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?

AI + Blockchain Integration

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

NPM Package Benefits

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

Main Features

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);
  }
}

How to Use?

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

Basic Usage Example:

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:

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

2. Enter the folder:

cd flow-agent-kit

3. Install dependencies:

pnpm install

4. Configure environment variables:

cp .env.example .env

5. Configure your .env file:

# 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:

# Start the project in development mode
pnpm dev

# OR run tests
pnpm test
