Trezor® Bridge — connect your Trezor to the Web safely

Trezor® Bridge is the lightweight background service that lets your Trezor hardware wallet communicate with desktop apps and supported browsers. It provides a secure, reliable channel so you can use Trezor Suite, interact with dApps, sign transactions, and manage assets — while your private keys remain on the device.

Overview

Trezor® Bridge acts as a translator between your computer and your hardware wallet. Many browser-based Web3 applications rely on a secure bridge to communicate with hardware wallets; installing Bridge ensures compatibility and stability across browsers and operating systems. It’s intentionally simple — install, connect your device, and Bridge handles the rest.

Who should use it?

Anyone who uses a Trezor device with desktop software or browser dApps will benefit. Whether you use Trezor Suite, decentralized exchanges, NFT platforms, or wallet integrations, Bridge is the service that makes the connection secure and reliable.

Key Features

  • Secure handshake: Bridge authenticates the connection between apps and your device so requests are legitimate.
  • Browser interoperability: Enables WebUSB and WebHID connections used by modern dApps and wallet integrations.
  • Low footprint: Runs quietly in the background without heavy resource use.
  • Automatic updates: Keeps pace with browser and OS changes to avoid interruptions.
  • Community-audited: Open-source development lets security researchers inspect behavior.

Step-by-step setup

  1. Download: Visit the official Trezor site and select Bridge for your OS.
  2. Install: Run the installer and allow the background service to start.
  3. Connect: Plug in your Trezor device using the supplied cable.
  4. Open apps: Launch Trezor Suite or your chosen Web3 app — Bridge will establish the link.
  5. Confirm on-device: Always verify transaction details on the Trezor screen before approving.

Installation typically takes only a few minutes. After that, Bridge maintains the secure channel each time you connect your device.

Security & best practices

  • Never share your recovery seed: Bridge never asks for seeds — if asked, stop and report.
  • Verify on-device: Check addresses and amounts on the Trezor screen before confirming.
  • Use official downloads: Only install Bridge from trezor.io to avoid tampered files.
  • Keep software updated: Apply updates for Bridge, Trezor Suite, and firmware promptly.
  • Use passphrases if needed: For extra compartmentalization, enable an optional passphrase on your device.
