Trezor Bridge is essential software that enables secure communication between your Trezor hardware wallet and supported web applications. Download and install to unlock the full potential of your Trezor device.
Trezor Bridge acts as a secure communication layer between your Trezor hardware wallet and web-based applications, ensuring your private keys never leave the safety of your device.
In today's digital landscape, hardware wallets like Trezor represent the gold standard for cryptocurrency security. However, to interact with decentralized applications, exchanges, and wallet interfaces through your web browser, a secure bridge is needed to maintain the isolation that makes hardware wallets so secure.
Trezor Bridge solves this challenge by creating a secure, encrypted communication channel between your browser and your Trezor device. Unlike browser extensions that can be compromised, Bridge runs as a native application on your computer, providing an additional layer of security that keeps your private keys safely stored on your hardware wallet at all times.
The software operates on a simple yet powerful principle: it translates requests from web applications into commands your Trezor can understand, while ensuring that sensitive cryptographic operations remain exclusively on your hardware device. This architecture means that even if your computer is compromised, your cryptocurrency assets remain protected by the physical security of your Trezor.

For developers and advanced users who want to understand how Bridge works under the hood.
Trezor Bridge operates as a native desktop application that creates a secure HTTP server on localhost port 21325. This design eliminates the need for browser extensions while maintaining the security isolation that makes hardware wallets effective.
The Bridge application implements a RESTful API that web applications can communicate with using standard HTTP requests. All communication is encrypted and authenticated to prevent unauthorized access to your hardware wallet.
Bridge uses a multi-layered security approach. First, it only accepts connections from localhost, preventing remote attacks. Second, each session is authenticated with temporary keys that expire automatically.
The application never stores private keys or sensitive data on your computer. All cryptographic operations are performed on the Trezor device itself, with Bridge acting solely as a secure messenger between your browser and hardware wallet.
