Seamless and Secure Communication Between Your Computer and Trezor Hardware Wallet
Trezor Bridge is a small software application developed by SatoshiLabs that acts as a communication layer between your Trezor hardware wallet and your computer or browser. It enables web applications, such as the Trezor Suite or third-party crypto wallets, to securely interact with the physical Trezor device.
Traditional browsers do not have native support to communicate directly with hardware wallets via USB. Trezor Bridge fills this gap by facilitating a secure, encrypted connection that allows your browser to send commands and receive responses from your hardware wallet without compromising security.
When you use a Trezor hardware wallet, your private keys never leave the device, which ensures maximum security. However, for you to manage your crypto assets using desktop apps or web wallets, the computer and browser need a way to talk to the Trezor device. This is where Trezor Bridge comes in.
Trezor Bridge runs locally on your computer as a background service. When you connect your Trezor device and open a supported web application, the application communicates with Trezor Bridge using a local HTTP API. The Bridge then forwards these requests over USB to the device.
For example, if you want to sign a Bitcoin transaction, your wallet software sends the transaction data to Trezor Bridge. The Bridge transmits this to the hardware wallet, which prompts you to confirm the details on the device screen. Once confirmed, the signed transaction is sent back through the Bridge to the wallet app, ready to broadcast to the blockchain.
To use your Trezor wallet with a desktop browser or Trezor Suite, you need to install Trezor Bridge first. Here’s how:
Note: Some Trezor Suite versions bundle Trezor Bridge internally, so a separate install may not be necessary.
Trezor Bridge is designed to work seamlessly on:
Supported browsers include:
Browsers must have WebUSB or allow native USB access for Trezor Bridge to function properly.
Although Trezor Bridge is designed to work smoothly, users may occasionally encounter issues. Here are common problems and how to resolve them:

Security is paramount for Trezor Bridge. It acts only as a messenger, never storing or exposing your private keys. All sensitive operations are confirmed on the device itself, preventing phishing or malware attacks from stealing your funds.
Additionally, Trezor Bridge only listens on your local machine and does not send your data over the internet. It uses encrypted communication channels and requires explicit user confirmation on the device for all actions.
Your privacy is preserved because no personal information or wallet details are stored outside your device unless you explicitly share them.
Most desktop browsers require Trezor Bridge for USB communication. However, Trezor Suite bundles Bridge internally, so if you use the Suite desktop app, separate installation may not be necessary.
Yes. It is developed by the Trezor team and open-source. It only facilitates communication between your computer and device without exposing sensitive keys.
Currently, Trezor Bridge is intended for desktop operating systems. Mobile use requires other methods or apps supporting hardware wallets.
Trezor Bridge can manage multiple devices connected one at a time. When you connect a device, the software will prompt you to select which to use if multiple are present.
