Trezor Bridge — Comprehensive Guide

Trezor Bridge is a lightweight local application that creates a secure channel between your computer and Trezor hardware wallet. It ensures that all communication is authenticated and signed, maintaining the integrity and security of your transactions.

The main purpose of Trezor Bridge is to abstract USB communication, handle browser quirks, and provide a consistent interface for web applications. This guarantees a safe and seamless experience for users, while preventing malicious access to your private keys.

By using Trezor Bridge, users gain confidence in every interaction with their hardware wallet, as it enforces device verification and secure transaction approval directly on the Trezor device.

Always download Trezor Bridge from the official website. Select the installer compatible with your operating system, run the setup, and follow instructions. After installation, the service will run locally and enable browsers to detect your Trezor automatically.

Make sure your system is up-to-date and that your Trezor firmware is current. Confirm any on-device prompts to authorize communication and always verify transaction details before approving.

Checklist for safe usage:

• Only download from official Trezor domains.
• Verify installer checksums if available.
• Confirm transactions directly on your Trezor.
• Use HTTPS web apps only.

Is Trezor Bridge required? While some web apps can use WebUSB, Trezor Bridge ensures compatibility across all browsers and platforms, making it the recommended option.

Does Bridge access private keys? No. Trezor Bridge only forwards messages. All private keys remain securely on the Trezor device.

How do I trust the installer? Download only from official Trezor websites, verify checksums if provided, and avoid unverified third-party sources.
