Trezor Bridge is the lightweight service that lets desktop apps and browsers talk to your Trezor hardware wallet securely. Plug in, approve on-device, and transact with robotic precision.
Available for Windows, macOS, and Linux • Secure, minimal, and privacy-respecting
From download to first confirmation — usually under two minutes.
Choose your OS and grab the latest installer from the official source.
Launch the installer and follow the guided setup. No complex options required.
Plug in your device via USB. Your OS detects Bridge and pairs securely.
Confirm requests on your Trezor screen. Keys never leave the device.
Bridge relays requests without exposing private keys, keeping all approvals on the hardware wallet.

Minimal background footprint with automatic start and silent updates when available.
Hardened local communication channel with retries, timeouts, and integrity checks.
Handles multiple Trezor devices gracefully and prompts you to pick the active one.

Installer with service manager. Requires admin to install.
Notarized package. First launch may ask to allow extensions.
Includes udev rules. May require re-plugging the device after install.
Bridge spins up a local service listening on a safe loopback interface.
Client apps send signed requests; Bridge forwards them to your Trezor.
You review the operation on the device screen and confirm physically.
Bridge returns the result to the app — without exposing private keys.
Try another USB port/cable, re-plug after install, and ensure no other wallet apps are using the device.
Enable browser support in the app, close conflicting tabs, or use Trezor Suite Desktop for the most reliable pairing.
On macOS/Linux, grant USB permissions or apply udev rules. Restart Bridge service afterwards.
Bridge is recommended for desktop apps and some browsers to ensure stable communication. Trezor Suite Desktop can communicate directly, but Bridge improves compatibility across tools.
