What is RPC Provider?
An RPC provider is a service that operates blockchain nodes and exposes their RPC interface as an API — enabling developers to interact with blockchains without running their own infrastructure.
WHY IT MATTERS
RPC providers are the plumbing of Web3 development. Alchemy, Infura, and QuickNode run thousands of nodes across multiple chains, providing reliable API access that individual developers would struggle to maintain themselves.
Beyond basic RPC, providers offer: enhanced APIs (token balances, NFT metadata, transaction history), webhooks (real-time notifications), debugging tools, and analytics. These value-added features differentiate providers.
Provider centralization is a concern — if Infura goes down, many dApps become unusable. Decentralized RPC networks (Pocket Network) aim to distribute this infrastructure, though they currently lag in performance and features.
