Helius RPC
Helius RPC is Solana infrastructure for standard JSON-RPC reads and writes, WebSocket subscriptions, and Helius-enhanced data methods.
About this tool
The service covers Solana account, block, transaction, token, slot, epoch, fee, and network methods, including transaction submission and simulation. Its WebSocket interface supports standard Solana subscriptions plus Helius extensions for richer account and transaction filtering.
It is intended for Solana dApps, wallets, indexers, trading systems, and backend services that need a managed RPC endpoint. Teams can combine standard protocol methods with Helius APIs such as enhanced transactions, digital-asset queries, and priority-fee estimation where their application requires parsed or indexed data.
