What is Trezor Bridge?
Trezor Bridge is a lightweight background application created by SatoshiLabs to ensure your Trezor hardware wallet securely connects to web browsers and desktop wallets.
Serving as an encrypted communication layer, Trezor Bridge establishes a trusted channel between your wallet and supported apps, allowing safe data transfers, transaction signing, and portfolio management.
Unlike browser plugins and extensions, Bridge works natively across Windows, macOS, and Linux, enabling hassle-free crypto management for investors, traders, and advanced users[web:21][web:22][web:24][web:28].

Browser & Platform Compatibility
Trezor Bridge supports most major browsers (Chrome, Firefox, Edge, Brave) without extra plugins. It works with Trezor Model One, Model T, Safe 3, and Safe 5 devices.
Regular updates ensure stability and support for new browser protocols. If you use modern APIs like WebUSB, Trezor Bridge is still recommended for legacy support and compatibility across multiple operating systems[web:22][web:24][web:27][web:28][web:30].
Advanced Security for Crypto
Trezor Bridge utilizes strong encryption protocols for every connection, keeping your private keys and transaction data out of reach from hacks, malware, and leaking browser extensions.
All data requests, commands, and cryptographic operations happen through trusted channels, signed by your Trezor hardware wallet before being transmitted.
This layered security model ensures man-in-the-middle attacks and malicious software cannot compromise your portfolio even during browser-based activities[web:24][web:30][web:28].
