Trezor Bridge — Secure Connection for Your Trezor Hardware Wallet

What is Trezor Bridge?

Trezor Bridge is a small, local application that creates a secure bridge between your web wallet (or manager app) and your Trezor hardware wallet. It makes USB communication reliable across browsers and platforms while keeping your cryptographic secrets strictly on the device.

Browser-friendly

Cross-platform

Encrypted channels

Open-source

Why it matters

Hardware wallets like Trezor isolate private keys from online devices. Bridge ensures the browser can ask the device to sign transactions and verify addresses without exposing keys. It uses ephemeral sessions and strong transport controls so only authorized web apps can talk to your Trezor.

How it works (brief)

After you install Bridge, your browser will request a connection. Bridge validates the request, opens a local secure socket, and forwards messages to the Trezor. All signing happens on-device — the host only receives signatures and public data needed for broadcasting transactions.

Security best practices

Always download Bridge and firmware updates from official Trezor sources. Verify version signatures when prompted, never share your recovery seed with software, and use a strong PIN on the device. When not in use, unplug or lock your Trezor to prevent unattended access.

Frequently asked questions

Do I need Bridge for all browsers?

Bridge makes USB communication stable across many browsers. Some browser-native integrations exist, but Bridge remains the recommended, consistent option for reliable device access.

Is Bridge open-source?

Yes — Bridge's source is public and auditable. Check official repositories and verify release signatures before installing to ensure authenticity.

How do updates work?

Bridge notifies you of updates; always accept updates from the official updater or website and confirm cryptographic signatures when possible.

Can a website steal my seed via Bridge?

No. The seed never leaves the device. Bridge simply forwards browser requests to the device; sensitive operations still require on-device confirmation.

What if Bridge isn't detecting my device?

Try a different USB cable/port, ensure Bridge is running, grant permission prompts in your browser, and check for OS-level permissions or driver needs.
