Installation

npm install solana-agent-kit

Quick Start

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

// Initialize with private key and optional RPC URL
const agent = new SolanaAgentKit(
  "your-wallet-private-key-as-base58",
  "https://api.mainnet-beta.solana.com",
  "your-openai-api-key"
);

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

Usage Examples

Deploy a New Token

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

const result = await deploy_token(
  agent,
  9, // decimals
  1000000 // initial supply
);

console.log("Token Mint Address:", result.mint.toString());

Create NFT Collection

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

const collection = await deploy_collection(agent, {
  name: "My NFT Collection",
  uri: "https://arweave.net/metadata.json",
  royaltyBasisPoints: 500, // 5%
  creators: [
    {
      address: "creator-wallet-address",
      percentage: 100,
    },
  ],
});

Swap Tokens

import { trade } from "solana-agent-kit";
import { PublicKey } from "@solana/web3.js";

const signature = await trade(
  agent,
  new PublicKey("target-token-mint"),
  100, // amount
  new PublicKey("source-token-mint"),
  300 // 3% slippage
);

Lend Tokens

import { lendAsset } from "solana-agent-kit";
import { PublicKey } from "@solana/web3.js";

const signature = await lendAsset(
  agent,
  100 // amount
);

Stake SOL

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

const signature = await stakeWithJup(
  agent,
  1 // amount in SOL
);

Fetch Token Price

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

const price = await fetchPrice(
  agent,
  "JUPyiwrYJFskUPiHa7hkeR8VUtAeFoSYbKedZNsDvCN" // Token mint address
);

console.log("Price in USDC:", price);

Send an SPL Token Airdrop via ZK Compression

import {
  sendCompressedAirdrop,
  getAirdropCostEstimate,
} from "solana-agent-kit";
import { PublicKey } from "@solana/web3.js";

(async () => {
  console.log(
    "~Airdrop cost estimate:",
    getAirdropCostEstimate(
      1000, // recipients
      30_000 // priority fee in lamports
    )
  );

  const signature = await sendCompressedAirdrop(
    agent,
    new PublicKey("JUPyiwrYJFskUPiHa7hkeR8VUtAeFoSYbKedZNsDvCN"), // mint
    42, // amount per recipient
    [
      new PublicKey("1nc1nerator11111111111111111111111111111111"),
      // ... add more recipients
    ],
    30_000 // priority fee in lamports
  );
})();
