Trezor Bridge is a dedicated communication tool developed by SatoshiLabs that enables web browsers to securely interact with Trezor® hardware wallets. It acts as a liaison between your browser and your Trezor® device, facilitating a secure connection without compromising the fundamental security principles of hardware wallets.
Unlike browser extensions that might have security vulnerabilities, Trezor Bridge operates as a standalone background application that creates a secure communication channel between web applications like Trezor Suite Web and your hardware wallet. This approach maintains the isolation of your private keys while allowing convenient browser-based access to your cryptocurrency assets.
Trezor Bridge establishes an encrypted local connection between your web browser and Trezor® device, ensuring that sensitive information never leaves your computer unprotected.
The application runs quietly in the background, automatically activating when you attempt to access your Trezor Wallet through a supported web browser.
Trezor Bridge automatically detects when your device is connected and ready for use, streamlining the Trezor Bridge login process.
It supports all major browsers including Chrome, Firefox, Edge, and Brave, ensuring a consistent experience across different browsing environments.
When you first visit the web version of Trezor Suite without Bridge installed, the website will automatically prompt you to install Trezor Bridge. Follow the on-screen instructions for a seamless installation process.
If automatic installation doesn't trigger, you can manually download Trezor Bridge from the official Trezor website. Visit the support section or navigate directly to the Bridge download page.
Trezor Bridge is available for Windows, macOS, and Linux systems. The installation process varies slightly by operating system but typically involves running an installer and following simple prompts.
After installation, restart your browser and navigate to trezor.io/start to verify that Bridge is working correctly. Your device should now be detectable by web applications.
Security Note: Always download Trezor Bridge directly from the official Trezor website to avoid malicious software. Never install Bridge from third-party sources.
