Trezor Bridge — The Secure Gateway to Your Hardware Wallet® 🔐🪙

Reliable, private, and fast: connect your browser to your Trezor device with a single trusted bridge.

Why Trezor Bridge? Trezor Bridge acts as the trusted conduit between your browser and your Hardware Wallet®. It is designed from the ground up to keep your private keys isolated while enabling a frictionless user experience for managing, signing, and verifying cryptocurrency transactions. ✨

Security-first architecture 🔑

The Bridge keeps critical cryptographic operations where they belong—on your hardware device. All signing happens on the device; the Bridge simply facilitates a secured, authenticated channel to exchange messages. End-to-end isolation means your seed phrase and private keys never leave the device. Our approach minimizes attack surface and maximizes auditable behavior for enterprise and personal users alike. 🔐

Seamless usability & compatibility 🚀

Trezor Bridge supports modern browsers and operating systems so you can work from your desktop, laptop, or trusted kiosk without changing how you manage assets. Installation is lightweight and the connection flow is intuitive — plug in your device, authenticate locally, and you're ready to sign. The Bridge is optimized for low latency and high reliability to keep trades, multisig workflows, and day-to-day operations smooth.

Privacy and control

Privacy is baked into every design decision. Trezor Bridge does not transmit usage telemetry, nor does it collect metadata about your accounts. You retain full control over when a device communicates with your browser and what transactions are permitted. Combined with hardware-backed PIN and passphrase protection, the Bridge forms a robust privacy shield for sensitive operations.

        Enterprise-grade integration: The Bridge provides developer-friendly APIs for wallets, custodians, and exchanges that need secure, reproducible connectivity to Hardware Wallets. Integrate with confidence using stable endpoints and clear documentation — enabling compliance and secure key management at scale.
      

Trusted updates and lifecycle management

Trezor Bridge is maintained with a careful release cadence—security patches and compatibility updates are prioritized and signed to ensure authenticity. Organizations can audit releases, validate signatures, and deploy Bridge updates through secure channels while maintaining operational continuity.
