Trezor Bridge® — Browser-to-Device Connector

Q: What is Trezor Bridge?

Trezor Bridge is a browser-to-device connector that enables communication between your Trezor hardware wallet and web-based wallet interfaces.

What is Trezor Bridge and why it matters

Trezor Bridge is the essential browser-to-device connector for Trezor hardware wallets. It creates a secure channel between your browser and your Trezor device so you can manage crypto via web interfaces. The browser-to-device connector relays requests while keeping private keys on the hardware device.

Download & install: browser-to-device connector steps

Always download Trezor Bridge from the official Trezor website. The connector supports Windows, macOS and Linux. Follow these steps:

Windows: Download the .exe, run as administrator, and follow prompts.
macOS: Open the .dmg, drag to Applications, run and allow the system extension if prompted.
Linux: Use the package for your distribution or official instructions for the browser-to-device connector.

Using Trezor Bridge with browsers

Trezor Bridge works with major browsers (Chrome, Edge, Firefox with WebUSB) to allow web-based wallets to see your device. If not detected, make sure the connector is running and browser USB permissions are granted. Installing Bridge usually enables the browser-to-device connector automatically.

Security best practices

Security when using Trezor Bridge is essential. Download only from official domains, keep firmware current, never enter your recovery seed on a computer, and always confirm transactions on the device screen. The browser-to-device connector relays messages but the device signs transactions.

Troubleshooting common issues

Fix connector problems by restarting the Bridge service or reinstalling. Try different USB ports or cables, update your browser, disable interfering antivirus temporarily, and check firmware. These steps resolve most browser-to-device connector issues.
