Trezor Bridge

What is Trezor Bridge?

Trezor Bridge is an application created by SatoshiLabs that enables your computer to communicate securely with a Trezor hardware wallet. Unlike the Trezor Suite app or web interface, Bridge works in the background to provide a reliable connection between your browser and your hardware device.

It is required for browsers such as Chrome, Firefox, and Edge to detect and interact with Trezor devices. Bridge ensures that all communication is encrypted and prevents unauthorized access to your wallet.

Why You Need Trezor Bridge

Trezor Bridge is necessary because modern browsers restrict direct USB access for security reasons. Without Bridge, web-based Trezor Suite or other browser integrations cannot connect to your device. It acts as a secure intermediary that allows full device functionality.

• Provides secure USB communication
• Enables browser-based wallet interactions
• Supports multiple devices and sessions
• Ensures encrypted data transfer
• Automatically updates for latest security fixes

Supported Operating Systems

Trezor Bridge supports all major operating systems:

• Windows 10 and 11
• macOS 10.13 and above
• Linux distributions including Ubuntu, Fedora, and Debian

Each OS version provides a dedicated installer that automatically configures your system to communicate with Trezor devices.

Security Best Practices

Security is critical when using Trezor Bridge:

Why Trezor Bridge Is Essential

Without Trezor Bridge, your browser cannot communicate with your hardware wallet. While Trezor Suite desktop app includes this functionality internally, the web-based Trezor Suite relies on Bridge to provide a secure channel for all wallet operations.
