Trézor Bridge® | Secure Hardware Wallet Connection

A focused guide to connecting your hardware wallet securely to web and desktop apps

Why Trézor Bridge matters

Trézor Bridge is the lightweight, secure connector that links your Trezor hardware device to web wallets and browser-based services. Designed to remove complexity while preserving the strongest safety guarantees, the Trézor Bridge® workflow prevents private keys from ever leaving the device. This page explains how the Secure Hardware Wallet Connection works, what makes it resilient, and how to get started in minutes.

How the Secure Hardware Wallet Connection works

The core idea behind a secure hardware wallet connection is separation of duties: cryptographic operations (signing, key generation) happen inside your Trezor device; the host computer and browser only display transaction details and pass encrypted signatures. Trézor Bridge establishes an authenticated channel between your browser and the device, enumerates available wallets, and safely forwards user-approved commands. Because the Bridge acts as a thin, audited intermediary, security remains robust without sacrificing convenience.

Key benefits at a glance

Device-first security — Private keys never leave the hardware.
Cross-platform — Works with Windows, macOS and Linux desktop browsers.
Compatibility — Integrates with popular wallets and dApps through standard APIs.
Transparent — Minimal software surface, clear permission prompts, auditable behavior.

Step-by-step: Quick setup

  1. Install the official Trézor Bridge application or use the browser extension if available.
  2. Connect your Trezor device via USB and unlock it with your PIN.
  3. Open the web wallet or service and choose “Connect hardware wallet.”
  4. Approve the connection on your device screen — verify addresses and sign only when certain.
Security hygiene (recommended)

Always download Trézor Bridge from the official source, verify software signatures when possible, and keep your device firmware updated. Never share your seed phrase or enter it into a computer.

Real-world usage

Developers and users alike value the Trézor Bridge® connector for enabling a reliable Secure Hardware Wallet Connection across decentralized applications. Whether you’re swapping tokens, interacting with smart contracts, or signing documents, Bridge reduces integration complexity while keeping your keys isolated on the device.

Frequently Asked Questions

1. What is Trézor Bridge and why use it?

Trézor Bridge is a small connector that enables communication between the Trezor hardware wallet and web applications. Use it to maintain a secure hardware-based signing process while using browser-based wallets and dApps.

2. Is Trézor Bridge safe to install?

Yes — when downloaded from the official Trezor website. The Bridge has a limited scope, minimal privileges, and is designed to expose only the necessary API for hardware wallet interaction.

3. Which browsers and platforms are supported?

Trézor Bridge supports major desktop browsers on Windows, macOS, and Linux. Mobile environments typically use alternative connection methods like WebUSB or BLE when supported.

4. My browser can’t detect the device — what should I do?

Ensure Bridge is running, the device is unlocked, and any blocking extensions are disabled. Restart the browser and reconnect the device; consult official troubleshooting guides if the problem persists.

5. How do I verify the connection is secure?

Always confirm transaction details on the Trezor device screen before approving. The Trézor Bridge simply relays commands — your physical device shows the final data to sign, which is the true security checkpoint.
