What is Trezor Bridge?

Trezor Bridge is a small, official helper application that enables communication between your Trezor hardware wallet and web wallets or desktop clients. It runs locally and ensures requests are securely proxied to the device so private keys never leave the hardware.

Download & Install

Select the installer that matches your operating system. Always download from the official Trezor domain to avoid tampered packages.

Windows Installer (.exe) macOS Installer (.pkg) Linux (.deb / .AppImage)

Quick Troubleshooting

  • If the browser can't detect your device, make sure Bridge is running (check system tray / background services).
  • Restart the Bridge service or your browser if connections fail.
  • Ensure firmware on your Trezor and the Bridge app are up to date.
  • On macOS, allow the installer in System Preferences > Security & Privacy if blocked.

Security Notes

Bridge only facilitates local communication — it does not access or transmit your recovery seed. Never install unofficial or modified Bridge builds. Verify signatures when available.
