Trezor Bridge — Secure Connection Between Wallet & Browser
Trezor Bridge is a lightweight communication tool that enables seamless interaction between your Trezor hardware wallet and supported web browsers. It plays a critical role in ensuring secure, reliable, and direct communication between your device and wallet interfaces such as Trezor Suite and other compatible third-party applications.
What Is Trezor Bridge?
Trezor Bridge is a background service installed on your computer that allows web-based applications to detect and communicate with your Trezor hardware wallet. Unlike browser extensions, Trezor Bridge operates independently of the browser, improving compatibility, stability, and security.
Once installed, Trezor Bridge runs silently in the background and automatically handles the connection whenever you access a supported wallet interface.
Why Trezor Bridge Is Important
Modern browsers have limited native support for USB hardware wallet communication. Trezor Bridge solves this limitation by acting as a secure intermediary, ensuring that sensitive operations—such as signing transactions or verifying addresses—are properly routed to your Trezor device.
Key benefits include:
- Secure device communication without exposing private keys
- Improved browser compatibility across Chrome, Firefox, Edge, and others
- Automatic detection of connected Trezor devices
- Reduced reliance on browser extensions, which can introduce vulnerabilities
How Trezor Bridge Works
When you connect your Trezor hardware wallet to your computer via USB, Trezor Bridge detects the device and establishes a secure communication channel. Wallet interfaces then send requests through Trezor Bridge, which relays them to the device for physical confirmation.
All critical actions—such as transaction approvals—must still be confirmed directly on your Trezor device, ensuring that private keys never leave the hardware wallet.
Installing Trezor Bridge
Installing Trezor Bridge is straightforward:
- Visit the official Trezor website.
- Download the correct version for your operating system (Windows, macOS, or Linux).
- Run the installer and follow the on-screen instructions.
- Restart your browser if prompted.
Once installed, no additional configuration is required. Trezor Bridge will update automatically when new versions are released.
Trezor Bridge vs. WebUSB
Some modern browsers support WebUSB, which allows direct device communication without Trezor Bridge. However, Trezor Bridge remains the most reliable option, especially for users who prefer broader browser support or use older systems.
Trezor Suite will automatically choose the best available connection method, ensuring a smooth user experience.
Final Thoughts
Trezor Bridge is an essential component of the Trezor ecosystem, enabling secure and reliable communication between your hardware wallet and web-based interfaces. By keeping your private keys offline while ensuring smooth usability, Trezor Bridge helps maintain the high security standards Trezor is known for.
