Solana Development, Reimagined.

Helius is the ultimate Solana developer platform. Effortlessly navigate on-chain data with enhanced Solana APIs, webhooks, and top-tier Solana RPCs. We bring together everything required to build serious Solana applications. Start building the future of crypto, now.

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.


deployGeyserPlugin(plugin.so, plugin.config, env)

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
