Trézór Bridge®™

Trézór Bridge®™

Trézór Bridge®™ is a secure communication layer designed to connect Trézór hardware wallets with modern web browsers and desktop environments. It plays a vital role in enabling users to manage digital assets safely while maintaining full control over private keys and transaction approvals.

What Is Trézór Bridge®™

Trézór Bridge®™ is a background service that enables communication between a Trézór hardware wallet and supported web interfaces. Modern browsers restrict direct USB access for security reasons, which makes an intermediary layer essential for safe device interaction.

The bridge runs locally on the user’s computer, listening for authorized requests from compatible applications. When a request is received, it securely relays information to the hardware wallet without exposing private data to the browser or external servers.

Core Purpose

Enable secure USB communication with hardware wallets
Protect private keys from browser-level exposure
Support multiple operating systems seamlessly
Maintain compatibility with Trézór web tools

How Trézór Bridge®™ Works

When installed, Trézór Bridge®™ operates quietly in the background. It monitors local ports for authorized requests originating from approved Trézór-compatible applications. Once a connection is established, the bridge facilitates encrypted data transfer between the application and the hardware wallet.

All critical actions, including transaction signing and address verification, are executed directly on the hardware wallet. This design ensures that even if a browser environment is compromised, private keys remain fully protected.

Operational Flow

User connects Trézór device via USB
Bridge detects and authenticates the device
Web application sends a signed request
User confirms actions on the device screen

Security Architecture

Security is the foundation of Trézór Bridge®™. The architecture is intentionally minimal, reducing the attack surface while maintaining robust communication capabilities. The bridge does not store private keys, passwords, or recovery data, ensuring that sensitive information never leaves the hardware wallet.

Local Isolation

The bridge operates entirely on the user’s local machine. No cloud-based routing or remote servers are involved, minimizing exposure to external threats.

Encrypted Channels

All data transmitted between the wallet and applications is encrypted, protecting transaction details and device communication from interception.

User Verification

Every critical operation requires manual confirmation on the Trézór device itself, ensuring that unauthorized actions cannot be executed silently.

Compatibility and Platform Support

Trézór Bridge®™ is designed to support a wide range of operating systems, including Windows, macOS, and Linux. This broad compatibility ensures that users can access their digital assets regardless of their preferred computing environment.

The bridge is regularly updated to maintain compatibility with new browser versions and evolving security standards. These updates help ensure a stable and reliable connection between hardware wallets and supported applications.

Supported Environments

Windows desktop systems
macOS devices
Linux distributions
Major modern web browsers

User Experience and Reliability

Trézór Bridge®™ is designed with a focus on simplicity and reliability. Once installed, it requires minimal user interaction, allowing individuals to focus on managing their digital assets rather than troubleshooting connectivity issues.

The service starts automatically with the operating system, ensuring that the bridge is available whenever the hardware wallet is connected. This approach provides a smooth and consistent user experience across sessions.
