Trezor Bridge โ€” The Secure Gateway to Your Hardware Wallet

Trezor Bridge connects your Trezor hardware wallet to web apps and desktop tools safely. Use Trezor Bridge for secure connections, private key protection, and seamless crypto management.

Why Trezor Bridge matters

In an increasingly online world, protecting private keys is critical. Trezor Bridge acts as the secure gateway that keeps your keys offline while enabling powerful web interfaces and native apps to interact with your hardware wallet. Trezor Bridge ensures communication between your computer and Trezor device is encrypted, authenticated, and limited to necessary operations only. When you search for "Trezor Bridge" online, you'll find it referenced as the safe, reliable layer required for modern hardware wallet workflows.

How Trezor Bridge works

1
Local connection: Trezor Bridge runs locally on your computer, handling USB and WebUSB calls. It exposes a small secure API that authorized apps can use.
2
Encrypted messages: Commands are signed and encrypted between the app and the hardware device, so your seed never leaves the Trezor.
3
Strict approval: Any transaction must be confirmed on the physical Trezor device โ€” this is the last line of defense.

Installation & quick start

Get started in three steps: download - install - connect. Trezor Bridge is available as an installer for major platforms. After install, open your preferred wallet (like Trezor Suite or compatible web apps) and follow the on-screen prompts. When in doubt, always prefer official Trezor sources to download Trezor Bridge for safety.

# Example (macOS brew style - symbolic)
# Visit the official Trezor site for installers. Do not download from unknown sources.

Security best practices

Always verify the origin of the app that requests access to Trezor Bridge. Never share your recovery seed, backup, or PIN. Use a passphrase if you need an extra layer of security. With Trezor Bridge, transactions must be manually confirmed on the device โ€” this prevents remote exploits from emptying your wallet without physical approval.

Compatibility & system requirements

Trezor Bridge supports modern Windows 10+, macOS 10.14+, and common Linux distributions. It integrates with browsers and native apps through a small local daemon. If you are using a Trezor Model T or Trezor One, Trezor Bridge is the recommended connection method for the smoothest experience.

Troubleshooting

If your computer doesn't detect your Trezor device: try reinstalling Trezor Bridge, use a different USB port, avoid USB hubs, and ensure the device is unlocked. Consult official troubleshooting guides and keep Trezor Bridge updated โ€” many connection issues are solved by the latest release.

Developer notes

Developers can integrate Trezor Bridge with standard WebUSB or platform-specific APIs. Follow recommended rate limits and always request the minimum permissions required. Review the project on its official repository for API details and examples.
