Trezor Bridge Download — official connector for Trezor devices
The Trezor Bridge Download provides a verified, lightweight background service that enables communication between your desktop (or browser) and a connected Trezor hardware wallet. Use only the official source at trezor.io/start for downloads and verification.
What is "Trezor Bridge"?
Trezor Bridge is a small local service that acts as a secure channel between your Trezor hardware wallet and desktop applications such as Trezor Suite. It enables device detection, account discovery, signing requests, and reliable USB communication in a cross-platform way. Importantly, Bridge does not store or transmit private keys — signing happens exclusively on the hardware device.
The recommended and safest way to obtain Bridge is to perform a Trezor Bridge Download from the official Trezor start page. Using verified installers prevents tampered packages and ensures you receive the latest security fixes and compatibility patches.
Install Guide — step by step
Follow these steps carefully for a correct Trezor Bridge Download and installation:
- Visit the official page: Open trezor.io/start and choose the Trezor Bridge installer for your OS.
- Download verified installer: Prefer the signed installer and, when available, verify the digital signature or checksum as instructed on the site.
- Run installer: Execute the installer (Windows .exe, macOS .dmg, or Linux package/AppImage). Accept any system prompts required for installation.
- Allow permissions: On macOS you may need to approve the app in System Preferences → Security & Privacy. On Linux ensure USB udev rules are configured.
- Restart Bridge or system: If your device is not detected immediately, restarting the Bridge service or rebooting your system often resolves detection issues.
After installation, open Trezor Suite to confirm the device is recognized. Trezor Suite will interact with Bridge to show accounts and request signatures.
Usage & typical flows
Once you have completed the Trezor Bridge Download and installed it, supported applications use Bridge to: detect your Trezor, enumerate accounts, construct unsigned transactions, and forward signing requests. The device itself remains authoritative — every sensitive action must be confirmed on the Trezor screen.
Developers integrating with Trezor Bridge should use the official SDKs and call patterns. Bridge listens on localhost and only responds to authorized applications; do not try to circumvent device confirmation prompts or bypass device-based checks.
Security considerations
Although Bridge does not hold your private keys, treat the Bridge installation as part of your security perimeter. Recommended practices:
- Always download Bridge via the official trezor.io/start page.
- Verify signatures or checksums when provided to ensure authenticity of installers.
- Keep Bridge and Trezor Suite up to date for security patches.
- Limit unknown software that may try to access localhost endpoints; prefer official apps only.
- If you suspect a compromise, reinstall Bridge from the official page and review your system for malware.
By following official guidance for your Trezor Bridge Download, you minimize risk and ensure the communication layer between your computer and hardware wallet is trustworthy.
Troubleshooting
If your Trezor is not recognized after installing Bridge, try the following:
- Reconnect the device and try a different USB cable or USB port.
- Restart the Bridge service (or reboot the computer).
- Check firewall/antivirus settings that might block localhost connections.
- On Linux, ensure udev rules are installed and permissions for USB devices are correct.
- Open Trezor Suite (installed from trezor.io/start) to view diagnostics and logs.
If issues persist, consult the official support links on the Trezor start page or community resources linked from trezor.io/start.
