Quick Reference

Check Balance

import { createHelius } from 'helius-sdk';

const helius = createHelius({ apiKey: 'YOUR_KEY' });
const assets = await helius.getAssetsByOwner({
  ownerAddress: 'WALLET_ADDRESS',
  displayOptions: {
    showFungible: true,
    showNativeBalance: true
  }
});

Send SOL

import { Connection, Keypair, SystemProgram, Transaction, sendAndConfirmTransaction, LAMPORTS_PER_SOL } from '@solana/web3.js';

const connection = new Connection('https://mainnet.helius-rpc.com/?api-key=YOUR_KEY');
const tx = new Transaction().add(
  SystemProgram.transfer({
    fromPubkey: sender.publicKey,
    toPubkey: recipientPubkey,
    lamports: amount * LAMPORTS_PER_SOL
  })
);
await sendAndConfirmTransaction(connection, tx, [sender]);

Jupiter Swap

// 1. Get quote
const quote = await fetch(`https://api.jup.ag/swap/v1/quote?inputMint=${inputMint}&outputMint=${outputMint}&amount=${amount}`);

// 2. Build swap transaction
const swap = await fetch('https://api.jup.ag/swap/v1/swap', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    quoteResponse: await quote.json(),
    userPublicKey: wallet.publicKey.toString()
  })
});

// 3. Sign and send
