Trezor Bridge is a small background connector that enables safe, local communication between your physical Trezor device and the Trezor Suite desktop application. It never sends private keys over the internet and acts only as a transport layer for encrypted commands and responses.
Why it matters: modern hardware wallets intentionally separate private key storage from the internet. The bridge allows your browser or desktop app to detect and talk to the device without opening a network-facing API. When installed correctly and kept up to date, it reduces friction and keeps interactions predictable and auditable.
Fresh theme & layout notes
This page uses a light ocean-inspired theme with teal-blue accents and generous white space to communicate clarity and trust. The layout places the how-to and security guidance at the center, with quick actions and support on the right. Typography is slightly condensed for dense technical content while remaining legible on phone screens.
Quick setup (overview)
- Download the official Trezor Bridge from the vendor site (verify the domain and checksum).
- Install and allow the background service (macOS/Windows/Linux prompts may appear).
- Open Trezor Suite — the suite will auto-detect the installed bridge and your device when plugged in.
- Follow the on-device PIN and passphrase prompts; never enter seed words into your computer.
Security reminders
Only install Bridge from official sources. Keep Bridge and Suite updated. Use the device's screen to confirm every transaction, check addresses visually, and enable firmware verification. If you suspect tampering, disconnect immediately and verify firmware via Trezor Suite's verify flow.
