Trézór Bridge®™ | Secure Crypto Connectivity
What Is Trezor Bridge?
Trezor Bridge is a small background application developed by SatoshiLabs that enables seamless communication between your Trezor hardware wallet and your web browser. It acts as a secure connector, allowing your computer and the Trezor device to exchange data safely when you access Trezor services such as Trezor Suite (web version) or other supported third-party wallets.
Unlike browser extensions, Trezor Bridge runs quietly in the background once installed, ensuring a stable and reliable connection without requiring repeated permissions.
Why Trezor Bridge Is Important
Modern web browsers limit direct access to USB devices for security reasons. Trezor Bridge solves this limitation by serving as a trusted intermediary. When you connect your Trezor wallet to your computer, the Bridge recognizes the device and enables supported web apps to interact with it securely.
This setup enhances both usability and security, ensuring that sensitive operations—such as confirming transactions or managing private keys—are performed only on the hardware wallet itself.
How Trezor Bridge Works
Once installed, Trezor Bridge automatically detects your connected Trezor device. When you open a compatible web interface, such as the Trezor Suite web app, the browser communicates with Trezor Bridge, which then relays instructions to the hardware wallet.
The Bridge does not store private keys or recovery seeds. All cryptographic operations remain isolated within the Trezor device, keeping your digital assets protected from malware or unauthorized access.
Trezor Bridge vs Browser Extensions
In earlier years, Trezor relied on browser extensions. However, extensions became less reliable due to changing browser policies. Trezor Bridge replaces these extensions with a more stable, cross-browser solution that works consistently on Windows, macOS, and Linux.
For users who prefer a desktop experience, the Trezor Suite desktop app does not require Trezor Bridge, as it communicates directly with the device.
How to Install Trezor Bridge
You can download Trezor Bridge from the official Trezor website. After installation, simply connect your Trezor wallet via USB. The Bridge starts automatically and runs in the background, requiring no further setup or configuration.
