Solana wallet with private key
OpenAI API key (for AI agent functionality)
Solana RPC URL

Installation

Start by installing the core package and desired plugins:

npm install solana-agent-kit @solana-agent-kit/plugin-token @solana-agent-kit/plugin-nft @solana-agent-kit/plugin-defi @solana-agent-kit/plugin-misc @solana-agent-kit/plugin-blinks

Additional dependencies:

npm install @solana/web3.js bs58 dotenv @ai-sdk/openai ai

Basic Setup

Environment Setup

Create a .env file with the following variables:

OPENAI_API_KEY=your_openai_api_key
RPC_URL=your_solana_rpc_url
SOLANA_PRIVATE_KEY=your_solana_wallet_private_key

Core Initialization

import { SolanaAgentKit, KeypairWallet } from "solana-agent-kit";
import TokenPlugin from "@solana-agent-kit/plugin-token";
import NFTPlugin from "@solana-agent-kit/plugin-nft";
import DefiPlugin from "@solana-agent-kit/plugin-defi";
import MiscPlugin from "@solana-agent-kit/plugin-misc";
import BlinksPlugin from "@solana-agent-kit/plugin-blinks";
import * as dotenv from "dotenv";
import { Keypair } from "@solana/web3.js";
import bs58 from "bs58";

dotenv.config();

// Initialize wallet
// We are using Keypair for this demo, but it can be connected to Embedded wallet

const keyPair = Keypair.fromSecretKey(
  bs58.decode(process.env.SOLANA_PRIVATE_KEY as string)
);
const wallet = new KeypairWallet(keyPair, process.env.RPC_URL as string);

// Initialize agent with wallet and RPC URL, then add plugins
const agent = new SolanaAgentKit(wallet, process.env.RPC_URL!, {
  OPENAI_API_KEY: process.env.OPENAI_API_KEY,
})
  .use(TokenPlugin)
  .use(NFTPlugin)
  .use(DefiPlugin)
  .use(MiscPlugin)
  .use(BlinksPlugin);

Plugins Overview

Solana Agent Kit v2 uses a modular plugin system to extend functionality:

TokenPlugin: SPL token operations (transfers, balances, minting)
NFTPlugin: NFT operations (minting, transfers, metadata)
DefiPlugin: DeFi operations (swaps, pools, lending)
MiscPlugin: Miscellaneous utilities (airdrop, network info)
BlinksPlugin: Integration with Blinks protocol

Plugins encapsulate related functionality in a modular way, allowing you to include only what your application needs.

Usage Modes

Solana Agent Kit v2 supports two primary usage modes:

1. AI Agent Mode

Create interactive agents that can respond to natural language instructions:

import { createOpenAI } from "@ai-sdk/openai";
import { type Message, streamText } from "ai";
import { randomUUID } from "node:crypto";
import { createVercelAITools } from "solana-agent-kit";

export default async function (agent: SolanaAgentKit) {
  // Create AI tools from agent's actions
  const tools = createVercelAITools(agent, agent.actions);
  
  // Initialize OpenAI client
  const openai = createOpenAI({
    apiKey: process.env.OPENAI_API_KEY as string,
  });
  
  // Initialize message history
  const messages: Message[] = [];
  
  // Interactive chat loop
  while (true) {
    const prompt = await question("\nYou: ");
    if (prompt === "exit") break;
    
    // Add user message to history
    messages.push({
      content: prompt,
      id: randomUUID(),
      role: "user",
    });
    
    // Stream response from the AI model with tools
    const response = streamText({
      model: openai("gpt-4o"),
      tools,
      messages,
      system: `You are a helpful agent that can interact onchain using the Solana Agent Kit...`,
      maxSteps: 5,
    });
    
    // Display streaming response
    process.stdout.write("Agent: ");
    for await (const textPart of response.textStream) {
      process.stdout.write(textPart);
    }
    console.log();
    
    // Add AI response to history
    messages.push({
      content: await response.text,
      id: randomUUID(),
      role: "assistant",
    });
  }
}

2. Programmatic Mode

For direct programmatic usage without AI:

async function programmaticExample(agent: SolanaAgentKit) {
  // Get SOL balance
  const balance = await agent.methods.getBalance();
  console.log("SOL Balance:", balance);
  
  // Airdrop SOL (devnet/testnet only)
  const airdropResult = await agent.methods.requestAirdrop("1");
  console.log("Airdrop result:", airdropResult);
  
  // Transfer SPL token
  const transferResult = await agent.methods.transferToken({
    destination: "recipient_address",
    amount: "1",
    mint: "token_mint_address",
  });
  console.log("Transfer result:", transferResult);
  
  // Swap tokens using Jupiter
  const swapResult = await agent.methods.swapToken({
    inputMint: "input_token_mint",
    outputMint: "output_token_mint",
    amount: "1",
    slippage: 0.5,
  });
  console.log("Swap result:", swapResult);
}

Integrating with Vercel AI SDK

Solana Agent Kit v2 provides built-in integration with Vercel AI SDK:

import { createVercelAITools } from "solana-agent-kit";
import { createAI } from "ai";

// Create AI tools from agent's actions
const tools = createVercelAITools(agent, agent.actions);

// Create AI configuration
const ai = createAI({
  actions: tools,
  initialMessages: [
    {
      role: "system",
      content: "You are a helpful agent that can interact with Solana blockchain."
    }
  ]
});

Custom Plugins

Create your own plugins to extend functionality:

import { SolanaAgentKitPlugin } from "solana-agent-kit";

// Define custom plugin
const CustomPlugin: SolanaAgentKitPlugin = {
  name: "custom",
  
  // Methods that will be available on agent.methods
  methods: {
    customFunction: async (agent, param1: string, param2: number) => {
      // Implementation
      return { status: "success", data: {} };
    }
  },
  
  // Actions for AI integration
  actions: [
    {
      name: "CUSTOM_ACTION",
      description: "Performs a custom function",
      schema: z.object({
        param1: z.string(),
        param2: z.number(),
      }),
      handler: async (agent, input) => {
        const result = await agent.methods.customFunction(
          input.param1,
          input.param2
        );
        return { status: "success", data: result };
      }
    }
  ]
};

// Use the custom plugin
const agent = new SolanaAgentKit(wallet, rpcUrl)
  .use(CustomPlugin);

Error Handling

Implement proper error handling for blockchain operations:

try {
  const result = await agent.methods.transferToken({
    destination: "recipient_address",
    amount: "1",
    mint: "token_mint_address",
  });
  
  console.log("Transfer successful:", result);
} catch (error) {
  if (error.message.includes("insufficient funds")) {
    console.error("Insufficient funds for transfer");
  } else if (error.message.includes("invalid address")) {
    console.error("Invalid recipient address");
  } else {
    console.error("Transfer failed:", error);
  }
}

Utility Functions

For a better developer experience, create utility functions:

// Environment validation
function validateEnvironment(): void {
  const missingVars: string[] = [];
  const requiredVars = ["OPENAI_API_KEY", "RPC_URL", "SOLANA_PRIVATE_KEY"];
  
  requiredVars.forEach((varName) => {
    if (!process.env[varName]) {
      missingVars.push(varName);
    }
  });
  
  if (missingVars.length > 0) {
    console.error("Error: Required environment variables are not set");
    missingVars.forEach((varName) => {
      console.error(`${varName}=your_${varName.toLowerCase()}_here`);
    });
    process.exit(1);
  }
}

// Interactive prompt
const question = (prompt: string): Promise<string> =>
  new Promise((resolve) => rl.question(prompt, resolve));

Mode Selection

Allow users to choose between AI agent and programmatic modes:

async function chooseMode(): Promise<"agent" | "programmatic"> {
  while (true) {
    console.log("\nAvailable modes:");
    console.log("1. agent    - Interactive agent chat mode");
    console.log("2. programmatic    - Programmatic tests written using Jest");
    
    const choice = (await question("\nChoose a mode (enter number or name): "))
      .toLowerCase()
      .trim();
      
    if (choice === "1" || choice === "agent") {
      return "agent";
    } else if (choice === "2" || choice === "programmatic") {
      return "programmatic";
    }
    
    console.log("Invalid choice. Please try again.");
  }
}

    missingVars.forEach((varName) => {
      console.error(`${varName}=your_${varName.toLowerCase()}_here`);
    });
    process.exit(1);
  }
}

validateEnvironment();

async function main() {
  // Choose mode
  const mode = await chooseMode();
  
  // Create wallet
  const keyPair = Keypair.fromSecretKey(
    bs58.decode(process.env.SOLANA_PRIVATE_KEY as string),
  );
  const wallet = new KeypairWallet(keyPair, process.env.RPC_URL as string);
  
  // Initialize agent with plugins
  const agent = new SolanaAgentKit(wallet, process.env.RPC_URL!, {
    OPENAI_API_KEY: process.env.OPENAI_API_KEY,
  })
    .use(TokenPlugin)
    .use(NFTPlugin)
    .use(DefiPlugin)
    .use(MiscPlugin)
    .use(BlinksPlugin);
  
  // Run selected mode
  if (mode === "agent") {
    await aiTests(agent);
  } else {
    await programmaticTests(agent);
  }
  
  rl.close();
}

main()
  .then(() => console.log("All tests completed successfully!"))
  .catch((error) => {
    console.error("Error during tests:", error);
    process.exit(1);
  });

Best Practices

Plugin Selection: Only include plugins your application needs to reduce bundle size
Error Handling: Implement robust error handling for all blockchain operations
Environment Variables: Use environment variables for sensitive information
Testing: Test on devnet before moving to mainnet
Rate Limiting: Be mindful of RPC rate limits in high-volume applications
User Experience: For AI agents, provide clear instructions and examples

Common Issues

Invalid Private Key: Ensure your private key is in the correct format (base58)
RPC Errors: Watch for rate limiting or connectivity issues with RPC providers
Plugin Conflicts: Some plugins may have overlapping functionality
AI Token Limits: Be aware of token limits when using AI models
