Trézor Bridge: Official Trézor Connection Software

Introduction to Trézor Bridge

Trézor Bridge is the official, lightweight software developed by SatoshiLabs to facilitate secure communication between Trézor hardware wallets and web-based applications. As the backbone of Trézor connectivity, it enables users to interact with cryptocurrencies through browsers without exposing private keys to online risks. This background service runs locally on your computer, acting as a secure intermediary for transactions, firmware updates, and device management.

Designed for simplicity and security, Trézor Bridge supports both Trézor One and Trézor Model T devices. It integrates seamlessly with web wallets, exchanges, and decentralized apps (dApps), allowing you to send, receive, and manage crypto while keeping your assets offline. Unlike direct connections that might introduce vulnerabilities, Bridge uses encrypted protocols to ensure data integrity.

Whether you're a beginner setting up your first wallet or an advanced user engaging in DeFi activities, Trézor Bridge provides the essential link. It's open-source, regularly updated, and free to use, making it a trusted tool in the crypto ecosystem.

How Trézor Bridge Operates

At its core, Trézor Bridge functions as a local HTTP server that listens for requests from web browsers. When you connect a Trézor device, Bridge establishes a secure tunnel using protocols like WebUSB or UPnP. It translates device interactions into web-compatible commands, enabling apps to request signatures or data without direct access to your hardware.

Key operational principles:

• Local Processing: All sensitive operations occur on your device; Bridge only relays approved data.

• Encryption: Communications are encrypted to prevent interception.

• Platform Agnostic: Compatible with Windows, macOS, and Linux, with no mobile version yet.

• Automatic Detection: Recognizes connected devices instantly and handles multiple units.

• Minimal Footprint: Runs in the background with low CPU usage.

Bridge is invisible during use—users interact through web interfaces, while Bridge handles the heavy lifting behind the scenes.

Core Features of Trézor Bridge

Trézor Bridge offers a suite of features that enhance hardware wallet usability:

• Secure Transaction Signing: Allows web apps to initiate sends or receives, with confirmation on the device screen.

• Device Management: Supports PIN entry, passphrase setup, and firmware updates directly from browsers.

• Multi-Currency Support: Works with over 1,000 coins, including Bitcoin, Ethereum, and altcoins.

• Error Reporting: Provides detailed feedback for issues like connection failures or invalid inputs.

• Integration Ready: Connects to tools like MetaMask, MyEtherWallet, and exchange platforms.

• Firmware Tools: Enables over-the-air updates to keep devices secure.

These features make Bridge a versatile connector for everyday crypto tasks and advanced operations like staking or NFT trading.
