Helius provides developer infrastructure for applications built on Solana. Its services include RPC nodes, transaction delivery tools, gRPC data streaming, webhooks, and APIs for digital-asset information. The company describes a unified stack intended to help applications and trading systems read blockchain data, monitor activity, and submit transactions without operating all supporting infrastructure themselves. Helius also publishes developer documentation and guides for connecting to its endpoints and using its data products. Network coverage and product capabilities vary by service and plan, and features can change as the Solana ecosystem evolves. Developers should check current documentation and service terms before choosing an endpoint for production.
