Trezor Bridge* is the essential connection layer that enables safe, reliable, and user-friendly interaction between your Trezor hardware device and the applications you trust. Built to prioritize security without sacrificing usability, Trezor Bridge* makes key operations — from transaction signing to firmware updates — simple and dependable.
Trezor Bridge* sits between your hardware wallet and the software environment running on your computer or browser. It handles device detection, encrypted communication, and session management so that end-users and third-party apps can rely on consistent, secure behavior. The goal is straightforward: let users interact with their hardware wallet comfortably while keeping private keys isolated and protected inside the device.
All messages between the Trezor device and host applications are encrypted and validated. Trezor Bridge* enforces handshake procedures and message integrity checks so malicious software cannot silently interfere with cryptographic operations.
Trezor Bridge* supports major desktop operating systems and plays well with modern browsers and native apps. The installer includes optimized drivers and detection logic designed to minimize friction on Windows, macOS, and Linux.
Automatic device discovery and reliable reconnection reduce the headaches users sometimes face when switching ports or waking devices. Trezor Bridge* keeps sessions predictable and recoverable.
Updates to Trezor Bridge* are versioned and signed. Administrators and end-users can verify releases and rely on update channels that prioritize stability and security.
Trezor Bridge* is deliberately not involved in holding or deriving private keys — it only transports cryptographic requests securely between the app and the hardware. Private keys remain isolated inside the secure element of the device and never leave it. Every sensitive action requires explicit confirmation on the physical hardware, ensuring phishing or remote attacks cannot sign transactions without physical consent.
Designers of the Trezor ecosystem focused on minimizing user friction: clear prompts, deterministic flows, and helpful feedback reduce accidental mistakes. Installation guides walk new users through pairing, firmware validation, and the first transaction. For advanced users, Bridge provides robust logging and diagnostic information without exposing sensitive secrets.
Trezor Bridge* integrates with consumer wallets, custodial tools that support hardware wallets for withdrawals, and developer SDKs for custom integrations. The API is stable and documented, making it straightforward for wallet providers and dApp teams to add hardware-backed signing to their flows.
Organizations that require bulk deployment or controlled update rollouts can adopt Bridge in managed environments. Policies and documentation support administrators in vetting releases, deploying signed installers, and monitoring device fleets for operational integrity.
In a landscape where digital asset security is paramount, Trezor Bridge* reduces complexity while preserving the strongest safety guarantees. It enables a modern, accessible user experience while ensuring the hardware wallet remains the single source of truth for signing and key custody.
