Trezor Bridge – Secure Link Between Browser and Hardware Wallet
Trezor Bridge is an official communication service that allows a Trezor hardware wallet to connect safely with supported browser-based wallet interfaces. As modern browsers phase out legacy plugins, Bridge provides a secure and reliable alternative for device interaction without compromising private key protection.
For users managing cryptocurrencies through Trezor, Bridge plays an essential technical and security role.
What Is Trezor Bridge?
Trezor Bridge is a lightweight background application developed by SatoshiLabs. It enables encrypted local communication between your web browser and Trezor hardware wallet.
Instead of relying on browser extensions, Bridge operates as a standalone service within your operating system.
Why Trezor Bridge Is Necessary
Browsers impose strict limitations on direct USB hardware access for security reasons. Trezor Bridge resolves this by acting as a trusted local intermediary.
Without Bridge, users may experience:
- Device detection failures
- Interrupted wallet connections
- Limited browser compatibility
Bridge ensures smooth recognition and secure data exchange.
How Trezor Bridge Protects Users
Security is the primary objective of Bridge.
Private Keys Remain Offline
Sensitive operations never leave the Trezor device.
Encrypted Local Communication
Data transmitted between browser and device stays within your computer.
Elimination of Risky Plugins
Reduces exposure to malicious browser extensions.
Physical Confirmation Required
Transactions must be approved directly on the hardware wallet.
These protections significantly lower the risk of phishing or malware attacks.
How Trezor Bridge Works
Once installed, Bridge runs silently in the background:
- A wallet interface sends a connection request
- Bridge captures the request locally
- The Trezor device receives instructions
- The user confirms sensitive actions
This workflow ensures the browser never directly handles private key operations.
