Trezor Bridge is an essential system component that enables secure communication between your Trezor hardware wallet and web browsers. It allows browser-based wallets and services to interact safely with your Trezor device without exposing private keys.
Trezor Bridge is a lightweight background application developed by Trezor. Its primary purpose is to connect your Trezor hardware wallet to web-based interfaces, such as Trezor Suite (web version) and supported third-party wallets.
Modern browsers restrict direct USB access for security reasons. Trezor Bridge solves this by acting as a secure intermediary, ensuring that communication between the browser and the hardware wallet is encrypted, authenticated, and protected.
Without Trezor Bridge, web applications would be unable to detect or communicate with your Trezor device. The Bridge ensures compatibility across browsers while maintaining strict security boundaries.
It is especially important for users who prefer browser-based crypto management instead of desktop-only applications.
Once installed, Trezor Bridge runs as a background service on your computer. When a supported website requests access to your Trezor device, the Bridge verifies the request and establishes a secure connection.
All sensitive operations, such as signing transactions or confirming addresses, still require physical confirmation on the Trezor device itself.
Trezor Bridge is available for major operating systems, including:
The correct version is automatically recommended during installation from official Trezor sources.
Trezor Bridge is primarily intended for browser-based usage. If you use the desktop version of Trezor Suite, the Bridge is not required because desktop apps can communicate directly with the hardware wallet.
Users who rely on web wallets or browser integrations will benefit most from installing Trezor Bridge.
Installing Trezor Bridge is straightforward. Users are guided through the process during wallet setup or when accessing web-based Trezor services.
After installation, the Bridge runs automatically in the background. No manual configuration is typically required.
Trezor Bridge is commonly used when accessing Trezor Suite via a web browser or when connecting the Trezor hardware wallet to third-party services such as DeFi platforms and Web3 applications.
If a browser does not recognize your Trezor device, ensure that Trezor Bridge is installed and running. Restarting the service or reconnecting the USB cable often resolves minor issues.
Keeping both the Bridge and device firmware up to date ensures optimal compatibility.
Trezor Bridge plays a crucial role in enabling secure browser-based interaction with Trezor hardware wallets. By acting as a trusted communication layer, it preserves the core security principles of self-custody while offering flexibility and convenience.
For users who rely on web access to manage their crypto assets, Trezor Bridge is an essential and reliable component of the Trezor ecosystem.
