Trezor Bridge® | Securely Connect Your Hardware Wallet

Trezor Bridge® is the trusted communication tool that links your Trezor hardware wallet to your desktop browser, allowing you to securely manage your crypto assets without exposing your private keys. Fast, lightweight, and privacy-first, Trezor Bridge® ensures that your digital assets are always under your control.

What is Trezor Bridge®?

Trezor Bridge is a software interface developed by SatoshiLabs, designed to enable seamless communication between your Trezor hardware wallet and supported browsers such as Chrome, Firefox, and Edge. Unlike browser extensions or third-party apps, Trezor Bridge runs directly on your desktop, minimizing vulnerabilities and increasing control over your crypto experience.

When you plug in your Trezor device, Trezor Bridge takes over to handle secure data transfers, authenticate transactions, and ensure that sensitive information stays offline and encrypted.

Security is the cornerstone of cryptocurrency management. Trezor Bridge eliminates the need for browser extensions or plug-ins that may be outdated, unverified, or prone to attacks.

Here’s why Trezor Bridge is essential:
