How to filter transactions by type

Query only swaps, transfers, NFT sales, or other specific transaction types. Pass the type parameter to the Helius Enhanced API.

Try it with different types

Copy the code

// Get transactions filtered by type
// Uses Enhanced API with type parameter
import { Helius } from 'helius-sdk';

const helius = new Helius('YOUR_API_KEY');

async function getFilteredTransactions(
  address: string,
  type: 'TRANSFER' | 'SWAP' | 'NFT_SALE' | 'STAKE_SOL' // etc.
) {
  // Add type parameter to filter results
  const response = await fetch(
    `https://api.helius.xyz/v0/addresses/${address}/transactions?api-key=YOUR_API_KEY&type=${type}&limit=20`
  );

  const transactions = await response.json();
  return transactions;
}

// Example: Get only SWAP transactions
const swaps = await getFilteredTransactions(
  '86xCnPeV69n6t3DnyGvkKobf9FdN2H9oiVDdaMpo2MMY',
  'SWAP'
);

console.log(`Found ${swaps.length} swap transactions`);
swaps.forEach(tx => {
  console.log(`  ${tx.description}`);
});

How to use filters

  • Filter by type: Add type=SWAP to get only swap transactions. Other types: TRANSFER, NFT_SALE, NFT_MINT, STAKE_SOL.
  • Filter by source: Add source=JUPITER to get swaps from a specific DEX. Works with MAGIC_EDEN, TENSOR, RAYDIUM, etc.
  • Combine both: Use type=SWAP&source=JUPITER to get only Jupiter swaps.
