Trezor Bridge

What Is Trezor Bridge?

The Trezor Bridge is a lightweight, official software utility that enables your operating system and browser to communicate with your Trezor hardware wallet. Unlike browser-only plugins or legacy systems, Trezor Bridge ensures secure, standardized USB communication while keeping your private keys isolated on the Trezor device.

With Trezor Bridge, you gain compatibility across all major platforms — Windows, macOS, and Linux — making your hardware wallet functional with Trezor Suite or supported web wallets. ([trezor.io](https://trezor.io/bridge))

Because Trezor Bridge handles all USB-level communication, your crypto management interface (like Trezor Suite) interacts seamlessly without bridging the gap manually. This makes the Trezor Bridge indispensable for everyday secure crypto use.
