Unofficial Educational Presentation
Trezor Bridge is commonly described as a background service that enables communication between a web browser and a connected hardware wallet. It acts as a secure connection layer that allows supported web interfaces to interact with the device.
This page presents an educational overview of how such a bridge service functions within a hardware wallet ecosystem. It does not provide official setup instructions or downloads.
Modern browsers have limited direct access to USB hardware for security reasons. A bridge application fills this gap by acting as an intermediary between the browser and the physical device.
In practice, this allows web-based wallet interfaces to request public information, initiate transactions, and display device prompts—while cryptographic operations remain on the hardware wallet itself.
The bridge runs locally on the user’s computer and listens for authorized requests from supported applications.
When installed, the bridge service operates quietly in the background. A supported browser interface sends requests to the local bridge, which then forwards them to the connected hardware wallet.
The wallet displays all critical actions on its screen, requiring physical confirmation from the user. This ensures that no transaction or sensitive action can occur without direct user approval.
Once confirmed, the response is sent back through the bridge to the browser interface.
The bridge model helps maintain strong security boundaries. Private keys never leave the hardware wallet, and signing operations are isolated from the computer and browser environment.
Users are typically advised to keep bridge software updated and to install it only from verified sources. Outdated or unofficial software may expose users to security risks.
Clear device confirmations and warning screens are essential safeguards against phishing and malicious web requests.
Trezor Bridge is commonly used when accessing a hardware wallet through a web interface rather than a desktop application. It enables seamless device detection and interaction.
Users may rely on the bridge for account viewing, transaction approval, and device management tasks, depending on the software ecosystem.
Some modern environments may use alternative technologies, but the bridge concept remains an important part of understanding hardware wallet communication.
Trezor Bridge represents an important architectural component that allows secure communication between web applications and hardware wallets.
By acting as a controlled intermediary, it helps preserve the security model of hardware wallets while maintaining usability for web-based interfaces.
