Trezor Bridge is the official communication layer that securely connects a hardware Trezor wallet to the Trezor web interface and desktop clients. It runs locally on the user’s computer and provides an encrypted channel between the browser and the device, ensuring that transactions and sensitive interactions are handled safely and privately.
Web browsers restrict direct USB/HID access for security reasons. Trezor Bridge mediates this gap: it exposes a tightly-scoped local service that the browser can talk to, which in turn speaks with the Trezor device. This keeps private keys off the host machine and prevents unwanted remote access.
Trezor Bridge itself is designed as a minimal trusted component. It uses local-origin enforcement and cryptographic session handling so that only authorized browser contexts can request operations. Sensitive actions require confirmation on the hardware screen — a critical line of defense against remote compromise.
Never install Bridge from untrusted sources. Always download from official channels or follow official documentation to verify checksums and signatures when provided.
Installation is straightforward: run the Bridge installer for your OS and grant the necessary system permissions. Bridge will typically auto-update, but offices with controlled environments may wish to deploy a specific, audited version through their software distribution tools.
For enterprises and IT administrators, Bridge can be deployed silently and monitored. Security teams should review release notes and apply formal patch management processes to ensure Bridge versions match organizational compliance standards.
Bridge does not transmit private keys or account secrets anywhere. It only relays signed public requests and responses required to interact with blockchains. Minimal metadata (device model, firmware version) may be accessible locally for debugging, but this should never include private credentials.
Common issues involve USB permissions, firewall rules, or stale Bridge versions. Reinstalling Bridge, restarting the browser, or checking USB cables usually resolve the majority of connectivity problems.
Trezor Bridge is the lightweight, secure bridge between modern browsers and hardware wallets, enabling safe transaction signing while preserving the hardware-first security model. Proper installation, update hygiene, and user education are the pillars of a secure Trezor deployment in any environment.
