The Communication Layer That Links Your Trezor Hardware Wallet to Applications
Trezor Bridge is a background software service that enables communication between your Trezor hardware wallet and supported web applications. It replaces older browser plugins and ensures a stable, secure connection without exposing sensitive information.
Acting as a secure communication channel, Trezor Bridge allows your browser to interact with the hardware wallet while keeping private keys safely stored on the device.
Modern browsers limit direct USB communication for security reasons. Trezor Bridge solves this by serving as a trusted interface between the operating system and browser-based crypto platforms.
When you connect your Trezor device, the Bridge runs quietly in the background. It listens for approved requests from legitimate wallet interfaces and securely forwards them to the hardware wallet.
All sensitive approvals — such as transaction confirmations — still happen directly on the device screen, not on your computer.
Once installed, the Bridge runs automatically when needed and requires no daily management.
This wide compatibility ensures seamless access to crypto services while maintaining device-level security.
Trezor Bridge is primarily required when using web wallet interfaces that connect directly to the hardware wallet. Some desktop apps include built-in support and may not need it separately.
While Trezor Suite is a full wallet management platform, Trezor Bridge is a background communication tool. Suite manages accounts and transactions, while Bridge ensures the device can talk to web apps securely.
Trezor Bridge plays a vital behind-the-scenes role in the Trezor ecosystem. It ensures smooth and secure interaction between hardware wallets and online interfaces without exposing private data.
Though invisible to most users, it is an essential component in maintaining the balance between usability and high-level cryptocurrency security.
