A concise, design-forward presentation describing Trezor Bridge: what it is, why it matters, and how to use it safely. Includes official resources for download, support, and developer integration.
Trezor Bridge is a secure background application that enables communication between your Trezor hardware wallet and web applications running in your browser. It offers a stable, cross-platform channel for transaction signing, device firmware interactions, and passphrase/seed handling without exposing private keys to the web.
Bridge removes friction: users can interact with wallets, sign transactions, and manage accounts without complicated drivers or exposing sensitive seeds to web apps. It’s the critical link that keeps user flows smooth and secure.
Trezor Bridge follows the principle of least privilege: only the minimal, authenticated operations are permitted. Private keys remain on the hardware device and never leave. Bridge acts as a communication proxy — it does not weaken device-level protections such as PIN, passphrase, or device seed encryption.
Developers can integrate Trezor devices into applications using the official libraries documented on the developer portal. Bridge provides the transport layer; high-level libraries handle JSON-RPC, device enumeration, and convenience helpers for common signing flows.
See the Developer Docs and GitHub repositories linked in the quick links section for code samples, API references, and integration guides.
Bridge is recommended for systems where native support is absent; some modern browsers support WebUSB which can bypass Bridge for direct communication, but Bridge offers broader compatibility and reliability.
Always download from the official Trezor site and verify signatures when provided. Check the Security Center for guidance on verifying authenticity and upgrades.
