For most users, Trezor Bridge is installed automatically when setting up the Trezor Suite app. However, it can also be installed manually if you are using the web interface or troubleshooting connection issues.
System Requirements:
- Windows 10 or newer
- macOS 10.15 or newer
- Linux (x64, arm64)
Note: Always ensure you are running the latest version to maintain optimal compatibility with new firmware releases.
