Trezor Bridge is the critical link between your Trezor hardware wallet and the decentralized apps, crypto exchanges, and blockchain services you use every day. With device-backed cryptography, phishing-resistant logins, and smooth connection flows, it enables security and convenience without compromise.
Use: Connect hardware wallet to browsers & apps
Transports: WebUSB, WebHID, native bridges
Features: Secure login, on-device approval, audit logs
Trezor Bridge acts as a middleware that securely connects your hardware wallet to desktop applications, browser extensions, and Web3 decentralized apps. It ensures that sensitive operations like logins, token transfers, and approvals happen only after explicit on-device confirmation. This prevents malware or compromised browsers from silently hijacking your crypto operations.
Bridge supports all major platforms — Windows, macOS, Linux — and ensures your Trezor connects seamlessly to web and desktop crypto applications.
Every transaction or login request is displayed on your Trezor device screen, requiring physical button confirmation before proceeding.
Bridge uses secure transports like WebUSB and HID protocols to protect the communication between your device and software.
Setting up Trezor Bridge is straightforward. Follow these steps:
Visit the official Trezor website and download the latest Trezor Bridge installer for your operating system.
Run the installer. Bridge will run in the background and automatically detect your connected Trezor device.
Plug in your Trezor via USB. Your browser or crypto app will now communicate securely through the Bridge.
Whenever an app requests access, confirm the details on your device before approval.
Keep Bridge updated to ensure compatibility with new firmware and evolving security standards.
Trezor Bridge enhances crypto security through multiple layers:
// Conceptual flow
challenge = server.createChallenge()
signature = trezor.sign(challenge)
if server.verify(signature):
grantAccess()
Developers can integrate Trezor Bridge with their apps using the Trezor Connect library. It provides APIs to request user confirmations, sign messages, and execute transactions with minimal code.
// Example: Requesting Bitcoin address
import TrezorConnect from 'trezor-connect';
TrezorConnect.getAddress({
path: "m/49'/0'/0'/0/0",
coin: "btc"
}).then(response => {
if (response.success) {
console.log(response.payload.address);
}
});
With Bridge running, the above call will prompt the user to confirm on their device before returning the requested data.
Q: Do I need Bridge for all apps?
A: Many web apps now support WebUSB or WebHID directly, but Bridge ensures compatibility and smooth connections across platforms.
Q: Is Bridge safe?
A: Yes. It does not store private keys; it only acts as a secure communication layer.
Q: What happens if I uninstall Bridge?
A: Your hardware wallet will still function, but certain apps may fail to connect without it.
Trezor Bridge remains a vital component for anyone serious about secure crypto management. It ensures that your hardware wallet integrates smoothly with the rapidly growing ecosystem of crypto apps, while maintaining the highest level of security. For developers, it provides simple APIs and a tested communication layer. For users, it guarantees peace of mind that every approval truly comes from them — not from malicious software.
