Trezör® Bridge® — Connect Your Web3 World Securely™

What is Trezor Bridge?

Trezor Bridge is a communication interface that allows your Trezor hardware wallet to interact with web-based applications, including Trezor Suite. It acts as a secure middleware that facilitates data exchange between your computer’s USB-connected Trezor device and supported web browsers.

Developed and maintained by SatoshiLabs, Trezor Bridge ensures that you can access your Trezor wallet through your browser even if WebUSB is not natively supported. It replaces older communication tools like the deprecated Chrome extension and provides a streamlined, cross-platform solution.

Key Features of Trezor Bridge

Secure Communication

Bridge uses encrypted communication to transfer data securely between your Trezor device and browser-based apps.

Cross-Platform Support

Compatible with Windows, macOS, and Linux, ensuring a consistent experience across different systems.

Browser Integration

Works with Chrome, Firefox, Brave, and other browsers that do not support WebUSB natively.

Auto-Updates

Trezor Bridge updates silently in the background to ensure maximum security and compatibility.

Open Source

Completely open-source, allowing security audits and transparency in how your data is handled.

How to Install Trezor Bridge

Visit the official download page: trezor.io/bridge.
Choose the appropriate installer for your operating system (Windows, macOS, or Linux).
Run the installer and follow the on-screen instructions.
Once installed, restart your browser for the changes to take effect.
Connect your Trezor device and access Trezor Suite Web or any dApp that supports Trezor.

Trezor Bridge runs as a background service. You may notice a tray icon or see it listed in your system’s running processes.

Why Trezor Bridge Is Important

With increased browser restrictions and tighter security policies, direct USB communication between websites and hardware wallets can sometimes be limited. Trezor Bridge acts as a secure workaround that restores full functionality to browser-based Trezor operations.

It also acts as a fallback when using older operating systems or browsers that don’t support WebUSB, ensuring broader accessibility.

Security and Privacy

Trezor Bridge is built with privacy and safety in mind. It does not collect user data, track usage, or transmit private keys. All signing and sensitive operations are performed on the Trezor device itself, and any communication between the device and browser is encrypted.

✅ Open-source code audited by the community
✅ Zero telemetry or background tracking
✅ Only runs when needed
✅ Fully sandboxed and does not interact with other system components

Troubleshooting Common Issues

Trezor not detected: Ensure Trezor Bridge is running. Restart your browser after installation.
Permission issues: Try a different USB port or cable. Also, disable conflicting extensions.
WebUSB conflicts: If WebUSB is enabled, Trezor Bridge may not be needed. Try disabling it for testing.
Firewall interference: Some firewalls may block local communication. Whitelist the Bridge service if necessary.
Outdated version: Reinstall Bridge from the official site to get the latest updates.
