Trezor Bridge: Secure Connection Between Your Wallet and Browser
Trezor Bridge is a lightweight communication tool that enables your Trezor® hardware wallet to securely connect with web-based applications and supported browsers. It acts as a trusted bridge between your device and online interfaces, ensuring that sensitive operations are handled safely without exposing your private keys.
What Is Trezor Bridge?
Trezor Bridge allows browsers to detect and communicate with your Trezor hardware wallet. It replaces older browser extensions and provides a more stable, secure way for web applications—such as Trezor Suite Web or third-party crypto services—to interact with your device.
Private keys never leave your Trezor device. Trezor Bridge only facilitates communication, while all cryptographic signing and approvals occur directly on the hardware wallet.
Why Trezor Bridge Is Important
Modern browsers limit direct access to USB devices for security reasons. Trezor Bridge solves this by acting as an intermediary, allowing safe USB communication while maintaining strict security standards.
Key benefits include:
Secure USB Communication: Enables reliable device detection
Improved Browser Compatibility: Works with major browsers and operating systems
No Key Exposure: Private keys remain offline at all times
Automatic Updates: Ensures ongoing compatibility and security
When Do You Need Trezor Bridge?
You typically need Trezor Bridge when:
Using Trezor Suite Web instead of the desktop app
Accessing third-party web wallets or DeFi platforms that support Trezor
Your browser does not natively support WebUSB
If you are using Trezor Suite Desktop, Trezor Bridge is usually not required, as the desktop application communicates directly with the device.
Supported Platforms
Trezor Bridge is compatible with:
Windows
macOS
Linux
It runs silently in the background and does not interfere with other applications.
Security Best Practices
Download Trezor Bridge only from official Trezor sources
Keep your browser and operating system up to date
Never approve transactions you don’t recognize on your device screen
Ignore any website asking for your recovery seed
Trezor will never request your recovery phrase online.
Common Issues and Troubleshooting
If your browser does not recognize your Trezor device:
Ensure Trezor Bridge is installed and running
Try reconnecting the USB cable
Restart your browser or computer
Use a supported browser
Most connectivity issues are resolved by installing or updating Trezor Bridge.
Final Thoughts
Trezor Bridge plays a crucial role in enabling secure, browser-based interactions with your Trezor hardware wallet. By providing a trusted communication layer, it allows users to access web applications confidently while maintaining the highest level of security.
