Download Trezor Bridge — Connect Your Wallet

Trezor Bridge is a small background application that enables secure communication between your Trezor hardware wallet and supported web applications, including Trezor Suite web and browser-based wallets. Install Bridge to ensure reliable device detection and safe transaction signing.

What is Trezor Bridge?

Trezor Bridge acts as a local bridge (helper) between your web browser and the Trezor device when native browser support is limited. It avoids the need for browser plugins and provides a secure, maintained channel for exchanging commands and signing requests.

Get Bridge

Choose your OS and download the latest Bridge installer. Always download from official sources to avoid malicious copies.

Getting Started — Step-by-step

Download Bridge: Get the installer for your OS from the official Trezor download page.
Install: Run the installer. On macOS, approve kernel prompts if asked. On Linux, make AppImage executable or install the DEB package.
Start Bridge: Bridge runs in the background and will show an icon in your system tray/menu bar.
Connect Trezor: Plug in your Trezor device and unlock it with your PIN.
Open Web App: Visit the supported web interface (e.g., Trezor Suite web) and follow the connect prompts which will route through Bridge.
Verify & Approve: Always confirm transaction details on the Trezor device before approving in the browser.

Why Trust Trezor Bridge?

Trezor Bridge is maintained by the Trezor team and is part of the official ecosystem.

The source code is public and subject to audits and community review.

Security checklist

Download Bridge only from the official Trezor website.
Verify checksums and digital signatures when available.
Never install third-party or untrusted versions.
Confirm all transactions physically on the Trezor device.
Keep Bridge and device firmware up to date.

Frequently Asked Questions

1. Do I need Trezor Bridge to use Trezor Suite?

If you use the desktop Trezor Suite app, Bridge isn't required. Bridge is primarily for web-based flows where native USB access is restricted.

2. Is Bridge safe to run on my machine?

Yes. Bridge only facilitates local communication between the browser and your device; private keys never leave the hardware wallet.

3. My browser still doesn't detect the device — what now?

Restart the browser, check that Bridge is running in the system tray, try another USB cable, or reinstall Bridge. Also ensure the browser isn't blocking necessary permissions.

4. Does Bridge collect telemetry?

Bridge aims to minimize telemetry. Check the release notes and privacy policy for specifics on any optional usage data.

5. How do I verify Bridge installer authenticity?

Compare checksums and signatures provided on the official download page with the file you downloaded. Use PGP or SHA256 verification when available.

6. Can I run multiple versions of Bridge?

It's not recommended. Use the latest official release to ensure compatibility and security.
