Tiny service. Big security. Bridge for hardware wallet connectivity, encrypted transport, cross-platform support and developer-friendly APIs.
Connection made secure
Trezor Bridge: the reliable link between your Trezor hardware device and the web
Trezor Bridge is the trusted connection layer between your hardware wallet and web applications. Designed for secure & smooth crypto access, Trezor Bridge enables seamless communication between desktop and browser-based wallets, exchanges, and DApps while keeping private keys isolated on your device. Whether you are sending funds, signing transactions, managing accounts, or accessing decentralized applications, Trezor Bridge ensures reliable connectivity with minimal setup.
Security-first tunnel
A secure local tunnel ensures only authenticated apps can request signing and account information. All signing happens on-device — private keys never leave the Trezor.
Cross-platform
Windows, macOS and Linux native installers with automatic updates and checks for compatibility with modern browsers and desktop apps.
Developer friendly
Simple, well-documented APIs for DApps and integrations. Sample code, SDKs, and clear error codes speed up safe implementations.
Diagnostics & tools
Built-in logs, reconnection helpers, and device management utilities to help users and support teams troubleshoot quickly.
How Trezor Bridge works
Trezor Bridge functions as a minimal, secure relay: it detects your Trezor device over USB, establishes authenticated sessions with browser or desktop apps, and ensures all requests for signatures are approved on the device. The Bridge does not store or transmit seed phrases or private keys; it simply forwards encrypted requests and returns signed responses. This separation keeps private keys isolated and reduces the attack surface while enabling the convenience of web-based crypto apps.
Features, security recommendations, and advanced usage
Trezor Bridge provides secure local tunneling, encrypted communication, automatic updates and support for multiple devices. For advanced or enterprise setups use centralized logging, per-user policies, and explicit device lifecycle controls. To stay secure: verify downloads, keep Bridge and firmware updated, use air-gapped signing for critical assets, and never disclose your seed phrase. Developers should follow the API docs, use clear prompts for users, and design flows that require explicit on-device confirmation for every critical action.
FAQ
Is Trezor Bridge free to use?
Yes. Trezor Bridge is distributed as a free utility to enable secure connectivity between Trezor hardware wallets and compatible apps.
Does Bridge ever touch my seed?
No. Bridge never accesses or stores seed phrases or private keys — all cryptographic operations that require secrets occur on the hardware device itself.
Where can I get developer docs?
Developer docs and sample code are available on the official integration pages to assist DApp teams and integrators with safe and predictable Bridge usage.
SEO notes for faster indexing
Use HTTPS hosting, include your page in an XML sitemap, submit to Bing Webmaster Tools, and ensure descriptive metadata and structured data (JSON-LD) are present. Avoid broken redirects and use concise headlines to improve crawlability and user experience.
Updates & community
Trezor Bridge benefits from active community contributions and regular releases. Join official forums, follow release notes, and participate in security audits. Community-driven plugins and developer samples accelerate integration and ensure the Bridge remains compatible with the evolving crypto ecosystem.
Conclusion: Install Trezor Bridge to enable secure & smooth crypto access between your Trezor hardware wallet and the apps you trust. Keep software updated, verify official downloads, and always approve transactions directly on your device for the highest level of safety.
