Trezor Bridge — Overview
Trezor Bridge is the secure, lightweight connection layer that links your Trezor hardware wallet to your web browser, enabling safe and seamless interaction with decentralized applications and cryptocurrency services. Built with privacy and simplicity in mind, Bridge acts as a local communication proxy so that your device never exposes private keys to the internet — all sensitive operations happen offline on your Trezor device. Designed for everyday users and power traders alike, Trezor Bridge supports a wide range of browsers and operating systems, making it easy to manage multiple cryptocurrencies across exchanges, wallets, and DeFi platforms. Installation is straightforward: Bridge runs locally on your machine and automatically handles the encrypted transport of commands between the browser and the Trezor device. There’s no cloud storage, no centralized key repository, and no hidden telemetry — just a direct, auditable link between your browser and your hardware. Security is the heart of the Bridge experience. By compartmentalizing browser interactions from the device itself, Bridge reduces attack surface while preserving convenience. When you request a transaction, the browser sends a prepared request to Bridge which forwards it to the Trezor device. You verify details on the device’s screen and physically confirm actions using the device buttons. Because private keys never leave the Trezor hardware, remote attackers and malicious web pages cannot extract or sign on behalf of your wallet. Bridge also prioritizes developer friendliness. It exposes a simple, well-documented API that web developers can use to integrate hardware-backed signing into their apps. This encourages a healthier ecosystem of extensions, wallets, and services that can natively support hardware security. For end users, that translates into broader app compatibility and a smoother onboarding experience across platforms. Privacy-conscious users will appreciate how Bridge minimizes metadata leakage and keeps interactions local. The software requires minimal permissions and runs only while communicating with your device. Updates are delivered transparently and signed, ensuring you always receive authentic fixes and improvements without compromising device integrity. Performance and stability are core design goals. Bridge operates efficiently in the background, using minimal resources while providing fast, reliable communication. Its auto-detection features recognize connected Trezor devices instantly and surface them to compatible web apps. Troubleshooting tools and clear diagnostic messages make resolving issues quick and intuitive for both novice and advanced users. From casual holders to institutional operators, Trezor Bridge empowers secure crypto ownership by bridging hardware-backed security with modern web convenience. Whether you’re checking balances, signing trades, interacting with smart contracts, or authorizing cross-platform transfers, Bridge keeps the private keys where they belong — safe on your device — while letting you engage with the crypto world confidently and conveniently. Trezor Bridge is maintained with an open-source philosophy: the community and security researchers can audit the code, propose improvements, and verify that the connection behaves as documented. This transparency builds trust for users who demand verifiable security. Supported by comprehensive documentation and responsive support channels, Bridge reduces friction so users focus on managing assets rather than chasing connectivity problems. Always stay protected.
