Trezor Bridge — Connect Your Trezor Wallet Securely

Trezor Bridge is a small, trusted helper that enables secure, encrypted communication between your Trezor hardware wallet and desktop/web applications (like Trezor Suite or compatible Web3 apps). It runs locally, avoids direct browser USB quirks, and provides a smooth, dependable connection so you can sign transactions, manage accounts, and interact with decentralized apps with confidence.

Local & Encrypted

Bridge runs on your computer and uses encrypted channels to exchange messages with your Trezor device — nothing is relayed through external servers.

Browser Compatibility

Avoids browser USB limitations and ensures consistent detection across Chrome, Firefox, and other supported browsers.

Trusted Verification

Bridge is distributed with signed releases so you can verify authenticity before installing — an important step in a secure setup.

How Trezor Bridge Works — Simple

1) Install Bridge on your computer. 2) Plug your Trezor device in. 3) Open Trezor Suite or a compatible app — the app talks to Bridge, Bridge talks to your device, and your private keys stay on the hardware. Approvals are always confirmed on the device.

Quick Install

Download the installer for Windows, macOS, or Linux. Run the installer, accept the prompts, and Bridge starts automatically in the background. When you connect your Trezor the first time, grant the browser permission and follow on-screen instructions.

Troubleshooting Tips

If your device isn’t detected: try a different USB cable/port, restart Bridge (or your computer), ensure firmware is up-to-date, and check your browser permissions. Avoid USB hubs while troubleshooting.

Integration for Developers

Developers can use the Bridge protocol for secure device access in native apps or web integrations. Use official documentation and verify releases before integrating.

Security — Why Bridge is Safe

Private keys never leave the device. Bridge only relays requests; all signing happens on-chain by your Trezor.
Signed releases. Verify checksums and signatures before installation to ensure authenticity.
Local-only communication. Bridge does not forward private data to remote servers.

On-device confirmations. Always verify addresses and amounts on your Trezor screen.
Minimal privileges. Bridge requests only necessary permissions and runs with limited scope.
Open-source transparency. Review code and community audits for extra assurance.
