Trezõr® Bridge is a lightweight software component that allows seamless communication between your Trezor hardware wallet and modern web browsers. Instead of relying solely on outdated plugins, Trezor Bridge creates a secure channel so your device can interact with Web3 applications, crypto exchanges, and DeFi protocols without exposing sensitive private keys.
In simple terms, it acts as a “translator” between your hardware wallet and the internet, ensuring every transaction request is verified, confirmed, and signed securely. Without Bridge, your Trezor device would have limited connectivity across different platforms.
If you want to connect your hardware wallet to decentralized applications (dApps) or browser-based crypto services, Bridge is essential. While Trezor Suite provides a powerful interface, many Web3 experiences such as NFT marketplaces, DeFi platforms, and staking portals require a bridge to establish real-time communication.
The necessity of Bridge comes from the fact that browsers have tightened restrictions on plugins. This made older methods like the Trezor Chrome extension obsolete. Bridge ensures compatibility with modern standards and keeps your crypto workflow smooth.
Installing Bridge is straightforward:
Once installed, your browser will automatically detect the Bridge when a website or app tries to communicate with your Trezor device.
Yes. Security is the foundation of every Trezor product. The Bridge does not handle or store your private keys. Instead, it simply facilitates encrypted communication between your browser and the hardware device. The cryptographic signing of transactions still happens inside your Trezor device, which means sensitive data never leaves your hardware wallet.
To stay safe, always download the Bridge only from Trezor’s official website. Avoid fake installers or phishing links that can compromise your security.
Trezor Bridge is cross-platform. It supports:
The team regularly updates Bridge to ensure compatibility with operating system updates and new browser requirements.
