Trezor Bridge is the lightweight, trust-first bridge that securely links your Trezor hardware wallet to desktop apps and web interfaces. Designed for users who demand maximum control over private keys, Bridge operates locally on your computer — it never uploads seed phrases or private keys to the cloud. The result is a clear separation between your funds and any online exposure: you keep the keys, we provide the trusted conduit.
Trezor Bridge simplifies device communication while preserving advanced security properties. During everyday use, Bridge translates USB and HID communications into an encrypted, authenticated channel for applications such as wallet managers, portfolio tools, or exchange integrations. It’s intentionally small, auditable, and transparent: install the Bridge binary, authorize your device, and the software presents a consistent, dependable API for developers and power users alike.
For individuals and teams that manage multiple devices, Bridge includes features to streamline workflows without compromising safety. It supports device discovery, per-device session handling, and clear user prompts for every transaction signing request. Whether you’re confirming a single small transfer or approving a complex multi-input transaction, the device always displays the details and requires your explicit physical confirmation.
Security is the leading design principle. Bridge is engineered to be resilient against common attack vectors: it minimizes privileged operations, uses secure transport layers on supported platforms, and reduces the attack surface by delegating sensitive operations to the Trezor device itself. Regular updates and open-source code mean the community and security researchers can continuously audit and improve the codebase.
Getting started is straightforward. Download the Bridge installer for macOS, Windows, or Linux, run the installer, and follow the on-screen instructions to pair your Trezor. Advanced users can run Bridge in a headless mode for automation or in restricted network environments. For developers, a small, well-documented API makes integration quick — and for end users, friendly prompts and helpful recovery guides mean fewer worries during setup.
Bridge also supports modern usability improvements: better device name handling, clearer error messages, and compatibility with the latest firmware versions. For anyone migrating from other workflows, Bridge provides compatibility helpers and clear migration documentation to ensure a smooth transition without risking seed exposure.
At its core, Trezor Bridge is about one promise: keep private keys offline and under your control while enabling seamless interaction with the tools you already use. If you care about true ownership, reproducible security, and software that respects user autonomy, Trezor Bridge is built for you.
