🔗 Trezor Bridge – Connect Your Trezor Wallet Securely
Seamless communication between desktop apps and your hardware keys 🔑🛡️
Trezor Bridge is the lightweight, secure connector that creates a trusted channel between your Trezor hardware wallet and desktop applications. Designed with privacy and reliability in mind, Bridge ensures your device signs transactions locally while providing a simple installation and a familiar user experience. Whether you’re interacting with portfolio managers, trading platforms, or developer tools, Bridge keeps keys isolated and operations intentional.
What Trezor Bridge does for you
At its core, Bridge acts as a local communication daemon: it enables secure USB or WebUSB connections, translates application requests into device-friendly commands, and surfaces clear prompts for the user to approve on their hardware. Importantly, all signing and secret operations remain within the Trezor device — Bridge only facilitates a secure conversation between the application and your wallet.
Bridge never transmits private keys or seeds — it forwards signed transactions only after you approve them on the device.
Optimized for quick handshake and fast signing flows so you keep momentum during trades or multisig coordination.
Available for Windows, macOS, and Linux — Bridge runs as a background service and integrates with modern browsers and desktop apps.
Clear API surface and examples for application developers who need to integrate Trezor support safely and predictably.
Security & trust model
Bridge is intentionally simple to minimize attack surface. It uses secure local sockets and requires explicit user confirmation for sensitive operations. Attack vectors like remote signing or secret exfiltration are mitigated because the private material never leaves the device. Bridge is open-source and auditable — enabling security teams and independent auditors to validate the code that bridges your desktop environment with protected hardware.
Easy install — fast setup
Installation is quick: download, run the installer for your operating system, and Bridge starts automatically on first run. Applications that support Trezor will detect Bridge and guide you through a safe connection flow. For environments with strict IT controls, Bridge supports managed installation and configuration through standard packaging formats and enterprise deployment tools.
Designed for pros and power users
Power users appreciate Bridge for its predictable, auditable behavior. It supports advanced flows like multisig coordination, batched signing, and developer debugging. For teams, Bridge can be included in internal tooling and CI systems (read-only/device-emulation modes) to simplify testing while preserving the sanctity of real signing operations.
Common use cases
- Securely signing exchange withdrawals or smart contract transactions.
- Connecting desktop portfolio managers and accounting tools to your cold keys.
- Developer integrations for dApp tooling and developer workflows.
- Enterprise testing and staging via device emulation (without sharing secrets).
Troubleshooting & best practices
If your OS prompts for permission, grant access only to apps you trust. Keep Bridge updated — each release includes bug fixes and compatibility improvements. If a connection fails, restart Bridge or replug the device; on modern browsers you may need to enable WebUSB permissions. For corporate setups, verify package signatures and deploy through your standard IT provisioning pipeline.
Privacy & compliance
Bridge operates entirely on the local machine and does not transmit telemetry by default. For organizations needing audit trails, Bridge can be run alongside logging and monitoring tools that record high-level events (connection attempts, handshake times) without exposing sensitive cryptographic material.
FAQ — quick answers
Do I need Bridge to use my Trezor?
For many desktop applications and older browser flows, Bridge is required. Browser-native WebUSB flows may work without Bridge on supported browsers, but Bridge provides broader compatibility and a smoother experience.
Can Bridge access my private keys?
No. Bridge only relays requests and the device performs signing. Confirm every operation on your hardware display before approving.
Is Bridge open-source?
Yes. The source is available for inspection and contributions from the security community are welcome.
