Trezor Bridge runs locally and creates a fast, private connection between your Trezor hardware wallet and web applications. It preserves device-centric security while removing the friction of USB drivers and browser incompatibilities. Install once, connect instantly, and transact with confidence.
Trezor Bridge keeps all sensitive keys on your hardware while enabling modern web UX. It is the recommended local connector when you want usability without compromising security.
Trezor Bridge is a lightweight background process that mediates secure communication between your Trezor device and browser-based or desktop wallet software. Rather than exposing private keys to the host environment, the bridge forwards signed messages and device states only after the user approves each action at the device.
Designed for reliability, the bridge avoids brittleness caused by browser API changes by running as a native helper. This removes the need for fragile plugins and provides a consistent developer and user experience across Windows, macOS, and Linux.
Trezor Bridge focuses on three goals: dependable discovery, encrypted local channels, and minimal host footprint. The bridge accepts device requests from clients and relays them to your hardware after user confirmation, preserving the security model that makes hardware wallets compelling.
Device appears instantly when plugged in — no manual driver juggling.
Local requests are constrained to the machine; communications are authenticated and ephemeral.
Small memory & CPU usage — runs silently in the background.
Keeps compatibility with browser changes and firmware improvements.
Trezor Bridge installs like a trusted desktop helper. Download the signed installer from the official start resource, run it, and after granting standard permissions plug in your device. Your wallet interface should discover the device automatically and request confirmations for actions. If detection fails, a restart or reinstall typically resolves transient USB conflicts.
Always verify downloads via official channels and keep both firmware and bridge versions current for best security and compatibility.
Trezor Bridge intentionally separates duties: it routes requests and responses, but the hardware enforces transaction signatures. The bridge cannot sign transactions on behalf of a user and it cannot extract private keys. This separation ensures that even if the host machine is compromised, private keys remain safe behind the device's secure element.
Follow basic hygiene: verify device prompts, download official installers, keep software updated, and limit bridge installations to trusted machines.
Every sensitive operation requires on-device approval.
Bridge only relays approved actions and status info.
Trezor Bridge removes friction while preserving the highest security guarantees of hardware wallets. For anyone serious about securing crypto but wanting a modern, usable experience, the bridge is the trusted connector. Install, connect, and keep control where it belongs — on your device.
