Trezor Bridge

A simple guide — what it is, how to install, and how to keep it secure.

Quick guide

What is Trezor Bridge?

Trezor Bridge is a lightweight local application that enables your Trezor hardware wallet to communicate with web apps through your browser. It acts as a secure bridge between the device and web-based wallet interfaces.

Why it matters

  • Enables browser access to your Trezor device without exposing keys to the web.
  • Works with popular wallet interfaces and Trezor Suite.
  • Runs locally — connections are established on your machine only.
Download & Install FAQ Security tips
Latest tested browsers: Chrome, Edge, Brave, and Firefox. If your browser blocks the connection, check extensions or security settings.

Security tips

Keep your hardware wallet and the bridge secure with a few simple practices:

  • Download Trezor Bridge only from official sources and verify checksums.
  • Keep your operating system and browser up to date.
  • Use a strong, offline backup of your recovery seed — never store it digitally.
  • Disable browser extensions that can inject scripts when using web wallets.

Troubleshooting

If your device is not recognized: unplug and replug the device, try a different USB port or cable, restart the browser, or reinstall Trezor Bridge.

FAQ

For most browser setups, yes — it simplifies communication between your Trezor device and web wallets. Some apps may offer native support for certain browsers without Bridge.
Trezor Bridge itself runs locally, but to interact with online services you will of course need an internet connection. The bridge doesn't upload your keys or seed.

Developer note

If you're integrating with the Trezor device programmatically, ensure you follow the official API and user prompts to maintain user consent.
