Helius

Helius is a comprehensive Solana infrastructure platform offering RPC nodes, APIs, real-time data streaming, and webhooks designed to help developers build and scale applications on Solana efficiently. It targets teams building DeFi protocols, NFT platforms, fintech apps, and other blockchain-based products that require reliable, low-latency access to Solana blockchain data and transaction processing. Helius provides globally distributed RPC nodes optimized for speed and reliability, with options for shared or dedicated nodes and 24/7 technical support from Solana engineers.

The platform's key features include LaserStream, a gRPC-based ultra-low latency data streaming service for blocks, transactions, and account data, and enhanced WebSocket and webhook APIs for real-time event listening and workflow automation. Helius also offers powerful Solana APIs such as the Digital Asset Standard (DAS) for querying NFTs and tokens, priority fee APIs for smart fee estimation, and enhanced transaction APIs that decode instructions and token transfers into human-readable formats. These tools simplify complex Solana data interactions and reduce the engineering overhead for developers.

What sets Helius apart is its enterprise-grade infrastructure with SOC 2 certification, extreme redundancy through redundant node clusters, and global coverage with endpoints across multiple continents. The platform supports scaling from initial development to millions of users without compromising performance or reliability. Notable integrations include major Solana ecosystem projects like Backpack, Phantom, Crossmint, Zeta Markets, and Chainalysis, which rely on Helius for critical infrastructure needs. Developers can get started quickly with a free tier offering 1 million credits and no credit card required, comprehensive documentation, AI-powered docs navigation, and direct support for paid plans.
