Trezor Bridge — Secure Connection for Your Trezor

What Is Trezor Bridge?

Trezor Bridge is a lightweight software developed by SatoshiLabs that allows your browser to communicate with your Trezor hardware wallet. It's essential for interacting with the Trezor Suite, browser extensions, and third-party apps like Metamask or MyEtherWallet.

Without Trezor Bridge, your web browser cannot recognize or interact with your device. It acts as a secure channel, enabling cryptographic operations to be approved on your Trezor device while keeping your private keys isolated from the internet.

Key Features

Bridge connects your device to Chrome, Firefox, Brave, and other compatible browsers.

End-to-end encryption ensures your private keys and sensitive data are never exposed.

Runs in the background with minimal CPU and memory usage.

Fully auditable codebase ensures transparency and trust for every user.

How to Install Trezor Bridge

Go to the official Trezor download page: trezor.io/bridge
Select your operating system (Windows, macOS, Linux).
Download the installer and run the setup file.
Follow on-screen instructions to complete installation.
Restart your browser for Bridge to activate.

Why Is Trezor Bridge Important?

Unlike browser extensions, which can be limited or vulnerable, Trezor Bridge offers a secure, local communication channel between your hardware wallet and the browser. It removes the need for WebUSB and provides a fallback in case native communication fails.

✔️ Improves compatibility across platforms
✔️ Maintains full privacy and security
✔️ Acts as a foundation for dApp and wallet integration
✔️ Offers ongoing updates from the Trezor team

✅ Never install Bridge from unofficial or third-party websites.
✅ Keep your computer and Trezor firmware up to date.
✅ Avoid using Bridge on public or shared computers.
✅ Disconnect your device when not in use for added protection.
