🛠 Usage Example

1️⃣ Import the SDK

import { CardanoToolKit } from 'cardano-agent-kit';

2️⃣ Initialize Wallet

const API_KEY = 'your_blockfrost_api_key';
const TEST_MNEMONIC = [
    'churn',
    'analyst',
    'debate',
    'million',
    'tattoo',
    'enlist',
    'crystal',
    'slide',
    'gallery',
    'airport',
    'squeeze',
    'live',
    'dinosaur',
    'rough',
    'first',
    'south',
    'cave',
    'clerk',
    'divorce',
    'attend',
    'topic',
    'idea',
    'finger',
    'verify',
];

const toolkit = new CardanoToolKit('blockfrost', API_KEY, 'testnet', TEST_MNEMONIC);

3️⃣ Get Wallet Address

const address = await toolkit.getAddress();
console.log('Wallet Address:', address);

4️⃣ Check Wallet Balance

const balance = await toolkit.getBalance();
console.log('Wallet Balance:', balance);

5️⃣ Send ADA (Lovelace)

const recipient = 'addr_test1qz...';
const txHash = await toolkit.sendLovelace(recipient, '1000000'); // 1 ADA
console.log('✅ Transaction Sent! TX Hash:', txHash);

6️⃣ Delegate to a Stake Pool

const stakePoolId = 'pool1a7h89sr6ymj9g2a9tm6e6dddghl64tp39pj78f6cah5ewgd4px0';
const stakingTxHash = await toolkit.registerAndStakeADA(stakePoolId);
console.log('✅ Staking TX Hash:', stakingTxHash);

🧠 AI-Powered Dynamic Tools

Cardano Agent Kit supports AI-powered blockchain tools using Vercel AI SDK and Langchain.

⚡ Create AI-powered Vercel Tools

import { CardanoToolKit, createVercelCardanoTools } from 'cardano-agent-kit';

const toolkit = new CardanoToolKit('blockfrost', API_KEY, 'testnet', TEST_MNEMONIC);
const aiTools = createVercelCardanoTools(toolkit);

🤖 Create AI-powered Langchain Tools

import { CardanoToolKit, createLangchainCardanoTools } from 'cardano-agent-kit';

const toolkit = new CardanoToolKit('blockfrost', API_KEY, 'testnet', TEST_MNEMONIC);
const aiTools = createLangchainCardanoTools(toolkit);

🔀 Create Dynamic Toolsets

Cardano Agent Kit allows dynamic creation of AI tools for blockchain interactions.

Create AI-powered tools dynamically for Vercel AI

import { CardanoToolKit, createVercelAITools } from 'cardano-agent-kit';
import { getAddress, sendLovelace, getBalance, createWallet, mintAsset, burnAsset, sendAsset } from 'cardano-agent-kit';

const toolkit = new CardanoToolKit('blockfrost', API_KEY, 'testnet', TEST_MNEMONIC);
const aiTools = createVercelAITools(toolkit, [
    sendAsset,
    mintAsset,
    burnAsset,
    getAddress,
    sendLovelace,
    getBalance,
    createWallet,
]);

Create AI-powered tools dynamically for Langchain

import { CardanoToolKit, createLangchainTools } from 'cardano-agent-kit';
import { getAddress, sendLovelace, getBalance, createWallet, mintAsset, burnAsset, sendAsset } from 'cardano-agent-kit';

const toolkit = new CardanoToolKit('blockfrost', API_KEY, 'testnet', TEST_MNEMONIC);
const aiTools = createLangchainTools(toolkit, [
    sendAsset,
    mintAsset,
    burnAsset,
    getAddress,
    sendLovelace,
    getBalance,
    createWallet,
]);
