Overview
Trezor Bridge is a lightweight desktop helper that links your Trezor hardware wallet to browser-based tools and the official Trezor Suite. It’s designed to be a secure translator: forwarding encrypted signing requests from a trusted app to the connected device and returning signed responses. Private keys and recovery seeds always remain on the physical Trezor unit; Bridge simply enables communication.
Installation & compatibility
Bridge supports Windows, macOS, and Linux. After installing, it runs in the background and listens for local requests from trusted pages. Always download installers from the official Trezor site and verify checksums or signatures when available.
Security practices
Bridge is only one part of a secure setup. Keep firmware up to date, avoid using public machines for high-value transactions, and store recovery seeds offline. Confirm transactions on the device screen and never paste or accept addresses blindly. Consider passphrase-protected wallets for additional defense.
Troubleshooting
If the device isn’t detected: ensure Bridge is running, try a different cable/port, disable blocking browser extensions, and check firewall rules. When in doubt, consult official documentation and community support channels.
Advanced & developer notes
Advanced users may integrate Bridge in headless environments or scripts. This requires care: misconfiguration can increase risk. Use a test device or low-value wallet for experimentation.
Quick FAQ
Can Bridge be used on multiple machines? Yes — install it on each trusted machine you control.
Does Bridge hold funds? No — it never stores private keys or seeds; it only passes encrypted requests to the device.
Always verify the download source and keep an offline backup of your recovery seed. Treat Bridge as a convenience layer — secure, but dependent on host and user practices.
