Helius

Helius is the premier developer platform for Solana, providing enterprise-grade RPC infrastructure, webhooks, enhanced APIs, and developer tools that power many of the ecosystem's most popular applications. It has become the go-to infrastructure provider for teams building on Solana. Helius offers high-performance RPC nodes with optimized routing and low latency, supporting both standard Solana RPC methods and enhanced endpoints. The enhanced transaction API parses raw Solana transactions into human-readable formats, making it dramatically easier to build transaction histories, activity feeds, and notification systems. The digital asset API (DAS) provides comprehensive NFT and token metadata. The webhook system allows developers to receive real-time notifications for on-chain events — token transfers, NFT sales, program interactions, and more — without running their own indexers or polling nodes. This significantly reduces the infrastructure burden for application developers and enables real-time features that would otherwise require complex blockchain monitoring setups. Helius also offers Solana-specific developer tools including priority fee estimation, transaction simulation, and Jito bundle integration for MEV-aware transaction submission. The platform serves a wide range of clients from solo developers using the free tier to major protocols processing millions of daily requests. The team actively contributes to Solana core development and ecosystem tooling.
