A concise presentation describing what Trezor Bridge does, why it matters, and how to deploy it securely for everyday crypto custody.
Trezor Bridge is a lightweight local application that securely mediates communications between a web browser or desktop app and your Trezor hardware wallet. It replaces legacy browser plugins and provides a robust, cross-platform transport layer so users can sign transactions, manage accounts, and update firmware with minimal friction.
Trezor Bridge runs on the user’s machine and listens on a localhost port. When a web app wants to use a Trezor device, it sends a request that Bridge safely forwards to the device over USB or WebUSB. The hardware wallet continues to enforce its own secure UI — PIN entry and confirmation happen on the device itself.
Bridge intentionally minimizes privileges: it does not store keys or passphrases, it only routes messages. All sensitive operations are confirmed on the Trezor device, preserving strong physical security guarantees.
Always download Trezor Bridge from trusted and verifiable official pages. Verify checksums when provided and avoid third-party mirrors.
Regularly update Bridge and Trezor firmware. Updates include security fixes and interoperability improvements.
Run Bridge on a trusted machine, avoid installing unnecessary browser extensions, and follow operating system security hygiene (automatic updates, antivirus where appropriate, disk encryption).
