Trezor™ Bridgeʬ | Securing℗ Your Digital Assets©

Local bridge service for private, verified hardware wallet interactions

Trusted Local Relay

Bridge the web and desktop experience to your Trezor—safely and privately.

Trezor™ Bridgeʬ is a lightweight local service that enables secure communication between your browser or desktop apps and your Trezor hardware wallet. Designed to minimize attack surface and maximize user control, Bridge ensures transactions and signing requests are relayed locally and only completed after your explicit approval on the device.

Local-first Design

No cloud relays. Bridge runs on your machine and forwards encrypted requests directly to the device, keeping sensitive operations local.

Manual Confirmation

Every signature requires on-device verification. The physical device displays amounts, addresses, and metadata before signing.

Cross-platform

Installers for Windows, macOS, and Linux — small footprint with automatic update options.

Developer APIs

Well-documented local APIs let developers integrate hardware support into wallets and dApps while following security best practices.

How it works — in four steps

  1. An application (web or desktop) requests access to a Trezor device via the local Bridge service.
  2. Bridge verifies the application's origin and relays the encrypted request to the connected Trezor device.
  3. The Trezor device presents the transaction details so you can review and confirm on the device display.
  4. After you confirm, the device signs locally and Bridge returns the signed payload to the application for broadcast.

Bridge is purely a relay and does not store private keys or sign transactions without explicit device approval.

Security and privacy considerations

  • Download Bridge only from official Trezor sources and verify signatures when available.
  • Keep your device firmware current; updates often include critical security patches.
  • Verify every transaction on the device screen to prevent UI-level tampering or address-rewriting attacks.
  • Avoid running Bridge on public or untrusted machines; run it on personal devices under your control.

For developers

Trezor Bridge offers a minimal local API that prioritizes origin verification and explicit user consent. Developers integrating Bridge should request only necessary scopes, implement clear user-facing prompts, and always instruct users to verify transaction details on their Trezor device. Reference SDKs and example integrations are available to shorten your integration path while preserving strong security guarantees.

  • Authenticate and validate the calling origin before forwarding requests.
  • Design flows that minimize repeated prompts and clearly explain device confirmations.
  • Log minimal diagnostic information and avoid transmitting sensitive payloads to remote servers.

Privacy policy snapshot

Bridge is intentionally local-first. It does not collect personal data or forward usage analytics by default. If you choose to enable diagnostic logging for support, review logs carefully before sharing to avoid leaking sensitive information.

Support & resources

For downloads, developer guides, and troubleshooting, consult the official Trezor documentation and support channels. Community forums and knowledge-base articles can also help with common configuration questions.
