Flow Agent Kit

Flow Agent Kit is a development tool that enables the creation of AI agents that interact with the Flow blockchain.

What is it for?

$3

- Allows AI agents (using LangChain) to directly interact with the Flow blockchain
- Can perform operations such as transfers, balance queries, and smart contract deployment

$3

Using Flow Agent Kit as an NPM package offers several advantages:

1. Easy Installation

- Install with a single command: pnpm add flow-agent-kit
- Automatic dependency management
- No manual repository cloning needed

$3

``typescript
export class FlowAgentKit {
public address: string;
private genAI: GoogleGenerativeAI;
private model: any;

/**
* Creates an instance of FlowAgentKit
* @param private_key - Flow account private key
* @param network - Flow network to connect to
* @param gemini_api_key - Gemini API key for AI features
*/
constructor(private_key: string, network: FlowNetwork = 'mainnet', gemini_api_key: string) {
// Configure FCL
const accessNode =
process.env.FLOW_ACCESS_NODE ||
(network === 'testnet'
? 'https://rest-testnet.onflow.org'
: network === 'mainnet'
? 'https://rest-mainnet.onflow.org'
: 'http://localhost:8888');

const walletDiscovery =
network === 'mainnet'
? 'https://fcl-discovery.onflow.org/authn'
: network === 'testnet'
? 'https://fcl-discovery.onflow.org/testnet/authn'
: 'http://localhost:8701/fcl/authn';

fcl.config({
'flow.network': network,
'app.detail.title': 'Flow Agent Kit',
'accessNode.api': accessNode,
'discovery.wallet': walletDiscovery,
} as any);
}
}
`

$3

After installation, you can use the kit in two ways:

#### Chat Mode

- Interactive command-line interface
- You can chat with the agent and request blockchain operations
- Example: "What's my balance?" or "Transfer 10 FLOW to 0x1234..."

#### Autonomous Mode

- The agent operates independently, executing programmed actions
- Useful for automation and monitoring

$3

`typescript
import { FlowAgentKit } from 'flow-agent-kit';

// Initialize the agent
const agent = new FlowAgentKit('your_private_key', 'mainnet', 'your_gemini_api_key');

// Check balance
const balance = await agent.getBalance();
console.log('Balance:', balance);

// Generate content with AI
const response = await agent.generateContent('What is Flow blockchain?');
console.log('Response:', response);
`

Installation

1. Clone the repository:

`bash
git clone https://github.com/Flow-Brasil/flow-agent-kit.git
`

2. Enter the folder:

`bash
cd flow-agent-kit
`

3. Install dependencies:

`bash
pnpm install
`

4. Configure environment variables:

`bash
cp .env.example .env
`

5. Configure your .env file:

`env


Flow wallet private key

FLOW_PRIVATE_KEY=xxx

Google AI (Gemini) API key

GEMINI_API_KEY=xxx

Flow network (mainnet, testnet, or emulator)

FLOW_NETWORK=testnet
`

Development

To test:

`bash


Start the project in development mode

pnpm dev

OR run tests

pnpm test
`

Contributing

1. Fork the repository
2. Create a feature branch (git checkout -b feature/new-feature)
3. Commit your changes (git commit -am 'Add new feature')
4. Push to the branch (git push origin feature/new-feature`)
5. Create a Pull Request

Requirements

- Node.js ≥ 18.18.0
- pnpm ≥ 8.0.0
