# Slim Listener

> Off-chain service that monitors blockchain events and forwards FHE operation requests to the computation layer

| Aspect               | Description                                                                                                                                                                                                                              |

| **Type**             | Off-chain event monitoring service                                                                                                                                                                                                       |
| **Function**         | Listens to blockchain events and forwards FHE operation requests to the fheOS server                                                                                                                                                     |
| **Responsibilities** | • Monitors events emitted by the Task Manager contract on the destination chain<br />• Processes incoming requests and forwards them to the fheOS server<br />• Ensures reliable delivery of operation requests to the computation layer |

The Slim Listener acts as the bridge between on-chain events and the off-chain computation layer, ensuring that all FHE operation requests are captured and forwarded for processing.
