SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Helius provides a unified, high-performance Solana RPC layer, DAS data access, and real-time streaming, reducing integration complexity for developers.

Core Features & Use Cases

  • DAS API: Unified access to NFTs, tokens, compressed assets, and collection data.
  • Enhanced Transactions: Parsed, human-readable transaction data with decoded instructions.
  • Priority Fees: Real-time fee estimates to optimize compute unit usage and push transactions through.
  • Webhooks: Real-time event notifications for swaps, NFT sales, transfers, and more.
  • LaserStream WebSocket/Streaming: Ultra-low-latency data streams for live applications.
  • SDK & Namespaces: Structured APIs under helius., helius.rpc., helius.tx., helius.enhanced., helius.webhooks., helius.ws., helius.zk.*.
  • Use Cases: Build DeFi apps, NFT marketplaces, on-chain analytics dashboards, and infrastructure tooling with reliable RPCs and data access.

Quick Start

Install and initialize the Helius SDK, connect to a Solana RPC endpoint, and perform a sample DAS query and a priority-fee-assisted transaction.

FAQPage Schema
How do I get real-time Solana event notifications for NFT sales and token swaps?▼

To get real-time Solana event notifications, you can configure Helius Webhooks to stream updates for swaps, NFT sales, and transfers directly to your application endpoints as they occur on-chain.

What is the best way to fetch NFT and token metadata on Solana?▼

The best way to fetch Solana NFT and token metadata is using the DAS API, which provides unified access to compressed assets, collection data, and standard tokens through a single query interface.

How do I optimize Solana priority fees to ensure my transactions land?▼

You can optimize Solana priority fees by using real-time fee estimates from Helius, which calculate optimal compute unit usage to help push your transactions through during network congestion.

How do I parse human-readable Solana transaction data?▼

To parse human-readable Solana transaction data, use Helius Enhanced Transactions to decode instruction data into readable formats, simplifying on-chain analytics and transaction tracking.

Can I stream ultra-low-latency Solana data for live applications?▼

Yes, you can stream ultra-low-latency Solana data using the LaserStream WebSocket, which provides real-time data streams designed specifically for high-performance live applications.

Do I need the Helius SDK to query compressed assets on Solana?▼

Yes, you need the Helius SDK and Solana kit installed to query compressed assets, as they provide the structured namespaces and standard endpoints required to access the DAS API.
