Solana Agent Kit Development Guide

Build AI agents that autonomously execute 60+ Solana blockchain operations using SendAI's open-source toolkit. Compatible with LangChain, Vercel AI SDK, and Claude via MCP.

Overview

The Solana Agent Kit enables any AI model to:

• Deploy and manage tokens (SPL & Token-2022)
• Create and trade NFTs via Metaplex
• Execute DeFi operations (Jupiter, Raydium, Orca, Meteora)
• Stake SOL, bridge tokens, register domains
• Run in interactive or fully autonomous modes

Integration Patterns

LangChain Integration

import { SolanaAgentKit, createSolanaTools } from "solana-agent-kit";
import { ChatOpenAI } from "@langchain/openai";
import { createReactAgent } from "@langchain/langgraph/prebuilt";
import { MemorySaver } from "@langchain/langgraph";
import { HumanMessage } from "@langchain/core/messages";

async function createLangChainAgent() {
  // Initialize LLM
  const llm = new ChatOpenAI({
    modelName: "gpt-4-turbo-preview",
    temperature: 0.7,
  });

  // Initialize Solana Agent Kit
  const solanaKit = new SolanaAgentKit(
    wallet,
    process.env.RPC_URL!,
    { OPENAI_API_KEY: process.env.OPENAI_API_KEY! }
  )
    .use(TokenPlugin)
    .use(DefiPlugin);

  // Create LangChain tools
  const tools = createSolanaTools(solanaKit);

  // Create agent with memory
  const memory = new MemorySaver();
  const agent = createReactAgent({
    llm,
    tools,
    checkpointSaver: memory,
  });

  return agent;
}

// Run agent
async function chat(agent: any, message: string) {
  const config = { configurable: { thread_id: "solana-agent" } };

  const stream = await agent.stream(
    { messages: [new HumanMessage(message)] },
    config
  );

  for await (const chunk of stream) {
    if ("agent" in chunk) {
      console.log(chunk.agent.messages[0].content);
    }
  }
}

Vercel AI SDK Integration

import { SolanaAgentKit, createVercelAITools } from "solana-agent-kit";
import { openai } from "@ai-sdk/openai";
import { generateText } from "ai";

async function runVercelAgent(prompt: string) {
  const agent = new SolanaAgentKit(wallet, rpcUrl, options)
    .use(TokenPlugin)
    .use(DefiPlugin);

  const tools = createVercelAITools(agent, agent.actions);

  const result = await generateText({
    model: openai("gpt-4-turbo"),
    tools,
    maxSteps: 10,
    prompt,
  });

  return result.text;
}

// Usage
const response = await runVercelAgent(
  "Swap 0.1 SOL for USDC using the best rate"
);

MCP Server for Claude

Install and configure the MCP server for Claude Desktop:

# Install globally
npm install -g solana-mcp

# Or run directly
npx solana-mcp

Add to Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "solana": {
      "command": "npx",
      "args": ["solana-mcp"],
      "env": {
        "RPC_URL": "https://api.mainnet-beta.solana.com",
        "SOLANA_PRIVATE_KEY": "your_base58_private_key",
        "OPENAI_API_KEY": "your_openai_key"
      }
    }
  }
}

Available MCP tools:

• GET_ASSET - Get token/asset info
• DEPLOY_TOKEN - Create new token
• GET_PRICE - Fetch token price
• WALLET_ADDRESS - Get wallet address
• BALANCE - Check balance
• TRANSFER - Send tokens
• MINT_NFT - Create NFT
• TRADE - Execute swap
• REQUEST_FUNDS - Get devnet SOL
• RESOLVE_DOMAIN - Lookup .sol domain
• GET_TPS - Network throughput

Autonomous Mode

Run agent in fully autonomous mode:

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

const agent = new SolanaAgentKit(wallet, rpcUrl, options)
  .use(TokenPlugin)
  .use(DefiPlugin);

// Configure autonomous behavior
const autonomousConfig = {
  intervalMs: 60000,        // Check every minute
  maxActions: 100,          // Max actions per session
  errorRecovery: true,      // Auto-retry on failures
  dryRun: false,            // Set true for testing
};

// Start autonomous loop
async function runAutonomous() {
  while (true) {
    try {
      // Agent decides what to do based on market conditions
      const decision = await agent.analyze({
        context: "Monitor my portfolio and rebalance if needed",
        constraints: [
          "Keep at least 1 SOL for gas",
          "Max 10% allocation per token",
        ],
      });

      if (decision.shouldAct) {
        await agent.execute(decision.action);
      }

      await sleep(autonomousConfig.intervalMs);
    } catch (error) {
      if (autonomousConfig.errorRecovery) {
        console.error("Error, recovering:", error);
        await sleep(5000);
      } else {
        throw error;
      }
    }
  }
}

Creating Custom Actions

Extend the agent with custom actions:

import { Action, Tool, SolanaAgentKit } from "solana-agent-kit";

// Define the Tool (tells LLM HOW to use it)
const myCustomTool: Tool = {
  name: "my_custom_action",
  description: "Does something custom on Solana",
  parameters: {
    type: "object",
    properties: {
      param1: {
        type: "string",
        description: "First parameter",
      },
      param2: {
        type: "number",
        description: "Second parameter",
      },
    },
    required: ["param1"],
  },
};

// Define the Action (tells agent WHEN and WHY to use it)
const myCustomAction: Action = {
  name: "my_custom_action",
  description: "Use this when you need to do something custom",
  similes: ["custom thing", "special operation"],
  examples: [
    {
      input: "Do the custom thing with value X",
      output: "Custom action executed with param1=X",
    },
  ],
  handler: async (agent: SolanaAgentKit, params: any) => {
    const { param1, param2 } = params;

    // Your custom logic here
    const connection = agent.connection;
    const wallet = agent.wallet;

    // Execute Solana operations...

    return {
      success: true,
      result: `Executed with ${param1}`,
    };
  },
};

// Register custom action
agent.registerAction(myCustomAction);
agent.registerTool(myCustomTool);

Best Practices

Security

1. Never expose private keys - Use environment variables
2. Use dedicated wallets - Separate agent wallet from main funds
3. Set spending limits - Implement max transaction amounts
4. Test on devnet first - Always test before mainnet
5. Audit agent actions - Log all operations

Performance

1. Use appropriate RPC - Helius, Triton for production
2. Batch operations - Combine related transactions
3. Handle rate limits - Implement backoff strategies
4. Cache when possible - Price feeds, token metadata

Agent Design

1. Limit plugin scope - Only load needed plugins (reduces hallucinations)
2. Provide clear context - Detailed prompts improve accuracy
3. Add constraints - Prevent unwanted actions
4. Monitor and iterate - Review agent decisions

Guidelines

• Always test on devnet before mainnet
• Set maximum transaction limits
• Monitor agent activity logs
• Use dedicated wallets for agents
• Implement proper error handling
• Keep private keys secure

V2 Highlights

Version 2 represents a complete evolution of the toolkit with key improvements:

Plugin Architecture

V2 directly addresses two major V1 challenges:

1. Security: Input private key method wasn't 100% secure
2. Hallucinations: 100+ aggregate tools caused LLM confusion

The modular plugin system lets you install only what you need, reducing context bloat and hallucinations.

Embedded Wallet Support (New)

V2 integrates with secure wallet providers for enhanced security:

import { TurnkeyWallet, PrivyWallet } from "solana-agent-kit/wallets";

// Turnkey - fine-grained rules and policies
const turnkeyWallet = new TurnkeyWallet({
  organizationId: process.env.TURNKEY_ORG_ID,
  privateKeyId: process.env.TURNKEY_PRIVATE_KEY_ID,
});

// Privy - human-in-the-loop confirmation
const privyWallet = new PrivyWallet({
  appId: process.env.PRIVY_APP_ID,
  requireConfirmation: true,
});

// Initialize agent with secure wallet
const agent = new SolanaAgentKit(turnkeyWallet, rpcUrl, options)
  .use(TokenPlugin)
  .use(DefiPlugin);

Key V2 Benefits

Feature	V1	V2
Wallet Security	Private key input	Embedded wallets (Turnkey, Privy)
Tool Loading	All 100+ tools	Plugin-based, load what you need
LLM Context	Large, caused hallucinations	Minimal, focused context
Human-in-loop	Not supported	Native with Privy
