Trezor Bridge: Complete Guide to Secure Hardware Wallet Connectivity

Introduction to Trezor Bridge

Trezor Bridge is an essential software component that enables seamless communication between your Trezor hardware wallet and your web browser. Developed by SatoshiLabs, Trezor Bridge acts as a secure intermediary, ensuring that your device can safely interact with web-based wallet interfaces such as Trezor Suite and supported third-party applications.

Without Trezor Bridge, your browser would not be able to detect or communicate with your Trezor device properly. This makes it a critical tool for managing cryptocurrencies securely, signing transactions, and accessing advanced wallet features.
