Documentation

Comprehensive Solana Development Tools. RPCs, APIs, Webhooks, and Data Infrastructure.

Webhooks for Solana Data

Stream Solana transactions and account changes with low latencies and robust fault-tolerance. Enjoy our built-in parsers to fine-tune events you're interested in. Easily build blockchain monitoring, indexing, notifications, automation and much more.


import { Helius, Address, TransactionType } from "helius-sdk";

const helius = new Helius("<your-api-key-here>");

helius.createWebhook({
  accountAddresses: [Address.MAGIC_EDEN],
  transactionTypes: [TransactionType.NFT_LISTING],
  webhookURL: "my-webhook-handler.com/handle",
});

Enhanced Solana APIs

Simplify the interpretation and querying of historical Solana data. Gain context for on-chain transactions with our intelligent parsing systems.

High-Performance Solana RPC Nodes

Enhance your apps with our lightning-fast Solana RPC nodes, optimized for reliability and backed by 24/7 support. Our Solana exclusive focus lets us offer advanced optimizations and domain expertise. Equipped with an advanced archival system, swift indexing mechanisms, and fast accounts calls.


  const web3 = require('@solana/web3.js');

  const conn = new web3.connection("https://rpc.helius.xyz/?api-key=<>")

  (async () => {
    conn.onAccountChange(
      new solanaWeb3.PublicKey("<address>"),
      (updatedAccountInfo, context) =>
        console.log("Updated account info: ", updatedAccountInfo),
      "confirmed"
    );
  })();

Geyser VM

Solana validators expose Geyser plugins for streaming account changes, blocks, and transactions. Geyser VM lets you manage your Geyser plugins and have them run instantly with built-in redundancy and fault-tolerance. We also run dedicated Geyser nodes as a service.

Archival Datalake: Historical Solana Data

Need historical Solana data? We've indexed all historical Solana blocks and index all new blocks in real-time in our Cloud Storage. Run backfills, data pipelines, and ETL Jobs — compatible with integrations from AWS Athena to Spark.


const AWS = require('aws-sdk');

const s3 = new AWS.S3();

// Ask Helius for the bucket and key name!
s3.getObject({ Bucket: bucketName, Key: fileKey }, (err, data) => {
  if (err) {
    console.log('Error reading file: ', err);
  } else {
    console.log('File content: ', data.Body.toString());
  }
});

Build bots, analytics, marketplaces, trackers using our comprehensive Solana APIs.

Stream on-chain events for free with transaction and account webhooks, websockets, or Geyser!

Leading Solana RPCs
