Trezor Bridge is the lightweight connectivity layer that lets your desktop browser securely talk to your Trezor hardware wallet. Built with privacy-first principles and a focus on simplicity, Bridge creates a trusted channel between your device and the applications you use to manage cryptocurrencies.
Why Trezor Bridge matters
When managing private keys on a hardware wallet, the connection between your computer and device must be robust, private, and transparent. Trezor Bridge ensures that your transactions are signed on-device, your keys never leave the hardware wallet, and communications are minimal and auditable. It supports a seamless experience across operating systems and keeps the UX polished so power users and beginners both feel confident.
Device-only signing, minimal data exchange, and cryptographic verifiability.
Automatic device detection, fast handshakes, and clear prompts for every action.
Works on Windows, macOS, and Linux — install once, connect instantly.
No telemetry, optional logging, and transparent updates.
How it works (simple)
Trezor Bridge installs a small local service that mediates secure JSON-RPC style messages between web apps and your Trezor device. When you use a supported wallet or manager, Bridge negotiates a short-lived session, forwards only the necessary messages, and ensures you confirm every action on the physical device. That means even if your computer is compromised, transaction approval still requires your presence at the Trezor device.
Getting started
Download the installer for your platform and follow the guided setup. After installation, open your preferred wallet interface and follow the on-screen prompts to connect. Always verify device fingerprints shown on both the device screen and the host app to ensure authenticity. For enterprise or advanced setups, Bridge can be deployed with silent install and managed update policies.
Security tips & best practices
Always download Bridge from an official source. Keep your firmware and Bridge versions updated. Use a strong PIN on your device and never share your recovery seed. For added safety, keep a separate, offline machine for large withdrawals and review transaction details carefully before approving them on the Trezor hardware display.
Developer notes
Bridge exposes a clear API for integrators and has a small, documented handshake flow. Developers can test in sandbox environments and use verbose logging during integration. The codebase separates UI integration from low-level transport so wallets can implement custom UX while relying on Bridge for security-sensitive operations.
Accessibility & support
Bridge follows accessibility-minded patterns: keyboard navigable installers, clear high-contrast prompts on the device, and detailed documentation for assistive technologies. If you run into issues, reach out to official support channels for guided troubleshooting and updates.
Commitment to transparency
Trezor Bridge, like other components of the Trezor ecosystem, is designed with open principles — change logs, release notes, and security advisories are published so users can validate the integrity of the software they install. Trust is built through open processes, audits, and clear communication.
