Trezor Bridge is an essential software component that allows your Trezor hardware wallet to communicate securely with your web browser and computer. Without Trezor Bridge, your device cannot properly interact with wallet interfaces such as Trezor Suite or supported third-party applications. This guide explains what Trezor Bridge is, why it is needed, how to install it on different operating systems, and how to troubleshoot common issues.
Whether you are setting up your Trezor device for the first time or facing connection problems, understanding Trezor Bridge is critical for secure crypto management.
Trezor Bridge is a lightweight background application that acts as a communication layer between your Trezor hardware wallet and your computer’s browser. Modern browsers do not allow direct USB communication for security reasons. Trezor Bridge solves this by creating a secure channel that enables data transfer between the device and supported wallet interfaces.Once installed, Trezor Bridge runs automatically in the background whenever your system starts. You generally do not need to open or manage it manually, as it works silently to maintain secure connectivity.
Trezor Bridge plays a vital role in maintaining both usability and security. It ensures that sensitive operations such as transaction signing, address verification, and firmware interactions occur locally on your device rather than through unsafe browser extensions or unknown software.
