Trezor Bridge — Secure connection for your Trezor hardware wallet

Connect your Trezor device to Trezor Suite and web wallets, update firmware, and manage crypto — fast, private, and reliable.

What is Trezor Bridge?

Trezor Bridge is the secure connector that lets your browser and desktop apps talk to your Trezor hardware wallet. Whether you need to connect a Trezor device, update device firmware, or open Trezor Suite, Bridge enables that connection while keeping private keys isolated on your hardware device. Use Trezor Bridge to safely sign transactions, confirm addresses, and manage a wide range of crypto assets with a reputable hardware wallet.

Secure

Bridge facilitates secure USB or WebUSB communication with a Trezor device without exposing keys to hosts or browser extensions.

Universal

Works with major browsers and the Trezor Suite desktop application for Windows, macOS, and Linux.

Up-to-date

Keep your Trezor firmware current and enjoy improved compatibility and new coin support through Bridge updates.

How it works

When you launch a wallet interface, the site asks Bridge to open a secure channel to your Trezor. Bridge forwards requests to the device driver layer and returns only encrypted, signed confirmations — never your private key. This two-part design ensures the highest level of security for your crypto assets.

Use Bridge with confidence for secure cold storage workflows, routine transactions, and firmware updates.
