How Trezor Bridge provides a secure connection for your Trezor

At its core, Trezor Bridge is a small, trusted program that listens on a private local endpoint and forwards requests between web apps and your Trezor hardware wallet. This arrangement keeps device communication within your machine and avoids browser inconsistencies when using direct USB transports.

The phrase Trezor Bridge — Secure Connection for Your Trezor emphasizes two things: the Bridge is the connection facilitator, and it preserves the security guarantees of the hardware device. When a web application asks for a signature or requests a public key, Bridge ensures that requests are relayed intact and that the device prompts you to approve every sensitive action.

Trezor Bridge does not hold or process private keys. The secure connection is strictly a communication channel: it authenticates devices, allows message framing that web apps expect, and helps developers avoid low-level USB traps that can lead to inconsistent behavior across browsers.

Flow: Web App → Trezor Bridge (local) → USB → Trezor Device → User confirms on device → Signed Data → Bridge → Web App

Installation and safe setup

Always download Trezor Bridge installers from the official website or a verified release page. After installing, confirm that your operating system shows a running Bridge service and that browser prompts explicitly ask for the device. Never approve unexpected signing requests and verify transaction details on the physical Trezor screen before confirming.

Developer friendly

Developers building web wallets or integrations benefit from Bridge’s stable API and consistent device enumeration. Instead of handling multiple browser USB implementations, you can depend on Bridge to provide a uniform transport layer — making development faster with fewer platform-specific edge cases.

Download & quick start

Head to the official downloads page linked from your vendor domain. Choose the correct installer for your operating system, run the installer, and follow on-screen instructions. After installation, connect your Trezor via USB, open a supported web wallet, and you should see the device available for connection.

Important safety checklist

  • Download installers only from official pages and verify checksums when provided.
  • Keep Trezor firmware and Bridge up to date to receive security improvements.
  • Confirm all transaction details on the physical device before authorizing.
  • Use HTTPS-only web apps and avoid unknown pages asking for device access.
