Trézór Bridge

What Is the Trézór Bridge App?

Trézór Bridge is a small, efficient application that runs on your computer and allows your Trezor hardware wallet to communicate with web interfaces. It replaces outdated browser extensions and serves as a local server that mediates encrypted USB or WebUSB requests.

Why a New Trézór Bridge Application?

Modern Codebase

Rewritten from the ground up for better reliability, performance, and future updates—compatible with new architectures and frameworks.

Browser‑Independent

No more reliance on deprecated Chrome plugins—Trézór Bridge supports Chrome, Firefox, Edge, Brave, and more.

Faster & Leaner

Optimized for minimal resource usage, faster response times, and seamless background operation.

How the Trézór Bridge Works

1. Local server mode: Bridge runs a small local HTTP server to listen for browser/web requests.
2. Encrypted communication: Bridge accepts secure API calls from web apps and translates them to USB commands your Trezor understands.
3. Device handshake: When you connect your Trezor wallet, Bridge authenticates the device and initiates communication.
4. Transaction routing: Requests to send, sign, or exchange pass through Bridge, then require your confirmation on the Trezor device.
5. No key exposure: Private keys never leave your hardware—Bridge only relays commands, not secrets.

Install & Setup Guide

1. Visit the official link: trezor.io/bridge
2. Download the right version for your operating system (Windows, macOS, Linux).
3. Run the installer and follow on-screen instructions.
4. Restart your browser or system if required.
5. Open your Trezor Suite or web app — the Bridge should auto-detect your Trezor device.
6. Authorize any transaction prompts on your hardware for full security.

Security & Best Practices

Trézór Bridge is built for privacy and security, but your practices matter too. Keep these in mind:

• Only download Bridge from the official domain trezor.io/bridge.
• Always verify firmware signatures during setup.
• Confirm transaction details on your Trezor device before approving.
• Keep Bridge and your Trezor firmware consistently updated.
• Avoid downloading Bridge from third-party mirrors or untrusted sources.
• Run reliable antivirus software and avoid malicious or pirated software.
