Trezor Bridge 2025 | Official App for Secure Wallet Linking

Trezor Bridge 2025 is the official linking application designed to make connecting your Trezor hardware wallet to desktop apps and modern web wallets effortless — without sacrificing privacy or control. It operates locally on your machine, providing a secure channel between hardware and software while keeping secret keys strictly on-device.

Privacy-first local bridge

All communications flow locally between the browser and your device — nothing is stored in the cloud. Trezor Bridge uses end-to-end encrypted channels to ensure your secret keys never leave the device.

Plug-and-play compatibility

Works with major browsers and desktop wallets. Simple installer, zero-configuration for most setups, auto-updates (optional) and robust fallback for restricted environments.

Performance & reliability

Optimized to minimize latency while signing transactions. Persistent connection handling reduces timeouts and improves multi-app workflows.

Compatibility & How it Works

Trezor Bridge acts as a local daemon and communicates with browser extensions or desktop wallets via a secure, authenticated protocol. It exposes a local endpoint that is only reachable from your machine and verifies every signing action with the hardware device itself.

Frequently Asked Questions

1. What is Trezor Bridge and why do I need it?

Bridge is the official connector application that enables secure communication between your Trezor hardware wallet and desktop/web wallets. It creates a local channel so web apps can request signatures from the hardware without exposing keys to the internet.

2. Does Bridge collect any personal data or keys?

No. Bridge only manages local communication and metadata necessary to perform operations. Private keys and seed phrases remain on the Trezor device at all times and are never transmitted to Bridge or any cloud service.

3. How do I verify the installer I downloaded?

We provide SHA256 checksums and PGP signatures alongside each release. Verify the checksum locally and, if desired, confirm the PGP signature using the official Trezor release key. Never install an unknown or tampered binary.

4. What if Bridge doesn't recognize my device?

Common fixes: ensure cable is data-capable (not charge-only), try a different USB port or cable, install the latest drivers for your OS, and reboot Bridge. For stubborn cases, consult logs or use the built-in diagnostics in the app.

5. How can I run Bridge in a restricted or air-gapped environment?

For air-gapped workflows, use the minimal CLI bridge or connect via an approved offline workflow. There are specific builds and documentation for enterprise or high-security setups — reach out to support for tailored guidance.
