About Trezor Bridge®

Trezor Bridge® is the secure, lightweight connection layer that links your Trezor hardware wallet to web browsers and desktop applications, enabling seamless, reliable interactions with cryptocurrency services. Designed by SatoshiLabs with a focus on security and usability, Trezor Bridge® makes signing transactions, managing accounts, and interacting with decentralized applications straightforward while keeping private keys isolated on your device.

By using Trezor Bridge®, users benefit from an architecture that separates the web interface from critical cryptographic operations. The browser communicates with Bridge over a local, encrypted channel; Bridge in turn communicates with the Trezor device via USB or WebUSB. This separation reduces attack surface, minimizes browser-specific vulnerabilities, and preserves the hardware wallet’s core promise: private keys never leave the device. Whether you are a long-term hodler, an active trader, or a developer integrating hardware support, Bridge provides a predictable, auditable connection model.

Installation is simple and unobtrusive. Bridge runs as a small native application on Windows, macOS, and Linux, automatically updating when necessary and offering a minimal footprint. For users who prefer not to install software, supported browsers and platforms provide alternatives such as WebUSB; for developers, the Trezor Connect API and documentation make it straightforward to add hardware wallet support to web apps while offering clear caveats and best practices.

Security is the cornerstone of Trezor Bridge®. The software is engineered to refuse unsigned or malformed requests, enforce user confirmation on the device for sensitive actions, and log minimal information locally. SatoshiLabs encourages transparency: Bridge updates and release notes are published openly, and the broader community and security researchers regularly audit the codebase. Users are advised to download Bridge only from the official Trezor website and verify signatures when available to avoid supply-chain risks.

Trezor Bridge® also prioritizes user experience. The connection flow is designed to be intuitive: plug in your Trezor, open a compatible website or app, and follow on-screen prompts to confirm addresses and transactions directly on your device. Clear status indicators in Bridge help diagnose connection issues quickly, and comprehensive troubleshooting guides assist users with driver, permission, or browser-related questions.

For organizations and developers, Bridge provides predictable behavior and programmatic interfaces that simplify integration testing and user onboarding. The Trezor ecosystem supports multiple cryptocurrencies and standards, and Bridge continuously evolves to accommodate new chains and features while respecting security boundaries.

Ultimately, Trezor Bridge® exists to make hardware-backed security accessible without compromise. It removes friction from routine tasks while maintaining the strongest possible protections for private keys. By combining thoughtful engineering, transparent practices, and a user-centered approach, Trezor Bridge® helps individuals and teams interact with the open financial stack confidently. For peace of mind and dependable performance, Trezor Bridge® is the trusted link between you and a secure crypto future. Install from the official site, follow guidance, and keep your firmware and Bridge up to date for protection.

How does Trezor Bridge® work?
Bridge runs locally on your machine and exposes a secure channel for browsers or apps to request actions. All signing and confirmations happen on the Trezor device itself, preventing sensitive key material from being exposed to the host system.
Security & privacy considerations
Bridge minimizes stored data, refuses malformed requests, and prompts for device confirmation on sensitive actions. Always download Bridge from the official Trezor domain and verify signatures when provided.
Troubleshooting: device not detected
Common fixes: try different USB ports/cables, confirm browser permissions for WebUSB, restart Bridge, and check OS drivers. For persistent issues consult the official support guides.
