Trezor Bridge® is an essential communication layer that allows your Trezor hardware wallet to securely interact with modern web browsers. It acts as a trusted connection between your physical Trezor device and web-based applications such as Trezor Suite, enabling safe cryptocurrency management without exposing private keys to the internet.
Designed with security, compatibility, and performance in mind, Trezor Bridge ensures seamless browser integration across Windows, macOS, and Linux systems. Whether you are sending crypto, verifying balances, or signing transactions, Trezor Bridge works silently in the background to keep your digital assets protected.
Trezor Bridge® is lightweight software developed by SatoshiLabs to replace browser plugins that are no longer supported by modern browsers. It allows browsers like Chrome, Firefox, Edge, and Brave to detect and communicate with your Trezor hardware wallet securely.
Unlike browser extensions, Trezor Bridge runs locally on your computer. This architecture significantly reduces security risks and ensures that your private keys remain isolated within your Trezor device at all times.
🔐 Important: Trezor Bridge never accesses or stores your private keys. All cryptographic operations are performed directly on your hardware wallet.
As browser technology evolves, traditional USB communication methods have become restricted. Trezor Bridge® solves this problem by providing a secure and reliable bridge between your wallet and browser-based interfaces.
Trezor Bridge establishes a local connection between your computer and Trezor device, preventing external interception and protecting against remote attacks.
Whether you use Windows, macOS, or Linux, Trezor Bridge is optimized to deliver consistent performance across all supported operating systems.
Once installed, Trezor Bridge runs automatically in the background. You don’t need to manually launch it every time you connect your wallet.
Trezor Bridge works perfectly with Trezor Suite, allowing you to manage assets, update firmware, and verify transactions securely.
When you connect your Trezor hardware wallet to your computer via USB, Trezor Bridge detects the device and opens a secure communication channel. Your browser then sends requests to Trezor Bridge, which forwards them safely to your device.
All confirmations—such as transaction approvals—must be physically verified on the Trezor screen, adding an extra layer of protection against phishing and malware.
