Trezor Bridge®
Connect Your Trezor to Web Browsers — Securely, smoothly, confidently.
Trezor Bridge is the secure, lightweight bridge that lets your Trezor hardware wallet talk to web browsers. Instead of relying on deprecated browser plugins or awkward drivers, Bridge provides a modern local connection that facilitates safe interactions—signing transactions, managing accounts, and using decentralized apps—while keeping your private keys offline and out of reach.
Why Bridge matters
Hardware wallets protect your crypto by holding private keys offline. Bridge fills the gap between physical device and web software: it translates browser requests into USB or WebUSB messages that Trezor understands, and relays user confirmations back to the browser. The result: fast compatibility without sacrificing airtight security.
Quick setup & installation
Get connected in three easy steps
Step-by-step
1) Download Bridge from the official source. 2) Install the application on Windows, macOS, or Linux; it runs as a small background helper. 3) Plug in your Trezor device and open a Trezor-compatible web wallet (or the official Trezor Suite). Grant the browser permission when prompted.
Best practices
- Always download Bridge from the official Trezor website or verified links.
- Keep Bridge updated — updates can include security hardening and support for new devices.
- Use strong device PINs and back up recovery seeds safely offline.
Security model & privacy
A trusted liaison — not a custodian
How Bridge preserves safety
Bridge never holds your private keys. It only forwards encrypted commands between browser and device. All transaction approvals happen on your Trezor device's secure screen with physical confirmation—ensuring an attacker who controls your computer cannot silently approve transactions. Bridge also minimizes network exposure by communicating locally on the machine where it's installed.
Threat model highlights
- Browser compromise: mitigated because the device must confirm operations physically.
- Man-in-the-middle on the local host: Bridge uses secure channels and device-side confirmations.
- Supply-chain safety: prefer official Bridge installers and verify checksums if provided.
Tips, troubleshooting & conclusion
Make the most of Trezor Bridge
Troubleshooting quick-fixes
If Bridge isn't detected: try reconnecting the USB cable, restarting Bridge, or rebooting your browser. On some systems, Bridge may need explicit permission for WebUSB. If you see a permission prompt in your browser, read it carefully before accepting. For persistent issues, reinstall Bridge from the official site and check for OS-specific notes.
Final thoughts
Trezor Bridge simplifies and secures the essential link between your hardware wallet and the broader web of decentralized apps. It preserves the hardware-first security guarantees of Trezor devices while providing a modern, user-friendly experience. When combined with cautious habits—official downloads, secure backups, and device PINs—Bridge unlocks a powerful, practical way to interact with crypto safely.
