Trezor Bridge — Secure Connection for Trezor Devices

Trezor Bridge is the lightweight connector that lets your computer and browser talk safely to your Trezor hardware wallet. It replaces flaky browser plug-ins with a consistent, secure channel—so actions you take in compatible apps are confirmed on the device where your private keys stay protected.

Why Bridge

Reliable. Private. Purpose-Built.

Stable Device Communication

Bridge speaks directly to your Trezor over USB and exposes a local interface for approved apps. No brittle extensions, fewer surprises.

Security by Design

Your private keys never touch your computer. Bridge simply passes messages while approvals happen on the Trezor screen you control.

Cross-Platform Convenience

Designed to work on popular desktop operating systems with minimal setup. Keep using the tools you know, with a safer connection layer.

Suite & App Friendly

Pairs naturally with desktop and supported web experiences, enabling signing, address verification, and account operations without friction.

Small & Quiet

Runs in the background with a tiny footprint. When you need it, it’s there; when you don’t, it stays out of the way.

Transparent Updates

Install once and receive improvements through routine updates. You remain in control of when and what to install.

From Install to Interaction

Install from an official source. Download Bridge from a verified page you’ve bookmarked. Avoid search-ad links and random mirrors.

Run the installer. Follow the prompts for your operating system. Bridge sets up a small background service that starts with your computer.

Connect your Trezor via USB. Use a cable you trust. If the OS asks for permission, allow communication with the device.

Open your wallet app. Trezor Suite or other supported apps will discover Bridge automatically and request access when needed.

Approve on the device screen. Review addresses, amounts, and metadata on the Trezor itself. Approve only if everything matches exactly.

Pro tip: Keep firmware and desktop apps up to date. Updates often include performance improvements and new protections.

Important: No legitimate support will ever ask for your 12/24-word recovery seed or passphrase. If prompted online, close the page—it’s a scam.

Quick Fixes for Common Issues

Device not detected? Try another USB port or cable, reconnect the device, or restart Bridge and your wallet app.

Browser won’t connect? Close extra tabs using the device, disable conflicting extensions, and ensure only one app is talking to Bridge at a time.

Stuck on “Waiting for device”? Unlock the Trezor with your PIN on the device, and confirm any prompts that appear on its screen.

After an update, things broke? Reboot your computer to restart the background service. If needed, reinstall Bridge from a verified source.

Security check: If a page asks for your recovery seed, stop. Bridge does not require your seed; it only facilitates communication.

Common Questions

Do I need Bridge if I use the desktop app?

The desktop app can handle device communication directly, but Bridge improves compatibility for certain setups and supported web experiences.

Is Bridge a browser extension?

No. It’s a small background service that communicates over a local interface—more stable than extension-only approaches.

Does Bridge ever see my private keys?

No. Keys stay sealed inside your hardware wallet. Bridge only relays messages; sensitive approvals happen on the device.

How do I update Bridge safely?

Use your bookmarked, verified source and review checksums if available. Avoid third-party download sites.

Can multiple apps use Bridge?

Yes, but for reliability, keep only one wallet app interacting with Bridge at a time when signing or managing accounts.

Connect with Confidence

Trezor Bridge makes the path between your computer and your hardware wallet dependable and safe. Install from official sources, verify actions on the device screen, and keep recovery information offline. Simple habits, strong protection.
