Trezor Bridge - Secure & Smooth Crypto Access

What is Trezor Bridge?

Trezor Bridge is a secure, lightweight software component that enables communication between your computer or web browser and your Trezor hardware wallet. It ensures all sensitive operations are routed safely and encrypted, allowing you to manage your cryptocurrencies with ease.

Because browsers cannot directly communicate with USB hardware wallets securely, Trezor Bridge acts as a local intermediary. It translates web app requests into secure USB commands, ensuring your private keys never leave your Trezor device.

This design minimizes vulnerability to malware or intercepting attacks by performing all critical cryptographic operations on the device itself, following the principle of "What You See Is What You Sign."

Key Features

Cross-platform support: Works on Windows, macOS, and Linux.
Secure encrypted communication between device and computer.
Automatic device detection with minimal setup.
Reduces attack surface compared to direct browser connections.
Open-source codebase for transparency and trust.

How Trezor Bridge Works

When you connect your Trezor hardware wallet, your device is detected by the local Trezor Bridge service. Web applications communicate with this service using secure HTTP requests to perform operations like transaction signing and account management.

All sensitive data, including private keys and signatures, are processed inside the hardware device. Users physically verify every transaction on their Trezor screen before approval, ensuring a secure and user-controlled experience.
