How Trezor Bridge Works
Trezor Bridge acts as a local intermediary between your Trezor hardware wallet and web or desktop applications. It ensures private keys remain on the device, verifies every transaction on-device, and allows secure communication without sending sensitive data over the internet.
Privacy-first
All communication occurs locally on your machine; Bridge never sends sensitive data to external servers.
Verified signing
The Trezor device displays transaction details and requires user approval for every signing operation.
Cross-platform
Available for Windows, macOS, and Linux with seamless updates and auto-start functionality.
Developer-friendly
APIs enable secure integration for apps and wallets with strict origin verification and minimal exposure.
Developer Guidance
Use local APIs to request operations while maintaining user verification. Best practices include minimal data requests, clear UI prompts, and short-lived sessions.
