Trezor Bridge — The Secure Gateway to Your Hardware Wallet®
Trezor Bridge is a lightweight, trusted connector that allows your desktop and browser software to securely talk to your Trezor hardware wallet. It acts as a local gateway that translates and routes requests between apps you trust and the hardware device that holds your private keys — keeping your secrets where they belong: offline.
Secure Local Communication
Bridge runs on your local machine and never sends private data to the cloud. All interactions are initiated locally, minimizing remote attack surfaces.
Cross-Platform
Available for Windows, macOS, and Linux. The installer is small and runs silently in the background while you use your wallet apps.
Simple Integration
Web apps use standardized APIs and browser extensions to reach Bridge — no vendor lock-in, straightforward developer experience.
User-Centric Design
Clear prompts and device confirmations make sure you are always in control of approvals and transactions.
How it works — at a glance
When an application needs to communicate with your Trezor device, it asks Bridge for a connection. Bridge authenticates the request locally, opens an encrypted channel to the hardware wallet, and relays only the necessary data. Importantly, private keys remain in hardware and never leave the device. Users confirm sensitive actions physically on their Trezor.
Installation & Usage
Install Bridge to enable desktop wallet apps and browser integrations to detect your Trezor. The process is straightforward: download the installer for your system, run it, then reconnect your Trezor. After installation, most supported apps will find your device automatically.
Quick install commands (example)
# macOS (example) brew install --cask trezor-bridge # Linux (example, package may vary) sudo apt install trezor-bridge # Windows # Run downloaded installer and follow the wizard
Note: These commands are illustrative. Always follow the official download and installation instructions provided by your wallet or device vendor.
Security Principles
Trezor Bridge follows well established security principles: separation of privileges, least privilege for API calls, user presence for critical operations, and explicit confirmation for signing transactions. Because Bridge runs locally, it reduces reliance on remote servers and keeps sensitive operations within your control.
Frequently asked questions
Does Bridge ever send my private key anywhere?
No. Your private keys are generated and kept inside your Trezor device. Bridge only forwards requests and responses — the sensitive signing happens on the device and is confirmed by you.
Can I use Bridge with multiple wallets?
Yes. Bridge is designed to act as a general-purpose local connector; multiple compatible desktop or web wallets can use it concurrently as long as they follow the supported protocols.
What if Bridge needs updating?
Keep Bridge updated; installers may check for updates or notify you. Updates typically include bug fixes and security improvements. Review change logs from trusted sources before upgrading in sensitive environments.
Best Practices
- Always download Bridge from an official source and verify the checksum if provided.
- Keep your operating system and browser up to date to reduce exploit risk.
- Use physical device confirmations — never approve unexpected requests on your Trezor.
- Isolate critical systems if you frequently handle large-value transactions.
- Consider hardware wallet firmware updates only from official channels and review release notes.
