Trézor Bridge: Secure Your Web3 Experience with Seamless Connectivity
Understanding the Role of Trézor Bridge
If you're using a Trézor hardware wallet and want to interact with browser-based wallets like MetaMask, access decentralized apps (dApps), or confirm blockchain transactions directly from your web browser, you need Trézor Bridge.
Trézor Bridge is a secure, open-source communication interface that connects your physical Trézor device with supported browsers, enabling interaction between the offline wallet and online platforms.
Without it, you won’t be able to use your Trézor wallet in the browser—no Web3, no DeFi, no NFT marketplaces.
Why Trézor Bridge Is Essential for Browser-Based Wallets
The Trézor hardware wallet protects your private keys by keeping them offline. But for online interactions—like signing smart contract transactions or logging into a Web3 app—you need a secure way to communicate with the browser. That’s where Trézor Bridge plays a critical role.
Key features of Trézor Bridge include:
- Enables browser-based interaction with dApps
- Connects Trézor with MetaMask, MyEtherWallet, and others
- Verifies and signs transactions from browser interfaces
- Integrates with Trézor login for passwordless authentication
How to Install Trézor Bridge (Step-by-Step Guide)
Installing Trézor Bridge is quick and secure when done through the official site.
Step 1: Visit the Official Trézor Bridge Page
Go to trezor.io/bridge and choose your operating system: Windows, macOS, or Linux.
Step 2: Download and Install
Follow on-screen instructions to install the software. It runs silently in the background.
Step 3: Restart Your Browser
To activate the connection, restart any open browsers. Ensure pop-ups and scripts are enabled for the bridge to function.
Step 4: Connect Your Trézor Wallet
Plug in your device and try accessing a supported browser wallet or Web3 site. Your wallet should now be detected.
Before Bridge: Complete Wallet Setup via Trézor.io/start
To use Trézor Bridge, you must first initialize your device at Trézor.io/start. This ensures your device has the latest firmware and the correct security configurations.
Steps at Trézor.io/start:
- Install the latest firmware
- Create a new wallet or restore from a seed
- Set up a PIN and passphrase (optional)
- Download and open Trézor Suite
Skipping this initial setup may cause bridge connection issues later.
Using Trézor Bridge with MetaMask
One of the most popular use cases for Trézor Bridge is connecting your Trézor hardware wallet to MetaMask, allowing safe Web3 access.
To connect Trézor with MetaMask:
- Open MetaMask
- Click on your profile icon > "Connect Hardware Wallet"
- Choose “Trézor”
- Select the account(s) and confirm on your Trézor device
- You’re now connected!
All transactions are now signed with your offline private key using Trézor.

For the best experience, use both tools in tandem.
Trézor Login: Enhanced Authentication Through Bridge
Web2 login methods are vulnerable. Trézor login, enabled via Trézor Bridge, allows passwordless sign-in on supported platforms using your wallet.
Benefits of Trézor login:
- No passwords to remember or store
- Immune to phishing
- All logins confirmed on-device
- Compatible with U2F/WebAuthn standards
Check whether your favorite Web3 platform supports Trézor login for the safest authentication.
Enable Staking Securely Through Trézor
Some users stake directly from Trézor Suite, while others prefer third-party dApps. With Trézor Bridge, you can safely use browser-based staking platforms like:
- Lido Finance (ETH)
- Polkadot.js (DOT)
- Yoroi Wallet (ADA)
- Keplr (Cosmos ecosystem)
All staking-related transactions are signed with your Trézor hardware wallet, ensuring non-custodial safet
