Trézór Bridge®™ | Secure Crypto Connectivity

Trézór Bridge®™ is the official software gateway that enables secure communication between your Trezor hardware wallet and your computer or browser. Acting as a bridge, it ensures your transactions, wallet management, and crypto operations are executed safely, without exposing sensitive private keys to online threats.

This guide provides a complete overview of Trézór Bridge, its features, how it works, and why it is a critical component in the Trezor ecosystem.

What Is Trézór Bridge®™?

Trézór Bridge®™ is a lightweight application that connects Trezor hardware wallets to the Trezor Suite, browsers, and other crypto applications. It facilitates secure communication while keeping private keys offline on the hardware device.

Unlike browser-based wallets or software wallets, Trézór Bridge does not store sensitive information—it only relays signed transactions between your device and the interface you are using.

Why Trézór Bridge®™ Is Essential

Hardware wallets are only as secure as their connection to your devices. Trézór Bridge ensures:

• Safe communication between hardware wallet and computer
• Real-time verification of transactions
• Compatibility with multiple browsers and platforms
• Prevention of phishing and malware attacks during transactions

Essentially, it acts as a trusted middleware between your Trezor device and the digital world.

How Trézór Bridge®™ Works

Step 1: Installation

• Download Trézór Bridge from Trezor.io/start
• Install on your desktop (Windows, macOS, Linux)

Step 2: Connection

• Connect your Trezor device via USB or compatible interfaces
• Trézór Bridge detects your device automatically

Step 3: Transaction Relay

• All wallet operations (sending crypto, signing transactions, or accessing DeFi apps) are sent to the Trezor device
• The device signs transactions offline, and Trézór Bridge relays them to the network

This design ensures private keys never leave the device, reducing risk of online attacks.

Key Features of Trézór Bridge®™
