Trezor Bridge
Secure & smooth connection for your crypto wallet

Trezor Bridge — Secure Connection for Your Crypto Wallet

Trezor Bridge is a small, trusted application that runs on your computer and creates a secure, encrypted channel between Trezor Suite (or compatible web apps) and your Trezor hardware wallet. It smooths out browser and OS quirks, improves device detection, and keeps private keys firmly on the device while letting you approve actions with confidence.

Reliable Device Detection

Bridge avoids inconsistent browser USB behavior and ensures your Trezor is recognized across Chrome, Edge, Firefox and other supported browsers.

Local & Encrypted

All communication happens locally on your machine over encrypted channels. Bridge never sends your keys or seed to remote servers — signing is performed on-device only.

Signed Releases

Official Bridge packages are digitally signed. Verify checksums and signatures before installing to ensure authenticity and protect against tampered downloads.

How It Works — Simple Flow

Install Bridge, plug in your Trezor, open Trezor Suite or a supported Web3 app. The app talks to Bridge, which acts as the local messenger to your device. The device shows the action, you verify on-device, and Bridge returns the signed response back to the app — all without exposing your private keys.

Quick Install

Choose the installer for Windows, macOS, or Linux from the official site. Run the installer, accept system prompts, and let Bridge run in the background. On first connection grant the browser permission to communicate with Bridge when prompted.

Troubleshooting Tips

If your Trezor isn’t detected: try a different USB cable or port, restart Bridge, reboot your machine, and avoid USB hubs while troubleshooting. Ensure your device firmware and Bridge are up to date.

Developer Integration

Developers can integrate Bridge into native or web workflows using official APIs. Always point users to signed releases and recommend verification steps before they install any software that interfaces with wallets.

Security — What to Know

  • Private keys never leave the device. Bridge relays requests only; signing occurs inside Trezor hardware.
  • Verify signed installers. Check checksums and signatures from the official Trezor download page before installing.
  • Confirm everything on-device. Always verify addresses, amounts and origin on your Trezor screen before approving.
  • Local-first design. Bridge does not forward private data to remote servers.
  • Minimal privileges. Bridge only requests the permissions necessary to communicate with the device.
  • Open source & auditable. Community review increases transparency and security confidence.
