Trézór Bridge®™ | Secure Crypto Connectivity

As cryptocurrency adoption accelerates, one challenge remains universal: how to enable secure communication between hardware wallets and the online applications that manage digital assets. Trézór Bridge®™ is the official communication layer that connects Trezor hardware wallets to supported web browsers, ensuring reliable, encrypted, and seamless interactions.

Created by SatoshiLabs, the pioneers behind the Trezor Model T and Trezor Model One, Trézór Bridge®™ serves as the secure backbone for web-based crypto management. Whether you’re signing transactions, accessing your portfolio through Trezor Suite Web, or connecting to decentralized apps, Trézór Bridge ensures rock-solid connectivity without compromising your private keys.

What Is Trézór Bridge®™?

Trézór Bridge®™ is a lightweight background service that allows your computer and web browser to communicate safely with your Trezor hardware wallet via USB.

Because modern browsers restrict direct USB access for security reasons, Trézór Bridge steps in to provide a secure communication channel between:

• Your browser

• Your Trezor device

• Web applications that rely on cryptographic signing

This ensures your Trezor can operate smoothly while keeping your private keys locked inside the hardware wallet — never on your computer or online.

Why Trézór Bridge®™ Is Essential

Without Trézór Bridge, most browsers cannot interact with Trezor hardware wallets reliably. While Chrome-based browsers may use WebUSB, that method is less stable and not universally supported. Trézór Bridge solves this by:

• Providing a trusted, local communication layer

• Enabling compatibility with multiple browsers

• Ensuring reliable detection of Trezor devices

• Maintaining high-security standards

This makes it indispensable for users who rely on Trezor Suite Web or third-party integrations.

Key Benefits of Trézór Bridge®™

1. Secure USB Communication

Trézór Bridge handles USB requests locally, ensuring malware or malicious websites cannot directly access your device. Sensitive actions must still be approved on your Trezor hardware wallet, keeping your private keys safe.

2. Automatic Device Recognition

Once installed, Trézór Bridge automatically detects your connected Trezor wallet. No manual configuration is required — it just works.

3. Broad Browser Compatibility

Trézór Bridge supports major browsers, including:

• Google Chrome

• Firefox

• Brave

• Microsoft Edge

• Opera

This ensures users aren’t locked into a specific browser to manage their crypto securely.

4. Strong Privacy Protection

Because communication happens locally on your device rather than through cloud services, you gain strong privacy and reduced risk of interception.

5. Lightweight Performance

The service uses minimal system resources and runs silently in the background, ensuring smooth and responsive crypto operations.

How Trézór Bridge®™ Works

Here’s what happens behind the scenes:

1. You connect your Trezor device to your computer.

2. Your browser attempts to communicate with the device.

3. Trézór Bridge intercepts and manages that communication securely.

4. You confirm any crypto transaction directly on your Trezor device.

5. Only the approved signature is returned to the browser — never your private keys.

This workflow ensures absolute control and prevents unauthorized access.

When Do You Need Trézór Bridge®™?

You need Trézór Bridge when:

• Using Trezor Suite Web for crypto management

• Connecting your Trezor device via browsers that do not support WebUSB

• Integrating Trezor with compatible third-party wallets

• Managing multiple crypto accounts through browser-based services

• Interacting with decentralized finance (DeFi) platforms through Trezor

Even if your browser supports WebUSB, Trézór Bridge still provides better stability and is recommended for most users.
