Helius
Helius is a Solana development optimization service through RPC provision, API building, and webhooks.
What is Helius?
Helius aims to rid the complexity of building on the Solana chain by providing developers APIs for transactions and NFTs, webhooks, and turbocharged RPCs. Developers can build a service that fires notifications or triggers other events when something of effect is registered on the Solana blockchain - such as when a known collector buys new NFTs.
