Helius
Solana RPC and data API platform with enhanced transaction parsing and webhooks.
Best for: Solana developers and data teams who need reliable, high-quality RPC access and parsed on-chain data APIs with real-time webhook capabilities.Helius is the leading Solana data infrastructure provider, offering enhanced RPC endpoints, data APIs, and webhooks for developers building on Solana. It goes beyond standard RPC by providing parsed transaction data, NFT metadata, DAS (Digital Asset Standard) APIs, and real-time webhooks.
The platform's enhanced transaction parsing is a major differentiator: instead of receiving raw Solana instruction data (which requires deep knowledge of each program's IDL to decode), Helius returns structured, human-readable transaction summaries showing what actually happened (swaps, NFT transfers, staking actions, etc.).
For analytics teams building on Solana, Helius provides APIs for wallet activity history, token balances, NFT ownership, DeFi position data, and program-level activity. The webhooks feature allows real-time notifications for on-chain events. Helius has become the default data infrastructure layer for serious Solana development.
