Trezor Bridge — The Secure Gateway to Your Hardware Wallet®

A lightweight, open-source bridge that connects your Trezor device to desktop apps and web interfaces safely and privately.

What is Trezor Bridge?

Trezor Bridge is the secure, official connector that allows your computer and browser to communicate with your Trezor hardware wallet. It handles USB connections, firmware checks, and encrypted command routing so you can manage keys, sign transactions, and interact with decentralized apps without exposing sensitive data.

Built with privacy and simplicity in mind, Trezor Bridge keeps sensitive operations local — your private keys never leave the device. The Bridge works seamlessly with Trezor Suite and supported web wallets, giving a consistent, reliable connection whether you're using Windows, macOS, or Linux.

Why it matters — security & simplicity

  • Security-first design: All signing happens on the hardware wallet. Bridge only transfers encrypted requests and responses.
  • Open-source: Source code is available for review, enabling transparency and community audits.
  • Cross-platform support: Works on mainstream desktop operating systems and integrates with popular web wallets via secure protocols.
  • Minimal footprint: Lightweight and fast — installs in seconds and runs quietly in the background.

Key features

Core capabilities that make Bridge an essential part of your hardware wallet experience:
  • USB communication layer: Reliable connection between your Trezor device and browser-based apps.
  • Automatic firmware checks: Alerts about updates and ensures the device runs authentic firmware.
  • Encrypted command routing: Commands are relayed securely — private keys remain on the device.
  • Compatibility: Supports Trezor Model T, Trezor One, and current Trezor Suite releases.
  • Seamless UX: Simple prompts and predictable workflows lower the barrier to secure crypto management.

Quick setup — get started in 3 steps

  1. Download Trezor Bridge: Click the official download link (or use the Trezor Suite installer). Choose the package for your operating system.
  2. Install & connect: Run the installer. Connect your Trezor device via USB and follow on-screen prompts. Bridge runs in the background and remembers your preference.
  3. Open Trezor Suite or your web wallet: Your connected device will appear automatically. Approve actions directly on your Trezor to sign transactions or confirm settings.

Pro tip: Always download Bridge from the official Trezor website or Trezor Suite to avoid third-party tampering.

  • Peace of mind: Clear separation of keys and host system reduces attack surface.
  • Developer-friendly: Well-documented APIs accelerate integration with wallets and services.
  • Scalable: Works equally well for single users or for managed setups in corporate environments.
