Connecting Trezor Bridge to Browser Wallets

Trezor is known for its powerful hardware wallet security. But what if you want to use your Trezor with browser-based wallets like MetaMask or other decentralized finance (DeFi) platforms? That’s where Trezor Bridge comes in — it acts as the communication channel between your Trezor device and browser wallet interfaces.

In this guide, we’ll walk you through what Trezor Bridge is, why it's needed, and how to connect your Trezor to popular browser wallets securely and effectively.


What Is Trezor Bridge?

Trezor Bridge is a lightweight background service that allows your browser to communicate with your Trezor hardware wallet. It is essential for web-based wallet interfaces to detect and interact with your physical Trezor device.

When installed and running correctly, Bridge allows browser extensions or dApps to prompt secure transaction signing through your Trezor, without exposing your private keys.


Why Connect Trezor to a Browser Wallet?

Browser wallets like MetaMask offer convenience and support for a wide range of networks and decentralized applications. By connecting your Trezor to these wallets, you can:

  • Interact with dApps while keeping your private keys offline
  • Approve transactions securely using your Trezor device
  • Use hardware-level security with popular tools like MetaMask, Rabby, or other Web3 wallets
  • Manage tokens and NFTs while minimizing security risks

This hybrid approach gives you the best of both worlds: convenience + security.


Prerequisites Before Connecting

To successfully link Trezor with a browser wallet, ensure the following:

  • Trezor Bridge is installed and running
  • Browser is compatible (usually Chrome, Firefox, Brave)
  • Your Trezor firmware is up to date
  • Browser wallet (e.g., MetaMask) is installed and unlocked
  • Your Trezor device is plugged in and unlocked

Step-by-Step: Connecting Trezor to MetaMask (Example)

Let’s walk through connecting your Trezor to MetaMask — one of the most widely used browser wallets.

Step 1: Launch MetaMask Extension

Open your MetaMask extension and ensure you're logged in.

Step 2: Click ‘Connect Hardware Wallet’

In the MetaMask menu, find the option labeled "Connect Hardware Wallet." This will prompt a list of supported devices.

Step 3: Choose Trezor

Select Trezor from the list of hardware wallets and proceed.

Step 4: Authorize Connection via Trezor Bridge

Once selected, MetaMask will try to communicate with your Trezor via Trezor Bridge. You may see a popup or tab asking you to:

  • Authorize your device
  • Confirm your Trezor PIN
  • Select an account or address to import

This process allows MetaMask to display your Trezor-managed account without exposing your keys.

Step 5: Complete Import

After confirming the action on your Trezor device, MetaMask will show the imported Trezor address. Now you're ready to use it like a standard MetaMask account — except all private key actions (like signing) must be approved on the Trezor itself.


Other Wallets That Work with Trezor Bridge

Trezor Bridge can also connect with other browser wallets and interfaces:

  • Rabby Wallet
  • MyEtherWallet (MEW)
  • MyCrypto
  • WalletConnect (through third-party apps)
  • Various Web3-enabled dApps that offer hardware wallet login

Each tool may have slightly different steps, but the concept is the same: connect your Trezor through Bridge, authorize via device, and interact securely.
