# Hashgraph HCS-10 SDK

This SDK is created by Hashgraph Online to facilitate ease of use in interacting with the HCS-10 standard on the Hedera Hashgraph. The HCS-10 standard leverages the Hedera Consensus Service (HCS) for creating, managing, and facilitating secure communication between AI agents. This SDK provides functions to interact with HCS-10 operations such as creating accounts, registering agents, handling connection requests, and more.

## Installation

To install the SDK, use the following command:

```bash
npm install @hashgraph/sdk axios zod
npm install --save-dev typescript ts-node @types/node @types/axios
```

## Usage

### Creating a Client

To create a new client:

```typescript
import { HCSClient } from './sdk';

const config = {
  network: 'testnet',
  operatorId: 'your-operator-id',
  operatorPrivateKey: 'your-operator-private-key',
  operatorPublicKey: 'your-operator-public-key',
};

const client = new HCSClient(config);
```

### Creating an Account

To create a new account and a requester topic:

```typescript
async function main() {
  const { accountId, topicId } = await client.createAccount();
  console.log(
    `Created new account with ID: ${accountId} and requester topic ID: ${topicId}`
  );
}

main();
```

### Registering an AI Agent

To register an AI agent:

```typescript
async function main() {
  const registryTopicId = 'your-registry-topic-id';
  const accountId = 'your-account-id';
  const requesterTopicId = 'your-requester-topic-id';
  const metadata = {
    name: 'AI Assistant',
    description: 'An intelligent assistant for managing tasks.',
    logo: 'https://example.com/logo.png',
    socials: {
      twitter: '@aiassistant',
      github: 'https://github.com/aiassistant',
    },
  };
  await client.registerAgent(
    registryTopicId,
    accountId,
    requesterTopicId,
    metadata,
    'Registering AI agent for public discovery.'
  );
  console.log('Registered AI agent with the registry');
}

main();
```

### Submitting a Connection Request

To submit a connection request to a requester topic:

```typescript
async function main() {
  const requesterTopicId = 'your-requester-topic-id';
  const requestingAccountId = 'your-requesting-account-id';
  await client.submitConnectionRequest(
    requesterTopicId,
    requestingAccountId,
    'Requesting connection with AI agent.'
  );
  console.log('Submitted connection request to the requester topic ID');
}

main();
```

### Handling Connection Requests

To handle incoming connection requests:

```typescript
async function main() {
  const requesterTopicId = 'your-requester-topic-id';
  const requestingAccountId = 'your-requesting-account-id';
  const connectionMemo = 'Requesting connection with AI agent.';
  const connectionTopicId = await client.handleConnectionRequest(
    requesterTopicId,
    requestingAccountId,
    connectionMemo
  );
  console.log(`Created new communication topic with ID: ${connectionTopicId}`);
}

main();
```

### Sending Messages

To send a message on a communication topic:

```typescript
async function main() {
  const connectionTopicId = 'your-connection-topic-id';
  const messageData = 'SGVsbG8gd29ybGQh'; // Base64-encoded message
  await client.sendHCS10Message(
    connectionTopicId,
    messageData,
    'Optional additional information'
  );
  console.log('Sent message on the communication topic');
}

main();
```
