Keys stay with you
Bridge relays communication; it does not expose your private keys. Confirm addresses and transactions on your physical device, where approvals belong.
01 YOUR WALLET, CONNECTED
A small bridge.
A stronger connection.
Trezor Bridge helps your browser communicate with your Trezor hardware wallet. Here’s what it does, when you need it, and how to get connected with confidence.
Your private keys stay on your device.

•••01 / A SIMPLE EXPLAINER
01 — THE BASICS
What is Trezor Bridge?
Trezor Bridge is a background communication service that lets compatible web applications talk to your Trezor hardware wallet through your computer. Think of it as a secure courier: it carries requests between your browser and your device, while the keys that control your cryptocurrency remain protected inside the wallet.
When you connect through a supported wallet interface, the app may need to ask your Trezor to show an address, check a balance, or prepare a transaction. Bridge helps pass those requests to your device and return the response. You review and confirm sensitive actions directly on the Trezor itself—your private keys are not sent to the browser or stored by Bridge.
Bridge is not a wallet, exchange, or cryptocurrency storage service. It does not hold funds, create recovery backups, or replace your Trezor device. It is simply one part of the connection between your hardware and compatible software.
02 — WHY IT MATTERS
Designed to stay
in the background.
The connection should be the least complicated part of managing your assets.
Browser to device
It provides a communication path for supported browser-based wallet apps, helping them detect and interact with your connected Trezor.
02Simple to maintain
Keeping Bridge and your browser current can resolve compatibility issues. Install only from Trezor’s official site, and follow the setup prompts there.
0303 — GET CONNECTED
Set up in
a few steps.
Use the official Trezor website as your source for downloads and instructions. The exact steps can vary with your operating system and wallet app.
Start at the official source
Visit Trezor Suite or Trezor’s support pages. Check that the address is trezor.io before downloading anything.
Install or update Bridge if prompted
Follow the instructions for your computer. If Bridge is already installed, check the official guidance for the current version rather than downloading from a third-party site.
Reconnect your Trezor
Connect the device directly to your computer with a working USB cable, unlock it, and allow your browser to access the device when asked.
Verify on the device
Check details on your Trezor screen before approving. Never enter your recovery seed into a website, chat, or computer prompt to establish a connection.
04 — NEED A HAND?
Not connecting?
Start here.
Most connection issues have a straightforward fix. Work through these checks before trying again.
Visit Trezor LearnCheck the cable and port
Try a data-capable USB cable and another port. Some cables provide power only and cannot carry device data.
Restart the connection
Close wallet tabs, disconnect and reconnect the device, then reopen the official wallet interface.
Review browser access
When requested, grant the browser permission to communicate with your Trezor. Confirm the selected device is yours.
Update through official channels
Check your browser and Bridge version. Download updates only through Trezor’s official website and support documentation.
A SECURITY REMINDER
Learn about recovery seeds Your recovery seed is never a connection fix.
Bridge, a browser, or a support agent should never ask you to type your recovery seed into a computer or share it online. Anyone who gets your seed can take control of your assets. If a page requests it, stop and navigate directly to Trezor’s official website.
