Trezor BridgeSecure connection for your hardware wallet

Trezor Bridge is the lightweight piece of software that allows your Trezor hardware wallet to communicate with web applications in a secure way. This page explains installation, basic troubleshooting, and why it matters for keeping your crypto safe.

What is Trezor Bridge?

At its core, Trezor Bridge runs on your computer and acts as an intermediary between your browser and the physical Trezor device. Without it, most modern browsers won't be able to access the device over USB. Think of it as the small but crucial translator that keeps things secure and simple.

Why it matters

  • Secure communication: Only the necessary messages are forwarded; private keys never leave the device.
  • Compatibility: Works with modern browsers and standard OS USB stacks.
  • Simple updates: Keeps the device-compatible layer up to date without heavy installs.

Security notes

Never share your recovery seed with anyone. Trezor Bridge only facilitates communication — it never needs to know your seed. Keep your Bridge updated and only download it from the official Trezor website to avoid tampered installers.

Pro tip: When troubleshooting, check your OS-level USB permissions and any browser extensions that might interfere with device access.
