Trezor Bridge — The Secure Gateway to Your Hardware Wallet®

What is Trezor Bridge?

Trezor Bridge is the communication layer — a small, trusted application that allows your web browser or desktop Trezor Suite to talk to a Trezor hardware wallet. It acts as a secure gateway, translating requests between the Suite app and the device while ensuring transport-level safety. This guide covers installation, security considerations, troubleshooting, and recommended practices for safe use.

Core benefits of the Bridge

Secure transport

Bridge isolates the USB connection and ensures that signed commands go to the device, protecting private keys on the device.

Compatibility

Works with the Trezor Suite desktop and web interfaces across Windows, macOS and Linux.

Simple updates

Bridge can be updated safely through verified releases to maintain compatibility and security.

Trusted integration

Bridge keeps the private-key operations on-device while enabling user-friendly management in the Suite.

Install Trezor Bridge — step-by-step

Download from an official source

Only download Bridge from an official page. Always verify the URL and digital signatures if provided to avoid tampered installers.

Run the installer

Follow platform-specific prompts. On macOS you may need to allow permissions in Security & Privacy; on Windows accept the installer UAC prompt.

Restart browser or Suite

After install, restart your browser or the Trezor Suite app so the new Bridge service is detected and requests can be routed to your device.

Connect and verify

Plug in your Trezor device, open Suite, and confirm the connection. Verify device prompts on the hardware screen before approving any action.

Troubleshooting Bridge

If your browser or Suite does not detect the device: check cables, try different USB ports, reinstall Bridge, restart your computer, and ensure no other apps are blocking USB access. On Linux ensure udev rules are installed (if required). If conflicts persist, consult official support channels and avoid third-party downloads.

Security best practices

Download Bridge only from verified pages and check release notes.
Do not enter your recovery seed into any computer — seeds belong offline only.
Verify firmware updates and update Bridge only when necessary and from official sources.
Confirm addresses and transaction details on the device screen before approving — never rely only on the computer display.

Important: Bridge is a facilitator — the private keys never leave your hardware wallet. Keep your seed offline and protect it as the ultimate recovery method.

Common questions

Does Bridge store private keys? No — Bridge only handles communication. Private keys remain secured inside the hardware device and never get transmitted to the host.

Is Bridge required? Bridge or a compatible communication method is required for web-based or Suite-based interactions with a hardware wallet on most operating systems.
