Trezor Bridge is a communication tool commonly used to connect Trezor hardware wallets with desktop browsers. It acts as a background service that enables compatible wallet interfaces to detect and interact with the device. Its main purpose is to streamline device communication, especially on browsers that do not support direct hardware access.
The Bridge allows your computer’s browser to recognize your Trezor device once it is connected. Without it, some browsers may not detect the hardware wallet, which prevents users from performing critical tasks like device initialization, firmware updates, or transaction confirmations.
It runs quietly in the background, ensuring device access is stable and consistent while using wallet management tools.
While Trezor Bridge enables communication, it does not store or interact with private keys. All sensitive confirmations—such as sending cryptocurrency or updating security settings—must still be approved on the physical hardware device. This provides an important layer of protection, as unauthorized actions cannot be completed without interaction with the hardware wallet.
The Bridge simply relays communication between your computer and the device while maintaining a separation between software and private key storage.
During hardware wallet setup, users may be prompted to install Trezor Bridge if their browser requires it. Once installed, the Bridge typically launches automatically whenever a Trezor device is connected via USB. The software usually requires no additional configuration unless updates are needed.
After installation, users can proceed with device initialization steps such as creating a PIN, generating a recovery seed, and adding accounts.
For daily operations, Trezor Bridge provides a stable connection that supports tasks such as checking balances, generating receiving addresses, and confirming transactions. It helps ensure that communication between the device and wallet interface remains uninterrupted.
This overview is intended to help users understand the general purpose and function of Trezor Bridge and how it fits into the workflow of managing a hardware wallet.
