1. What Is Trézór Bridge®™?

1.1 Core Definition

Trézór Bridge®™ is a desktop communication service that creates a secure interface between a hardware wallet and applications requiring access to it. It eliminates browser plugin limitations and improves the overall user experience.

1.1.1 How It Works

The software runs locally in the background, establishing encrypted connections. When an app requests hardware‑wallet access, Bridge mediates the connection.

1.1.1.1 Key Strengths

Lightweight architecture
High compatibility
Enhanced privacy
Trusted by major ecosystems

1.1.1.1.1 Technical Insight

Using local transport channels, Bridge avoids exposing sensitive wallet resources to the broader internet.

2. Why Trézór Bridge®™ Matters

2.1 Solving Browser Limitations

Browsers frequently limit direct USB communication, especially after deprecations of legacy APIs.

2.1.1 Advantages Over Browser Extensions

No dependency on third‑party plugin maintenance
Increased stability when browsers update
Lower attack-surface exposure

2.1.1.1 Streamlined UX

Users experience smoother device detection and fewer connection errors.

2.1.1.1.1 Reduced Permission Requests

Local communication avoids repetitive permission dialogues.

3. Architecture of Trézór Bridge®™

3.1 System Components

Bridge consists of:

Local service daemon
USB communication manager
API gateway interpreter
Update handler

3.1.1 Installation Behavior

The service installs on macOS, Linux, and Windows and launches automatically on system startup.

3.1.1.1 Data Handling

All operations remain confined locally; no user data is transmitted externally.

3.1.1.1.1 Security Boundary

The boundary ensures end‑to‑end isolation.

4. Security Model

4.1 Zero‑Exposure Design

Trézór Bridge®™ is engineered so the wallet never exposes its secrets to your computer.

4.1.1 Encrypted Channels

All information exchanged is:

Encrypted
Verified
Scoped

4.1.1.1 Protection From Malware

Even if malware is present on a system, hardware-wallet signing processes remain isolated.

4.1.1.1.1 User Control

Every action requires manual confirmation on the hardware wallet.

5. Workflow With Applications

5.1 Connecting a Wallet

The typical workflow includes:

Launching a supported wallet application
Plugging in a Trezor device
Automatic Bridge recognition
Application access granted

5.1.1 Supported Use Cases

5.1.1.1 Multi‑Network Support

Bridge integrates across multiple blockchain implementations.

5.1.1.1.1 Developer Flexibility

Developers can extend support through Bridge’s interfaces.

6. Best‑Practice Integration

6.1 For Developers

Developers should:

Use official APIs
Follow signed‑update requirements
Keep user prompts clear

6.1.1 Continuous Updates

Bridge’s updater ensures compatibility with wallet firmware.

6.1.1.1 Testing Strategy
