Trezor Bridge is the secure communication layer that connects your Trezor hardware wallet to supported web browsers. It enables smooth and encrypted interaction between your device and online wallet interfaces while keeping your private keys protected.
Trezor Bridge is a lightweight software application developed to allow direct communication between your computer’s browser and your Trezor hardware wallet. Modern browsers have security restrictions that prevent direct USB communication. Trezor Bridge solves this issue by acting as a trusted local connector.
Once installed, the software runs quietly in the background. It does not require regular interaction and automatically activates whenever a supported web application needs access to your Trezor device.
Without Trezor Bridge, your browser may not detect your hardware wallet properly. This communication tool ensures reliable and encrypted data exchange while maintaining Trezor’s strict security model.
Establishes an encrypted local connection between your browser and your Trezor device.
Compatible with Windows, macOS, and Linux systems for broad accessibility.
Private keys remain safely stored on your hardware wallet at all times.
Runs silently after installation and activates only when needed.
When you connect your Trezor hardware wallet via USB, Trezor Bridge detects the device and creates a secure communication channel. The browser interface communicates with Trezor Bridge locally, while all cryptographic operations and transaction signing remain inside the hardware wallet itself.
The installation is quick and straightforward. After setup, the software requires no additional configuration in most cases.
Trezor Bridge is primarily required when using browser-based wallet interfaces or third-party web integrations. If you are using the desktop version of Trezor Suite, Bridge may not be necessary because the desktop app communicates directly with the device.
Most connectivity issues can be resolved quickly by reinstalling or restarting the software.
