Bridge the gap between your hardware wallet and the digital world — secure, reliable, and easy to use.
Secure Connector
Your Gateway to Safer Crypto
Trezõr® Brïdge® is the official communication tool that allows browsers and desktop apps to talk to your Trezor device. Without exposing keys, it ensures your crypto journey is both convenient and highly protected.
What is Trezõr® Brïdge®?
Bridge is a lightweight background service that enables secure communication between your Trezor hardware wallet and third-party crypto management platforms. Whether you are managing tokens, accessing decentralized applications, or signing blockchain transactions, Bridge makes the connection seamless.
Key Functions
Secure USB/HID communication with your hardware device.
Local-only access via localhost, never exposing private information to the internet.
Cross-platform stability: works across Windows, macOS, and Linux.
Bridge acts as a secure courier: it carries messages but never looks inside the envelope — your hardware wallet holds the keys.
Why You Need Bridge
Modern browsers restrict direct USB access for security reasons. Bridge provides a trusted, standardized method for apps to communicate with your hardware wallet. This ensures compatibility, reliability, and security while keeping your keys offline.
Benefits
Works with major browsers and crypto apps.
No extra configuration once installed.
Lightweight, efficient, and secure.
Security Principles
Your private keys never leave the Trezor hardware wallet. Bridge only transmits signed messages between your device and applications.
Security Layers
On-device verification for every transaction.
Local-only communication — no cloud relay.
Strict separation of host and device environments.
Even if your computer is compromised, your funds remain safe — as long as you verify details on your device screen.
Developer Integration
Bridge is essential for developers creating Web3 dApps and crypto software. By relying on Bridge, apps can securely request signatures, account information, and device status.
Guidelines
Prompt users to install Bridge if missing.
Respect explicit user consent flows.
Provide fallback options for non-Bridge environments.
