About the Trézor Bridge
The Trézor Bridge is a background communication tool that connects your Trezor hardware wallet to supported interfaces like the Trezor Suite App. It acts as the essential “bridge” enabling your browser or app to talk to the device safely and locally.
When you plug in your Trezor device, the Bridge runs quietly on your computer to manage data exchange. This ensures that no sensitive information — like private keys or recovery seeds — ever leave your physical hardware wallet. By using local communication instead of web-based APIs, Trezor eliminates most remote attack surfaces.
Users are prompted to install the Bridge when first connecting their device via Trezor.io/start. Once installed, the Bridge launches automatically on system startup. You can connect multiple Trezor devices simultaneously, and each session remains isolated for maximum safety.
One major advantage of the Trézor Bridge is its resilience against phishing or injection attacks. The software creates a secure pipe between your device and trusted Trezor software only. Any unauthorized applications attempting access are rejected by design.
The Bridge supports all operating systems — Windows, macOS, and Linux — and receives continuous updates. The Trezor team maintains open-source transparency, allowing independent researchers to review the Bridge’s code and security practices.
For power users, Trezor Bridge integrates smoothly with advanced tools like Electrum or third-party wallet managers. It enables these applications to access Trezor’s secure signing features while keeping your private data protected by the device’s firmware.
Installing the Bridge is simple: download from the official Trezor.io/start page, run the installer, and restart your browser or Suite app. Once active, your system will automatically detect any connected Trezor wallet. You’ll notice the LED or device screen confirming communication with your desktop app.
Beyond security, the Trezor Bridge ensures consistent user experience. Data synchronization, firmware updates, and Suite connectivity all rely on its reliable background service. If you disable it, your Trezor may not appear in supported applications.
In summary, the Trézor Bridge forms the backbone of safe hardware wallet communication. It is light, fast, and open-source — blending usability and security into one seamless system that respects your digital sovereignty.
