Trezor Bridge

What Is Trezor Bridge?

Trezor Bridge is an essential software component that enables a secure, encrypted communication link between your Trezor hardware wallet and your computer or browser. It acts as the intermediary layer, ensuring that your private keys never leave the device, while allowing you to manage your cryptocurrencies with ease.

Whether you're sending Bitcoin, Ethereum, or thousands of other tokens, Trezor Bridge ensures that all interactions with your Trezor device remain safe, verified, and free from remote exposure.

Why You Need Trezor Bridge

Your Trezor hardware wallet is one of the most secure devices available for cryptocurrency storage. However, to interact with it from your computer or browser, you need a secure channel. That’s where Trezor Bridge comes in. Without Bridge installed, your device cannot communicate with web apps or software layers like Trezor Suite or Trezor Wallet.

Encrypted Communication

All messages between your Trezor device and computer are encrypted and authenticated, preventing tampering or interception.

Cross‑Platform Support

Trezor Bridge works seamlessly on Windows, macOS, and Linux—ensuring you can securely connect from any platform.

Device Verification

Trezor Bridge confirms the authenticity of your Trezor device before enabling any communication, protecting against cloned or compromised units.

Easy Installation

The installation is simple and guided. Once Bridge is running, your Trezor is ready to connect with minimal effort.

Open Source & Transparent

Trezor Bridge is open source, allowing full auditability and community trust in its security.

Automatic Updates

Your Bridge is kept up‑to‑date with security patches and improvements to ensure continued safety.

How Trezor Bridge Works

Understanding the flow of communication helps you trust the process more. Here’s a simplified overview:

1. Your application (e.g. Trezor Suite) sends a request to connect to Trezor Bridge.
2. Trezor Bridge relays that request to your Trezor device, over a secure, encrypted channel.
3. Your Trezor device verifies the request on its screen and awaits your manual confirmation.
4. Once confirmed, Bridge facilitates the message exchange, like commands to sign a transaction or fetch a balance.
5. The signed result is sent back via Bridge to your application, and finally broadcast to the blockchain.

At no point does your private key or seed get exposed. All sensitive operations take place on-device, ensuring maximum security.

Security Best Practices

To make the most of Trezor Bridge's security, follow these recommendations:

• Always download Bridge from the official site (trezor.io/bridge).
• Verify checksums or digital signatures before installing any software.
• Keep Bridge and your Trezor device firmware up-to-date with official releases.
• Always verify transaction details **on the device’s screen**, not just the app.
• Use passphrase protection and a strong PIN for added security layers.
• Do not use Bridge on untrusted or public computers.
