Introduction — What is Trezor Bridge®?
Trezor Bridge® is the small software bridge that lets you connect your Trezor to web browsers and use the full functionality of your hardware wallet in browser-based apps. Whether you need to sign transactions, manage accounts, or use web-based decentralized apps, Trezor Bridge provides a secure and modern connection between your Trezor hardware wallet and web browsers like Chrome, Edge, Firefox, and others.
Why Use Trezor Bridge® to Connect Your Trezor to Web Browsers?
Using Trezor Bridge ensures that when you connect your Trezor to web browsers, communication is routed securely, firmware checks are respected, and the device appears reliably to browser-based wallets and services. Trezor Bridge helps web browsers discover your Trezor device, handle USB permissions, and make browser integration seamless — which is essential when connecting a hardware wallet to web-based crypto tools.
Download & Installation — Trezor Bridge Setup
Download the official Trezor Bridge installer
Get the Trezor Bridge installer for your operating system. When connecting your Trezor to web browsers, always use the official Trezor Bridge package and verify downloads from the project's official source.
Install and allow USB access
Run the Trezor Bridge installer and accept the required system permissions. After installation, Trezor Bridge runs in the background and enables web browsers to detect and communicate with your Trezor hardware device securely.
Connect your Trezor and allow the browser
Plug in your Trezor, open your preferred web browser, and when prompted, allow the website to access the device. Trezor Bridge handles the USB communication so browser sites can securely prompt your device for PIN, confirmation, and transaction signing.
Best Practices — Secure Connection When Using Trezor Bridge®
- Always download Trezor Bridge from official sources and verify checksums where available.
- Keep Trezor Bridge up to date — updates often include security, compatibility, and performance improvements.
- When connecting your Trezor to web browsers, confirm the website's authenticity and use HTTPS-only sites.
- Use a dedicated secure computer for large-value operations when possible; avoid public or shared devices when connecting hardware wallets.
Troubleshooting — Common Trezor Bridge Issues & Fixes
If your Trezor does not appear in the browser after installing Trezor Bridge, try these steps:
- Restart your browser and confirm the Trezor Bridge service is running.
- Replug the Trezor device and try a different USB port or cable.
- Temporarily disable conflicting browser extensions that manage USB devices.
- Check firewall or security software that may block local bridge communications.
- Reinstall the latest Trezor Bridge package and restart your system.
Integrations — Use Cases When You Connect Your Trezor to Web Browsers
After you connect your Trezor to web browsers using Trezor Bridge, you can: manage multiple accounts, sign blockchain transactions, use decentralized exchanges (DEXs), interact with decentralized apps (dApps), verify addresses, and confirm multisig workflows. Trezor Bridge is the link that turns your hardware wallet into a browser-friendly security device.
Privacy & Security Considerations
Trezor Bridge is a local bridge — it only facilitates local communication between your machine, your web browser, and the Trezor hardware wallet. When you connect your Trezor to web browsers, private keys never leave the Trezor device, and sensitive actions require you to confirm on-device. Always protect your recovery seed and never enter it into a browser.
