Transactions represent all state changes on Solana. Helius provides multiple ways to read transaction data, from raw RPC methods to enhanced transaction APIs.

​
Getting a Single Transaction

Retrieve transaction details using the standard RPC method: 
const response = await fetch("https://mainnet.helius-rpc.com/?api-key=YOUR_API_KEY", {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    jsonrpc: '2.0',
    id: '1',
    method: 'getTransaction',
    params: [
      '5brUqZacYhjphkFufZsdJoWA3ACTDh7wX5o4ewHiUGPK5zrLWExsFJb1o83q4SidvgegANZMFqocC4cPyymSEdyt',
      {
        encoding: 'json',
        maxSupportedTransactionVersion: 0
      }
    ]
  })
});
const data = await response.json();
console.log('Transaction data:', data);

​
Enhanced Transaction History

For richer transaction history with parsed data: 
const API_KEY = 'YOUR_API_KEY';
const WALLET_ADDRESS = 'DjPi9wgUDTtYuuL6ZNvhgKJgC8gHaRKtHq6K5ESWbGKt';

const response = await fetch(`https://api-mainnet.helius-rpc.com/v0/addresses/${WALLET_ADDRESS}/transactions?api-key=${API_KEY}&limit=10`, {
  method: 'GET',
});
const transactions = await response.json();
console.log('Enhanced transaction history:', transactions);

​
Transaction Status Checking

Check the status of multiple transactions: 
const response = await fetch("https://mainnet.helius-rpc.com/?api-key=YOUR_API_KEY", {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    jsonrpc: '2.0',
    id: '1',
    method: 'getSignatureStatuses',
    params: [
      [
        '5iT4xEsUHJXWuUfX7ypPoP2h2KGLmomsSfdTnjaV67NhRiUptvFTpVM4Gdeve2Mr6Ye8mgFPx4ESLxEPMsK6pmVS',
        '4aRAsUtUSKbz5UAw3z3HZs2wU2NuY614RRfugE8BpfidKrkvjU49VXdSLsT7EPKNRA9KZH1yqkiVKK8aNBoAEdMU'
      ],
      {
        searchTransactionHistory: true
      }
    ]
  })
});
const statuses = await response.json();
console.log('Transaction statuses:', statuses.result);
