What is Trezor Bridge?

Trezor Bridge is the lightweight connection layer that lets your computer or browser securely communicate with a Trezor hardware wallet when using Trezor Suite and supported web apps. Think of Trezor Bridge as the secure bridge between your offline keys and the online tools you trust — enabling secure cryptocurrency management, transaction signing, and safe Web3 access.

Why Install Trezor Bridge?

Installing Trezor Bridge ensures stable, private, and authenticated communication between your device and the Suite or browser-based dApps. Without Bridge, web-based connections may fail or require additional permissions. Use Trezor Bridge to get the full Trezor Suite experience: manage accounts, send & receive crypto, swap tokens, stake, and review signatures on-device.

1

Download from official source

Always download Trezor Bridge from the official Trezor domain or trusted distribution channels. Avoid third-party mirrors to reduce supply-chain risks.

2

Install and allow permissions

Run the installer for your OS (Windows/macOS/Linux). Follow the prompts and allow the minimal permissions Bridge requests — it only facilitates local USB communication.

3

Open Trezor Suite or connect dApp

After installation, open Trezor Suite or a supported dApp. Bridge runs in the background and enables secure device detection and signing without exposing your keys.

4

Approve transactions on-device

Always verify every transaction on your Trezor hardware screen. Bridge simply transports the request — approval and private key operations happen on-device only.

How Trezor Bridge Works (Simple)

Trezor Bridge listens locally on your machine for secure requests from Trezor Suite or compatible web apps. When a transaction or signature is requested, Suite packages it and sends it through the Bridge to your connected device. The hardware device shows the details, you review, and then sign locally. Signed data travels back through Bridge to the app — at no point does your private key leave the device.

Key point: Trezor Bridge facilitates local connectivity only. All cryptographic operations and key custody stay on the Trezor hardware wallet — keeping your crypto security strong.

Security & Privacy

Trezor Bridge is designed with privacy in mind. It communicates only with local endpoints on your computer and does not transmit or store your recovery seed, PIN, or private keys. To maximize safety: install Bridge from official sources, keep it updated, and always verify the firmware version on your Trezor device before signing critical transactions.

Troubleshooting & Tips

A

Device not detected?

Check USB cables and ports, allow the Bridge process in system security prompts, and restart Trezor Suite. Try a different USB cable if detection fails.

B

Bridge update required

If Suite prompts to update Bridge, accept the update. Updated Bridge versions improve compatibility and security with the latest OS changes.

C

Browser integration

Some browsers may require enabling WebUSB or using the Trezor Bridge helper. Follow the official guidance for browser compatibility and secure connections to dApps.

FAQ

Is Trezor Bridge safe? Yes — Bridge only facilitates local communication. All signing and key operations happen on your hardware device.

Do I need Bridge for Trezor Suite? Bridge simplifies and stabilizes connections for some platforms; Suite may include native connectors on some OS versions, but Bridge remains the recommended local bridge for broad compatibility.
