Trezor Bridge

Securely connect your Trezor hardware wallet to desktop applications and browsers. Bridge creates a private, encrypted channel between your device and Trezor Suite or compatible apps.

What is Trezor Bridge?

Trezor Bridge is a small, local software helper that enables secure communication between your computer and a Trezor hardware wallet. It is not a cloud service — it runs locally and only facilitates encrypted device pairing and message exchange.

Why Bridge matters

Creates an encrypted, local channel to your hardware wallet.
Enables browser-based apps and desktop clients to detect and talk to your device.
Keeps private keys on the device — Bridge never accesses or stores private keys or recovery seeds.

Install & setup

Download Bridge: Get the official installer for Windows, macOS, or Linux from the trusted download page.
Run installer: Follow on-screen instructions to install Bridge locally. You may need to allow the installer in your OS’s security settings.
Connect your Trezor: Plug in your device — Bridge will make it available to Trezor Suite and supported web apps.
Allow browser access: When a web app requests access, confirm the prompt and verify on your Trezor device if required.
Keep updated: Check for Bridge updates regularly via the app or official site to ensure compatibility and security.

Quick tip: Trezor Bridge runs locally and only while you interact with your device. It does not forward your data to remote servers.

Common tasks Bridge enables

Device discovery and pairing.
Firmware update flow integration.
Transaction signing requests forwarded to the device screen.
Secure passphrase entry via the device when enabled.

Security & privacy

Bridge is designed with safety in mind. Below are the most important privacy and security considerations when using Bridge.

Core guarantees

Local-only — Bridge runs on your computer and does not send device data to remote servers.
Non-custodial — private keys and recovery seeds remain on the Trezor device at all times.
Signed prompts — all transactions and firmware prompts must be verified on the device display.

Security warning:

Only install Bridge from the official Trezor website. Attackers sometimes distribute fake installers — verify the download URL and check file signatures where provided.

Best practices

Download Bridge only from the official site and verify checksums if available.
Keep your operating system and Bridge up to date to receive security fixes.
Only grant browser access when you initiated the action; revoke permissions if unsure.
Never enter your recovery seed into any computer or website — seeds belong offline only.

Troubleshooting

If Bridge cannot detect your device:

Try a different USB cable or port.
Restart Bridge (or your computer) and reconnect the device.
Temporarily disable interfering browser extensions or other wallet helpers.
Reinstall Bridge using the latest installer from the official site.

FAQ

Do I need Bridge to use Trezor Suite?

Bridge simplifies communication between the device and desktop or browser apps. Trezor Suite web apps may use alternative connection methods, but Bridge ensures reliable local detection and compatibility for many workflows.

Is Bridge safe to run on public/shared computers?

Because Bridge runs locally, it can be used on shared machines — but exercise caution: avoid entering seeds on public machines, and uninstall Bridge or remove device permissions after use if you don't trust the environment.

How do I verify the Bridge installer?

Official downloads often include SHA checksums or code signatures. Verify the checksum against the value on the official website before running the installer.
