Trezor Bridge® — Connect Your Web3 World Securely™

The rise of Web3 has transformed how we interact with blockchain-based applications, decentralized finance (DeFi), and NFTs. While this new ecosystem opens exciting opportunities, it also introduces security challenges. Trezor Bridge® provides a secure, encrypted communication layer that connects your Trezor hardware wallet to Web3 applications safely, allowing users to manage assets, interact with dApps, and sign transactions without exposing private keys.

This guide provides a comprehensive overview of Trezor Bridge®, its installation, security features, integration with Web3 platforms, and best practices to ensure safe cryptocurrency management.

1. Understanding Trezor Bridge®

Trezor Bridge® is a middleware application that enables secure communication between your Trezor hardware wallet and desktop/web applications. It ensures that sensitive information, including private keys, never leaves your device while allowing you to interact with Web3 platforms. Bridge supports modern browsers and operating systems, providing cross-platform compatibility and encrypted communication channels.

Key capabilities include:

• Secure connection to Trezor Suite and Web3 dApps
• Encrypted communication and transaction signing
• Firmware updates delivered securely
• Integration with developer tools and APIs
• Support for multi-chain interactions in the Web3 ecosystem

2. Why Trezor Bridge® is Vital for Web3

In the Web3 environment, users interact with decentralized applications that often require signing transactions or connecting wallets. Trezor Bridge® ensures:

• Secure and encrypted communication between hardware and applications
• Protection of private keys at all times
• Seamless Web3 access across multiple browsers and operating systems
• Support for advanced features like passphrases and hidden wallets
• Safe firmware and application updates

Without Bridge, private keys could be exposed to malicious web pages or malware, making the hardware wallet vulnerable.

3. Installing Trezor Bridge®

Installing Bridge ensures secure connectivity:

1. Visit trezor.io/bridge and download the installer for your operating system.
2. Run the installer and follow the instructions to complete installation.
3. Restart your browser or application to initialize Bridge.

Once installed, Trezor Bridge® runs in the background, enabling smooth communication with your hardware wallet and Web3 applications.

4. System Requirements

• Operating Systems: Windows 10+, macOS 10.15+, Linux distributions

• Hardware Wallets: Trezor One and Model T
• Internet Connection: Required for firmware updates and broadcasting transactions

5. How Trezor Bridge® Works with Web3

Trezor Bridge® functions as a secure intermediary between your hardware wallet and Web3 applications:

1. User initiates a connection to a Web3 dApp or platform.
2. Bridge encrypts the request and sends it to the Trezor wallet via USB.
3. The wallet verifies the request, and the user approves it on the device screen.
4. Signed transactions or account information are sent back through Bridge to the application.

This process ensures that all operations requiring private keys remain offline, reducing the risk of exposure to malicious websites.

6. Security Features

• Encrypted end-to-end communication between device and apps
• Device authentication to prevent unauthorized connections
• Private keys never leave the hardware wallet
• Support for firmware updates and secure app interactions

8. Migration and Device Upgrades

When upgrading to a new Trezor device, Bridge ensures a secure migration:

1. Back up your recovery seed from the old device.
2. Install the latest Trezor Bridge® version.
3. Connect your old device to Trezor Suite or a Web3 platform to verify assets.
4. Connect the new device and restore using the recovery seed.
5. Confirm all accounts, balances, and assets are correctly restored.
6. Apply firmware updates via Bridge to the new device.
