Trezor Bridge® is the official connection software developed by Trezor® to enable secure communication between your Trezor hardware wallet and your web browser. It plays a critical role in ensuring that your device can safely interact with Trezor web applications such as Trezor Suite and other supported services.
Trezor Bridge® is a lightweight system-level application that replaces older browser plugins previously required to connect Trezor devices. Modern browsers no longer support those plugins, which is why Trezor Bridge® exists as a secure, up-to-date solution.
Once installed, Trezor Bridge® automatically detects your connected Trezor device and allows supported websites to communicate with it safely. This ensures seamless access to features like account management, transaction signing, and firmware updates.
Security is the core philosophy behind every Trezor product. Trezor Bridge® is designed to maintain strict separation between your private keys and your computer. Even if your browser or operating system is compromised, your crypto remains protected.
Trezor Bridge® runs as a background service on your computer. When you connect your Trezor device via USB, the Bridge detects it instantly. When you visit a compatible website like Trezor Suite, the site communicates with the Bridge, which then securely relays commands to your device.
All sensitive operations—such as signing transactions—are confirmed directly on the Trezor hardware wallet screen, not on your computer.
Trezor Bridge® supports all major desktop operating systems and modern browsers. It is optimized to work smoothly with:
Some browsers support WebUSB, allowing direct communication without Bridge. However, Trezor Bridge® remains the most stable and widely compatible solution, especially for users who rely on multiple browsers or operating systems.
Many users prefer Trezor Bridge® because it works consistently in the background and avoids browser-specific limitations.
If your Trezor device is not detected, ensure that Trezor Bridge® is installed correctly and running. Try reconnecting the USB cable or restarting your browser.
Clear your browser cache, disable conflicting extensions, and confirm you are using an official Trezor-supported website.
