Trezor Bridge historically acted as the local communication layer between web browsers and Trezor hardware wallets. It ran on your computer, routed requests safely to the device, and allowed web apps and desktop apps to talk to the Trezor securely without exposing private keys. This presentation summarises what Bridge did, important modern changes, practical steps for users, and links to official resources.
Device discovery & transport: Bridge detected connected Trezor devices and forwarded requests via a secure local channel.
Compatibility shim: It offered a consistent API surface for browsers and the Trezor Suite app, avoiding direct USB handling in web pages.
Security posture: Bridge was intentionally minimal: it only passed messages and relied on Trezor firmware to confirm every transaction on the device itself.
Trezor has announced the deprecation and removal of the standalone Trezor Bridge in favour of integrated functionality inside Trezor Suite and modern, supported channels. If you rely on a standalone Bridge install, follow official guidance to migrate and uninstall the standalone package to avoid future incompatibility.
1. Backup: Ensure your device recovery seed is safely stored before major changes.
2. Install/Update Trezor Suite: Use the official Suite desktop app or web Suite for the newest integrated communication stack.
3. Remove old Bridge: If you have a legacy Bridge installed, uninstall it following the OS-specific instructions from the official guide.
4. Verify downloads: When downloading Suite or bundles, verify signatures where applicable (GPG/Kleopatra instructions exist for advanced users).
5. Ask for help: Use official support channels or community forums when you encounter unexpected prompts or device behaviour.
Keep firmware and software up to date, install official releases only, verify digital signatures for installers if you need the highest assurance, never enter your recovery seed into a computer or browser, and always confirm transactions on the Trezor device screen.
Trezor Bridge once served as the safe local relay for hardware wallet communication. Today, Trezor encourages users to move to integrated solutions like Trezor Suite and to follow official migration instructions. Always use official channels, verify installers if you require the highest security guarantees, and confirm every transaction on-device.
