## `accountSubscribe` code examples

This example subscribes to changes in a token account.

<Info>
  Note that subscriptions require a WebSocket connection and [WebSocket cat](https://www.npmjs.com/package/wscat) for you to use this method in the console.

  Install WebSocket cat with:

  `npm install -g wscat`
</Info>

<CodeGroup>
  ```shell wscat theme={"system"}
  $ wscat -c YOUR_CHAINSTACK_WEBSOCKET_ENDPOINT
  # Wait for the connection to be established

  Connected (press CTRL+C to quit)

## Use case

The `accountSubscribe` method in Solana is essential for applications that need to monitor account state changes in real-time. Common use cases include:

* Token tracking: Monitor token account balances for changes to update user interfaces instantly
* Program monitoring: Track program-owned accounts to detect state changes in smart contracts
* Wallet integration: Keep wallet balances and account states synchronized with the blockchain
* DeFi applications: Monitor liquidity pools, lending positions, or other DeFi-related accounts
* Gaming: Track in-game asset accounts and player state changes in real-time

By subscribing to account changes, applications can provide responsive user experiences without constantly polling the blockchain for updates. This is particularly useful for applications requiring real-time updates like trading interfaces, gaming platforms, or wallet applications.
