🔐 Trezor Bridge — the secure gateway to your hardware wallet

Trezor Bridge provides a stable, local communication channel between your Trezor hardware wallet and the applications you use — from the Trezor Suite desktop app to web-based wallets and dApps. It’s designed to be lightweight, cross-platform, and secure: Bridge never has access to your private keys — signing always happens on-device.

Local-first

Bridge runs on your machine and exposes a localhost API — no external servers mediate the connection.

Cross-platform

Supports Windows, macOS, and Linux with platform-specific installers and package options.

Secure-by-design

Bridge only forwards messages — private keys remain on the Trezor device and signing requires physical approval.

📘 Overview — what Bridge does

Trezor Bridge acts as a translator between applications and your hardware device. Web apps and desktop Suite send commands to Bridge on a localhost port; Bridge communicates with the Trezor over USB, relays responses back, and ensures sensitive operations are confirmed on the device itself.

Enables web wallets to use hardware wallets reliably
Handles platform-specific USB permission quirks
Provides a stable API for apps to talk to devices
Never reads private keys — signing is hardware-only
