Introduction — Why this matters
Trezor Bridge historically acted as a small background helper that allowed your Trezor hardware wallet to safely communicate with browsers and desktop apps. Over the years the ecosystem evolved: the Trezor team introduced Trezor Suite for a unified experience and shifted away from a standalone Bridge installation. This guide explains the role Bridge played, how to connect (and migrate) today, and practical troubleshooting steps so you can keep access to your crypto safe.

What is (or was) Trezor Bridge?
In simple terms, Trezor Bridge was a local communication daemon (a background program) that created a secure channel between your Trezor hardware wallet and web browsers or desktop applications. It enabled browser-based pages (when WebUSB support was inconsistent) to talk to a USB device using a stable intermediary, without exposing your device to remote web code.
Why a bridge was useful
Web browsers historically had varying levels of support for direct USB interactions and native integrations. Bridge provided:
- A single local endpoint for Trezor apps to reach the device.
- Better cross-browser compatibility (Chrome, Firefox, etc.).
- Consistency for desktop apps and web apps that relied on the Trezor communication layer.
Where the code lived
The Trezor Bridge / trezord-go project and related communication tools are available from the official Trezor (SatoshiLabs) repositories on GitHub. Those repos include releases, source and build instructions for the daemon used when Bridge was required.
The transition: Trezor Suite & why standalone Bridge is deprecated
As the product suite matured, Trezor introduced Trezor Suite — a dedicated, fully featured desktop and web application that handles device communication internally and reduces the need for a separate Bridge install. Official guidance now recommends using Trezor Suite or Trezor Connect (for third-party integrations) instead of relying on a legacy standalone Bridge. If you are still running a standalone Bridge build, check the official deprecation notes and follow the recommended steps (upgrade to Suite or uninstall Bridge) to avoid future incompatibilities.
Key point: if you’re unsure whether to keep Bridge installed — the safe path is to use the official Trezor Suite or the vendor guidance to update your environment. Uninstalling a deprecated Bridge can prevent conflicts with newer Suite releases.

How to connect your Trezor device (recommended flows in 2025)
Today, there are two mainstream, official ways to connect your Trezor device:
- Trezor Suite (desktop or web): Best for most users — offers a polished UI, firmware updates, and built-in transports.
- Trezor Connect: For third-party wallets and developer integrations — a secure API layer that requests user consent for operations.
Connecting with Trezor Suite (step-by-step)
- Download Trezor Suite for your OS and install it.
- Open Suite and physically connect your Trezor device via USB (or use a supported USB-C cable).
- Follow the on-screen prompts to unlock the device (PIN) and allow the Suite to communicate.
- If a firmware update is suggested, follow the official update flow in Suite — do this only from the official app.
Connecting with Trezor Connect (for third-party wallets)
Many wallets (e.g., MetaMask) support pairing with your Trezor using Trezor Connect. The general flow:
- From the third-party wallet UI choose “Connect Trezor“
- The wallet launches a Trezor Connect prompt to request permission to export public keys / sign a transaction
- Approve actions directly on your Trezor hardware device
Troubleshooting — common issues & fixes
Even simple USB or permission issues can interrupt the connection. Here are practical checks in prioritized order:
1. Physical checks
- Try a different USB cable (charge-only cables lack data lines).
- Use a direct USB port on your computer (avoid unpowered hubs).
2. Software & permissions
- Use the official Trezor Suite app where possible — it bundles compatible transports.
- If using browser flows, confirm the browser has required permissions and that no other extension or app is blocking USB access.
3. Conflicting/legacy Bridge installs
If you have an older standalone Bridge on your machine, it can conflict with Suite. The vendor's deprecation notes outline how to remove the standalone Bridge to avoid problems. Always uninstall legacy versions via the official instructions for your OS.
4. Firmware and device state
If your device needs a firmware update or is in an unexpected boot state, the Suite will usually detect and guide you. Never install firmware or follow update prompts from untrusted sites.
Security: keeping your private keys safe
The Trezor device stores private keys offline — that is the main security benefit. Keep these best practices in mind:
- Only download Suite or Bridge software from trezor.io or official GitHub repositories.
- Never share your recovery seed with anyone. Trezor or support will never ask for it.
- Verify firmware updates inside Suite and confirm the device displays prompts you recognize.
- Use a secure, updated OS and avoid installing unofficial or suspicious utilities that might intercept USB traffic.
Uninstalling deprecated Bridge (short checklist)
- Follow the OS-specific instructions on the official deprecation article.
- After uninstall, install or update to the latest Trezor Suite to restore full functionality.
- Reboot your machine to clear any lingering background processes.
Developer notes & advanced usage
If you develop apps that interact with Trezor, use Trezor Connect (the official integration library) instead of relying on a user-installed Bridge daemon. The Trezor team's repositories (e.g., trezord-go) contain source and examples.
Packaging & distro notes
Some package managers and distro repositories still provide bridge binaries for advanced users, e.g., Homebrew maintains a trezor-bridge formula. Always confirm the origin and checksum of any binary you install.
FAQ — quick answers
Is Trezor Bridge required?
Not usually for users of Trezor Suite. It was previously required for some browser flows, but vendor guidance now recommends Suite or Connect instead.
Where do I get official downloads?
Every official download and guide lives on trezor.io or the Trezor GitHub organization.
My browser doesn't see the device — what next?
Try Suite, check cables/USB, uninstall conflicting Bridge installs, or consult the official support pages for stepwise troubleshooting.
Conclusion — the modern path forward
Trezor Bridge played an important role in connecting hardware wallets to browsers and apps. The ecosystem has matured: Trezor Suite and Trezor Connect provide safer, integrated, and user-friendly channels to manage your devices. If you have a legacy standalone Bridge installed, follow the vendor guidance for uninstalling or migrating to Suite to avoid conflicts. Above all — keep your recovery seed secret and always use official downloads.
