Official Trézor Bridge® | Introducing the New Trezor®

As hardware wallets continue to set the standard for cryptocurrency security, supporting tools like Trezor Bridge play an important behind-the-scenes role. Trezor Bridge ensures reliable communication between your Trezor hardware wallet and browser-based crypto applications while maintaining strict security controls.

What Is Trezor Bridge?

Trezor Bridge is a lightweight software service developed by Trezor that allows web browsers to communicate with Trezor hardware wallets. Because browsers cannot directly access USB devices due to security restrictions, Trezor Bridge acts as an intermediary, enabling secure data exchange between the device and supported websites.

It runs quietly in the background and requires minimal user interaction once installed.

Why Trezor Bridge Is Still Relevant

Although Trezor Suite (desktop) now supports native device communication, Trezor Bridge remains essential for:

  • Browser-based wallet access
  • Legacy web interfaces
  • Third-party crypto services
  • Browsers without full WebUSB support

For users who prefer web wallets or rely on specific online platforms, Trezor Bridge ensures uninterrupted access.

How Trezor Bridge Works

When a user connects their Trezor wallet and visits a compatible website, the site sends a request through Trezor Bridge. The bridge forwards this request to the hardware wallet, where sensitive actions—such as signing transactions—are confirmed directly on the device screen.

At no point does Trezor Bridge store:

  • Private keys
  • Recovery seeds
  • Account credentials

All cryptographic operations remain safely within the hardware wallet.

Installation and System Compatibility

Trezor Bridge is compatible with major operating systems, including:

  • Windows
  • macOS
  • Linux

Installation typically takes only a few minutes. Once installed, the service launches automatically when the system starts. Users may need to restart their browser or computer to complete setup.

Security Features and Trust Model

Trezor Bridge follows a security-first design:

  • Open-source code for transparency
  • Encrypted local communication
  • No internet-based data storage
  • Mandatory on-device transaction confirmation

Users should always download Trezor Bridge from official Trezor sources to avoid malicious replicas.

Common Issues and Solutions

If your Trezor device is not detected:

  • Ensure Trezor Bridge is running
  • Update to the latest version
  • Disconnect conflicting wallet extensions
  • Try a different USB cable or port
  • Restart your system

Most connectivity issues are resolved through updates or simple restarts.

Best Practices for Using Trezor Bridge

  • Keep Bridge and firmware updated
  • Avoid unofficial browser plugins
  • Verify all transactions on the device screen
  • Never enter your recovery seed online
  • Use Trezor Suite when possible for enhanced stability

Conclusion

Trezor Bridge remains a reliable and secure solution for browser-based interaction with Trezor hardware wallets. While newer tools have reduced dependency on it, Trezor Bridge continues to support flexibility without compromising security. Understanding its role helps users maintain seamless and safe access to their digital assets.
