Trezor Bridge — What it is and why you need it

Trezor Bridge is a locally installed helper that enables secure communication between your Trezor hardware wallet and desktop or browser apps. It translates requests into USB messages your device understands, while ensuring all sensitive actions remain confirmed on-device.

Overview — how Trezor Bridge works

Trezor Bridge runs locally on your machine, providing an API that Trezor Suite or web apps use to communicate with your device. It ensures your private keys never leave the hardware wallet and that transaction requests are safely routed.

Installing Trezor Bridge

  1. Go to the official Trezor website.
  2. Download the correct installer for Windows, macOS, or Linux.
  3. Run the installer and approve USB permissions.
  4. Restart your browser or Trezor Suite after setup.

Always download Trezor Bridge from trezor.io — never from third-party sites.

Security considerations

Bridge itself doesn’t hold your seed or keys — all signing happens on-device. Always confirm prompts on your Trezor screen and ignore any request for your recovery phrase, which is a red flag for phishing.

Troubleshooting common issues

  • Device not detected: Check your cable/port and restart Bridge.
  • Browser issues: Update or restart your browser.
  • Permissions: On macOS/Linux, adjust USB permissions if prompted.
  • Outdated Bridge: Reinstall the latest version from the official site.
