Helius

A Solana-focused developer infrastructure platform providing enhanced RPC nodes, webhooks, and DAS API for NFTs and tokens.

Helius — Helius is a Solana-focused blockchain infrastructure provider offering RPC nodes, enhanced APIs, and webhooks specifically optimized for the Solana ecosystem. It provides features like DAS (Digital Asset Standard) API for compressed NFTs, priority fee estimation, and real-time transaction parsing tailored to Solana's architecture.

What Is Helius?

Helius is the leading dedicated infrastructure provider for Solana. While general providers like Alchemy and QuickNode support Solana alongside other chains, Helius focuses exclusively on Solana optimization. Its RPC nodes are tuned for Solana's 400ms block times and high transaction throughput, providing faster response times and better reliability for Solana-native applications.

Helius processes billions of requests monthly and supports major Solana protocols, wallets, and NFT marketplaces.

Helius Enhanced APIs

Helius extends standard Solana RPC with parsed transaction histories, token metadata resolution, and the DAS API for compressed NFTs (cNFTs). The webhooks feature sends real-time notifications for on-chain events — account changes, NFT sales, token transfers — eliminating the need for constant polling. Priority fee estimation APIs help applications bid appropriately during network congestion.

Helius for Trading Applications

Solana trading bots and DeFi frontends require extremely low-latency RPC access. Helius offers dedicated nodes and staked connections that provide transaction-landing advantages. For tools like OpenLiquid's volume bot operating on Solana, reliable RPC infrastructure directly impacts trade execution success rates and speed.
