What is Trezor Bridge?
Trezor Bridge is the official communication interface between your browser and your Trezor hardware wallet. Unlike browser extensions that pose security risks, Trezor Bridge ensures a secure, isolated connection that enables seamless functionality with the Trezor Suite or any supported third-party app.

Why You Need Trezor Bridge
- Enhanced Security: No browser extensions. Trezor Bridge works in the background, reducing attack surfaces.
- Compatibility: Works on Windows, macOS, and Linux with major browsers like Chrome and Firefox.
- Simplified Access: Automatically detects your Trezor device and helps you launch the Trezor Suite.
- Open-source: Like all Trezor products, Bridge is fully transparent and auditable.
How Trezor Bridge Works
Trezor Bridge installs a lightweight daemon on your device. When you navigate to Trezor.io/start or open Trezor Suite, it listens for your hardware wallet. Once connected, it allows you to securely access and manage your crypto assets through the Trezor interface, without relying on browser extensions.
Setting Up Trezor Bridge
- Visit Trezor.io/start
- Download Trezor Bridge for your OS
- Install and refresh your browser
- Connect your Trezor hardware wallet
- Launch Trezor Suite and begin managing your crypto safely

Trezor Bridge vs Browser Extensions
Browser extensions are prone to phishing, hijacking, and malicious updates. Trezor Bridge eliminates these risks by functioning outside of your browser's environment. Your private keys stay on the hardware device, never exposed to your browser or system memory.
Use Cases and Compatibility
- Trezor Suite: Full wallet functionality with account management, receive/send crypto, token management.
- Third-party apps: Compatible with Electrum, Exodus, MetaMask (with Trezor), and more.
- Firmware updates: Secure delivery of firmware without exposing your wallet to the internet.
