Welcome to the official landing page for Trezor Bridge, the dedicated software that links your Trezor hardware wallet to your computer and browser environment. This page provides a detailed 800-word guide covering what the Bridge is, why you need it, and how to install and use it securely. If you want to interact with decentralized applications, manage crypto portfolios, or send and receive assets with peace of mind, the Bridge ensures a secure channel between your device and your apps.
What Is Trezor Bridge?
Trezor Bridge is a lightweight background service that runs locally on your computer. Its primary purpose is to handle communication between your browser or desktop application and your Trezor device. Without it, applications cannot speak directly to your hardware wallet. The Bridge ensures that every interaction is authenticated, secure, and user-consented. It is open-source, transparent, and designed with privacy in mind — no data is collected or transmitted beyond what is required to establish local communication.
Why Do You Need It?
Modern browsers and desktop apps require a reliable method to communicate with external devices. The Bridge fills this gap by acting as a secure messenger. It translates app requests into instructions your Trezor can understand and sends responses back. The Bridge is essential for:
- Initializing new wallets and restoring from recovery seeds.
- Signing transactions across Bitcoin, Ethereum, and many altcoins.
- Authorizing logins to Web3 decentralized apps (dApps).
- Ensuring firmware updates are delivered safely.
Installation Guide
Security Advantages
The Bridge is more than just a connector. It actively enhances your security posture:
- On-device verification: All sensitive operations require confirmation on the Trezor screen, eliminating blind approvals.
- Local-only communication: The Bridge does not upload keys or secrets to external servers.
- Minimal permissions: It only handles communication between your apps and your wallet, reducing attack surface.
- Regular updates: Security patches and improvements are delivered quickly via official installers.
Best Practices for Safe Usage
To maximize your safety while using Trezor Bridge, follow these practices:
- Download Bridge installers exclusively from Trezor.io.
- Keep your Bridge and firmware updated to the latest versions.
- Confirm every transaction on your device screen, never relying solely on your computer’s display.
- Revoke dApp sessions you no longer use, and never approve suspicious requests.
- Use a clean, trusted computer environment free of malware.
