Understanding the technology that keeps your crypto safe
Download and install Trézór Bridge on your computer. The lightweight application runs silently in the background, ready to establish secure connections when needed.
Plug in your Trezor hardware wallet via USB. The Bridge automatically detects your device and establishes a secure, encrypted communication channel.
Access your crypto portfolio through your browser. All transactions require physical confirmation on your Trezor device for maximum security.
Trézór Bridge operates as a localhost server (127.0.0.1) on your computer, creating an isolated communication environment between your browser and your Trezor hardware wallet. This architecture ensures that no external party can intercept or manipulate the data flow between your device and web applications.
The Bridge uses WebUSB and HTTP protocols to facilitate real-time communication. When a web application needs to interact with your Trezor device, it sends requests to the Bridge, which then translates these requests into commands your hardware wallet can understand. This translation happens entirely on your local machine, maintaining the zero-trust security model.
Every transaction initiated through the Bridge requires explicit physical confirmation on your Trezor device. This means even if malware compromised your computer, attackers couldn't steal your funds without physical access to your hardware wallet. The Bridge also implements certificate pinning and signature verification to prevent man-in-the-middle attacks.
Regular automatic updates ensure you're always protected against newly discovered vulnerabilities. The update mechanism is cryptographically signed and verified before installation, preventing malicious actors from distributing fake updates. Our development team works closely with security researchers worldwide to maintain the highest standards of protection.
Built with security as the foundation, not an afterthought
All communication between your device and the Bridge is encrypted using industry-standard protocols.
The Bridge doesn't store any private keys, passwords, or transaction history on your computer.
Independent security firms regularly audit our code to identify and fix potential vulnerabilities.
Every transaction must be physically approved on your Trezor device, preventing remote attacks.
Runs in a sandboxed environment, isolated from other applications on your system.
Trézór Bridge is designed to work exclusively with genuine Trezor hardware wallets. Beware of phishing attempts and fake websites. Always verify you're on the official domain and check for HTTPS certification. The Trezor team will never ask for your recovery seed, PIN, or private keys. If you encounter any suspicious activity, immediately disconnect your device and contact official support channels.
Available for all major operating systems
Windows 10 or later (64-bit)
