Trezor® Bridge: Secure Connection for Your Hardware Wallet®
Trezor Bridge is the lightweight desktop bridge application that enables secure and reliable communication between your Trezor hardware wallet and web-based wallet interfaces. It acts as a trusted intermediary so your private keys remain isolated on your device while allowing transaction signing and device management.
What is Trezor Bridge?
Trezor Bridge is a small, local application that runs on your computer and provides a stable communication channel between your browser and the Trezor device. Unlike browser extensions or direct USB access that can be blocked by browser updates or security policies, Bridge gives a consistent way to access your hardware wallet across operating systems.
Key Security Benefits
- Isolated private keys: All sensitive signing operations happen on the Trezor device itself. Bridge only facilitates message passing.
- Local-only communication: Bridge runs locally and does not forward private information to external servers.
- Integrity checks: The Bridge binary is signed and distributed through official channels so you can verify authenticity before installation.
How to Install and Use
Download the official Bridge installer from the Trezor website, choose the installer appropriate for your operating system (Windows, macOS, Linux) and follow the setup prompts. After installation, Bridge runs in the background and will appear when you connect your Trezor device. Open your preferred wallet interface, connect the device, and confirm actions on the Trezor screen.
Troubleshooting Tips
If your browser cannot detect the device, first ensure Bridge is running. Restarting the Bridge service, reconnecting the cable, or trying a different USB port often resolves most connection issues. Keep your device firmware and Bridge installation up to date for best compatibility.
Common fixes
- Restart your computer and reconnect the Trezor.
- Check that no other wallet tools are conflicting with Bridge.
- Reinstall Bridge from the official source if problems persist.
Best Practices
Always download Bridge from official sources; never install packages from untrusted websites. Use a hardware-confirmed PIN and backup seed, validate all transaction details on the device display before approving, and keep your recovery seed offline and secure.
