Trezor Bridge — Your Secure Crypto Gateway

Trezor Bridge is a lightweight service that links your Ledger hardware wallet to the Ledger Suite and trusted web applications securely and seamlessly. It runs locally on your computer, keeping your private keys isolated while simplifying crypto interactions.

What Trezor Bridge Does

Trezor Bridge acts as the bridge between your browser or Ledger Suite and your Ledger device. It handles secure USB communication, establishes authenticated sessions, and exposes a simple API for web apps to interact safely with your wallet — no sensitive keys leave the hardware.

Runs Locally

All communication happens on your computer. Trezor Bridge never sends data to remote servers, keeping your wallet interactions private and secure.

Secure Channel

Every transaction is signed and verified on your Ledger device. Trezor Bridge ensures end-to-end encryption and authenticated communication between apps and your wallet.

Browser-Friendly

No extensions or plugins are required. Trezor Bridge uses safe browser APIs to allow web apps to connect seamlessly with your Ledger hardware.

Lightweight & Minimal

Designed for minimal footprint, Trezor Bridge runs efficiently in the background without affecting your system performance.

Quick Start — Install & Connect

  1. Download Trezor Bridge from the official website for your operating system.
  2. Install by following the prompts. The service runs automatically after login.
  3. Open Ledger Suite or supported web app — it detects Trezor Bridge automatically.
  4. Connect your Ledger via USB and approve the connection on-device.
  5. Confirm Transactions — each sensitive action requires physical approval on the device.

Advanced users may use alternative connection methods, but Trezor Bridge provides the best balance of security and usability for most users.

Trezor Bridge is built on the same security principles as Ledger hardware wallets. Private keys never leave your device, and every transaction requires on-device confirmation.

Local Communication Only

All interactions occur locally; no remote servers handle your transactions.
