Quick explanation, how it works, install tips and basic troubleshooting.
Trezor Bridge is a small companion application that lets your web browser communicate with a Trezor hardware wallet. It acts as a bridge between the USB-connected device and browser-based wallet interfaces, enabling secure signing of transactions and safe management of private keys.
When you connect a Trezor device to your computer, the browser cannot directly access the hardware because of security restrictions. Trezor Bridge runs on your computer and exposes a local endpoint that authorized web pages can use to reach the device. The Bridge forwards messages between the web app and the Trezor device so actions like viewing addresses or signing transactions are possible.
Installing Trezor Bridge is simple: download the installer from the official Trezor website and run it for your operating system (Windows, macOS, or Linux). After installation, connect your Trezor and open your chosen wallet interface (for example, the official web wallet). The site should detect the Bridge and prompt you to connect the device.
Example: install → connect device → open wallet → allow access
Trezor Bridge only provides a local connection between your browser and device. It does not store your private keys or send them anywhere. Always download Bridge from official sources, verify links, and keep your device firmware up to date to maintain security.
If your browser won't detect the Trezor: check that Bridge is running, try reconnecting the USB cable, use a different USB port, or restart your browser. On macOS, you may need to allow the Bridge in system security settings after the first installation. Reinstalling Bridge or updating firmware often resolves persistent problems.
Keep your recovery seed secure, never share it online, and only confirm transactions you understand. Trezor Bridge is a convenient tool that enables secure interactions between hardware and web wallets — treat the device and the software as parts of a single security workflow.
