Trezor Bridge — Secure Your Hardware Wallet®

What is Trezor Bridge?

Trezor Bridge is a lightweight background service that enables secure communication between your Trezor hardware wallet and desktop browsers or applications. It acts as a local proxy, translating browser requests into encrypted USB commands that your device understands. This ensures your private keys remain offline and protected during every transaction.

Why Trezor Bridge Matters

Without Trezor Bridge, your browser may fail to detect your connected wallet, leading to authorization errors or unresponsive interfaces. Bridge eliminates these issues by providing a consistent, secure communication layer across Chrome, Firefox, Edge, and Linux environments. It’s essential for advanced workflows like multisig wallets, third-party integrations, and Trezor Suite compatibility.

Installation and Setup

To install Trezor Bridge, visit the official download page at trezor.io/start. Follow the guided steps to connect your device, verify firmware, and initialize your wallet. Bridge runs automatically after installation and requires no manual configuration.

Security Architecture

Trezor Bridge avoids browser-level APIs that may be inconsistent or insecure. Instead, it uses a controlled local endpoint to prevent unauthorized access and protect against phishing, malware, and man-in-the-middle attacks. All cryptographic operations are performed on the hardware device, ensuring your private keys never leave the wallet.

Compatibility and Integration

Trezor Bridge supports integration with Trezor Suite, Electrum, MetaMask, and other wallet applications. It provides a reliable communication layer for developers building secure crypto tools and supports WebUSB fallback for environments lacking native USB support.
