# WebSocket Client

#### Overview

The TransferChain SDK provides a **WebSocket Client** interface to enable real-time communication between clients and the TransferChain protocol. This is especially useful for applications that require instant notifications or updates

#### Key Features

* **Real-time updates**: Receive instant events as they occur within the TransferChain system.
* **Secure channel**: All WebSocket communications are end-to-end encrypted using your TransferChain session keys.
* **Lightweight**: The client maintains a persistent connection without the overhead of constant polling.
* **Pluggable**: Easily integrate into frontend apps, background services, or admin dashboards.

#### How It Works

1. **Authenticate** using your TransferChain credentials.
2. **Initialize** the WebSocket client with your session token.
3. **Subscribe** to events (e.g., file received, password accessed).
4. **Listen** for event messages and react in your app.

#### Security

* All events are encrypted and bound to your session.
* No third-party or public broadcast. Only authorized users can listen to relevant events.
* Tamper-proof message verification using TransferChain’s cryptographic signatures.
