Trezor Bridge
Secure & Smooth Crypto Access
Presentation overview
This deck (10 slides) explains Trezor Bridge: what it is, why it matters for hardware wallet connectivity, how it protects users, and best practices to ensure secure and seamless interactions between Trezor devices and desktop browsers or applications.
Executive summary
What is Trezor Bridge?
Snapshot
Trezor Bridge is a lightweight communication layer that securely connects Trezor hardware wallets to desktop browsers and native applications. It runs locally, mediates USB connections, and ensures that sensitive cryptographic operations stay on the device while providing a smooth user experience.
Speaker note: Keep to 60–90 seconds. Emphasize both security and user convenience.
Why it matters
Security + UX
Protecting private keys
Trezor Bridge prevents websites and apps from directly accessing private keys or executing operations off-device. Instead, it passes structured requests that the device verifies and signs. This separation reduces attack surface and defends against malware and phishing.
Key points:
- Private keys never leave the Trezor device.
- Bridge reduces compatibility friction across browsers and OS versions.
- It provides a consistent UX for transaction signing.
How it works
Architecture
Connection flow
At a high level: application → Trezor Bridge (local service) → USB → Trezor device. Bridge translates web or app API calls into device requests, tracks sessions, and routes messages so that the host and device communicate reliably without exposing secrets.
Components:
- Host application (web page or native app)
- Trezor Connect library (JS)
- Trezor Bridge (local background process)
- Trezor hardware device
Security features
Built to minimize risk
Defensive measures
Trezor Bridge employs multiple safeguards: signed firmware verification, origin checking for web requests, strict USB request mapping, and minimal privileges for the host process. These design choices make remote compromise of user keys significantly harder.
Additional protections:
- Session authentication and time-limited tokens.
- Clear user confirmation prompts on device for sensitive actions.
- Automatic updates to Bridge for security patches.
Common user flows
Typical interactions
Examples
1) Wallet setup — Bridge facilitates the initial device initialization and backup. 2) Sending funds — the host constructs a transaction and Bridge routes it for device signing. 3) DApp interaction — Bridge enables web-based dApps to request signatures while preserving user verification on-device.
Tip:
Always verify the transaction details displayed on the hardware device screen — not on your computer.
UX & compatibility
Smooth multi-platform support
Bridging browsers & OS
Trezor Bridge runs on Windows, macOS, and Linux. It handles differences between browsers (e.g., when native WebUSB isn't available) so users don't need to install browser-specific drivers. The result: consistent behaviour across environments.
Design considerations:
- Clear installation instructions and minimal prompts.
- Automatic detection of device connection states.
- Localized messages and accessibility support.
Best practices
Security habits and integration tips
For users:
- Download Bridge only from the official Trezor site.
- Keep firmware and Bridge updated regularly.
- Verify addresses on-device before approving.
For developers:
- Use the official Trezor Connect SDK and follow origin-checking guidance.
- Design UX so users can clearly review transaction details on the device.
- Provide helpful fallbacks and error messaging when Bridge isn't installed.
Troubleshooting
Common issues & fixes
Checklist
If the device isn't detected: check USB cable, confirm Bridge is running, verify browser permissions, update Bridge, and reboot if necessary. For advanced diagnostics, logs can be enabled and sent to official support channels while redacting sensitive data.
Support resources:
- Official Trezor documentation
- Community forums & knowledge base
- Contact support with logs (only if requested)

Secure & seamless access
Call to action
Trezor Bridge is a core piece of secure hardware wallet UX — pairing robust security with practical compatibility. Encourage users to install Bridge from official sources, keep firmware current, and always confirm transactions on their Trezor device.
