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

Basic Agent Setup

import {
  SolanaAgentKit,
  createVercelAITools,
  KeypairWallet,
} from "solana-agent-kit";
import { Keypair } from "@solana/web3.js";
import bs58 from "bs58";

// Import plugins
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";

// Create wallet from private key
const privateKey = bs58.decode(process.env.SOLANA_PRIVATE_KEY!);
const keypair = Keypair.fromSecretKey(privateKey);
const wallet = new KeypairWallet(keypair);

// 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);

// Create tools for AI framework
const tools = createVercelAITools(agent, agent.actions);

Plugins & Actions

Token Plugin (@solana-agent-kit/plugin-token)

// Deploy a new token
const result = await agent.methods.deployToken({
  name: "My Token",
  symbol: "MTK",
  decimals: 9,
  initialSupply: 1000000,
});

// Transfer tokens
await agent.methods.transfer({
  to: "recipient_address",
  amount: 100,
  mint: "token_mint_address", // optional, defaults to SOL
});

// Check balance
const balance = await agent.methods.getBalance({
  tokenAddress: "token_mint_address", // optional
});

NFT Plugin (@solana-agent-kit/plugin-nft)

// Create collection
const collection = await agent.methods.createCollection({
  name: "My Collection",
  symbol: "MYCOL",
  uri: "https://arweave.net/metadata.json",
});

// Mint NFT to collection
const nft = await agent.methods.mintNFT({
  collectionMint: collection.collectionAddress,
  name: "NFT #1",
  uri: "https://arweave.net/nft1.json",
});

DeFi Plugin (@solana-agent-kit/plugin-defi)

// Swap tokens via Jupiter
const swap = await agent.methods.trade({
  outputMint: "target_token_mint",
  inputAmount: 1.0,
  inputMint: "So11111111111111111111111111111111111111112", // SOL
  slippageBps: 50, // 0.5%
});

// Create Raydium CPMM pool
const pool = await agent.methods.createRaydiumCpmm({
  mintA: "token_a_mint",
  mintB: "token_b_mint",
  configId: "config_id",
  mintAAmount: 1000,
  mintBAmount: 1000,
});

Misc Plugin (@solana-agent-kit/plugin-misc)

// Compressed airdrop (cost-efficient)
const airdrop = await agent.methods.sendCompressedAirdrop({
  mintAddress: "token_mint",
  amount: 100,
  recipients: ["addr1", "addr2", "addr3"],
  priorityFeeInLamports: 10000,
});

// Get token price
const price = await agent.methods.getPrice({
  tokenId: "solana", // CoinGecko ID
});

Blinks Plugin (@solana-agent-kit/plugin-blinks)

Execute Solana Actions/Blinks directly:

// Execute a Blink
const result = await agent.methods.executeBlink({
  blinkUrl: "https://example.com/blink",
  params: { /* blink-specific params */ },
});

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"
);
