»Trezor Bridge® provides a secure local channel between browser apps and your Trezor hardware wallet — it never exposes private keys.

INSTALL
Install Trezor Bridge® (fast)
1)Visit https://trezor.io/start
2)Download → choose OS → verify checksum (if available)
3)Run installer → restart browser
If your OS prompts for permissions (macOS Gatekeeper or Windows UAC), approve only after verifying the download source.
CONNECT
Connect device & usage flow
•Plug Trezor into USB. Open the web app (Trezor Suite or compatible dApp).
•Allow bridge connection when prompted; confirm on-device.
•Operations: address generation, message signing, transaction approval — approval occurs on device screen only.
SECURITY
Security best practices
1)Only download Trezor Bridge® from official site (trezor.io).
2)Confirm every transaction on the physical device screen (address & amount).
3)Never enter or store your recovery seed in any software — offline paper backup only.
4)Keep OS patched; avoid unknown software during signing operations.
TROUBLE
Troubleshooting checklist
A)Device not detected? → Try a data cable / different USB port / reboot host.
B)Bridge not running? → Reinstall Bridge, restart browser, check system processes.
C)Browser errors? → Clear cache, disable interfering extensions, or use a fresh profile.
D)Persistent issues? → Collect logs and contact official support (never share seeds).
DEVELOPER
Integrating with Trezor Bridge®
•Use Trezor Connect / official libraries for safe integration.
•Show exact payload to user; require explicit on-device confirmation for all signing.
•Test WebHID/WebUSB variations and provide fallbacks — Bridge abstracts many browser differences.
PRIVACY
Privacy & data notes
•Bridge operates locally — no private keys leave the device.
•Local logs may exist; scrub sensitive diagnostics before sharing with support.
FAQ
Quick FAQ
Q:Can Bridge be bypassed? — Modern browsers limit direct USB; Bridge provides a safe abstraction.

CHEAT
Quick commands & tips
TipOn Linux: check for bridge process with ps aux | grep trezor
TipOn Windows: check Services & Task Manager for Bridge process and restart if needed.
Important: If a site requests your recovery seed, treat it as an active scam — close the site, disconnect the device, and move funds to a new wallet if you have exposed your seed.
