Introduction

Trezor Bridge® is an essential utility that facilitates secure communication between your Trezor hardware wallet and desktop or web applications. It ensures that all interactions with your wallet — sending transactions, updating firmware, or managing accounts — are securely transmitted while your private keys remain protected on the device.

Why Trezor Bridge is important

  • Secure USB communication: Provides a trusted channel for web apps and Suite to interact with the device.
  • Cross-platform support: Bridges communication across Windows, macOS, and Linux systems.
  • Minimal exposure: Only allows authorized applications to communicate; user must confirm operations on the device.

Safety first

Important: Always download Trezor Bridge from trezor.io. Avoid third-party sources or links from emails. Verify the TLS certificate in your browser before downloading.

Supported platforms

  • Windows 64-bit
  • macOS
  • Linux (AppImage or packages)

Newer browsers may support direct WebUSB connections, but Trezor Bridge remains the recommended and most compatible method for all systems.
