Trezor Bridge — Comprehensive Guide | Official Site®

What is Trezor Bridge?

Trezor Bridge is a lightweight but critical software component that acts as the secure communication link between your Trezor hardware wallet and your computer or browser-based cryptocurrency wallets. It ensures your private keys never leave your device while validating and signing transactions securely.

Without Trezor Bridge, your computer cannot recognize or safely communicate with your Trezor device, making it an essential part of your hardware wallet setup. Compatible with Windows, macOS, and Linux, Trezor Bridge runs silently in the background, enabling seamless crypto management.

• Establishes a secure channel between your Trezor hardware wallet and crypto software.
• Enhances compatibility with popular web browsers and wallet interfaces that rely on USB communication.
• Prevents direct exposure of your private keys and critical signing operations to your computer or network.
• Allows Trezor Suite and third-party apps to detect and interact with your device smoothly.
