Trezor Bridge — Secure Browser Connectivity
Bridge provides a trusted local connection between your browser and Trezor hardware wallet — enabling safe transaction signing without exposing private keys.
What it does
Trezor Bridge runs on your computer and translates web requests into device-compatible commands. When a wallet requests a signature, Bridge passes the request to your Trezor — but the final approval always happens on the device screen, protecting your keys from remote threats.
🔒
Hardware-backed security
Private keys stay on the device; signing requires physical button press.
⚙️
Seamless browser support
Compatible with Chrome, Edge, Brave, and Firefox via Bridge APIs or WebUSB.
🌍
Cross-platform
Install on Windows, macOS and major Linux distributions.
Why use Bridge?
- Enables web-based wallets and dApps while keeping private keys offline.
- Prevents remote signing — every action must be confirmed on-device.
- Small, background app with automatic compatibility checks.
Security checklist
Make Bridge part of a secure workflow — follow these easy steps:
- Only download Bridge from
trezor.ioand verify file checksums when available. - Keep device firmware and Bridge updated for latest fixes and compatibility.
- Never type or store your recovery seed on a computer or browser.
- Consider using an additional passphrase for extra account isolation (store it securely).
