1. What Is an RPC
RPC (Remote Procedure Call) is the interface through which clients — wallets, dapps, bots — communicate with a blockchain node to read state or submit transactions. It is the standard Web3 API protocol.
2. How It Works
A node exposes JSON-RPC methods (eth_blockNumber, eth_getBalance, eth_sendRawTransaction, etc.) over HTTP or WebSocket. Wallets and apps configure an RPC endpoint (public or provider-hosted) to interact with a chain. Requests can read data (no fee) or submit signed transactions. RPC reliability and rate limits shape app behavior.
3. Why It Matters
RPC is the fundamental plumbing of Web3 — every wallet and dapp depends on it. Public RPCs are free but rate-limited; provider RPCs (Alchemy, Infura) offer reliability and analytics. RPC censorship or outages can block users, making decentralized RPC access an emerging priority.
4. Key Facts
- JSON-RPC over HTTP/WebSocket is the standard
- eth_sendRawTransaction broadcasts signed txs
- Public RPCs: cloudflare-eth, drpc.org, chain public endpoints
- Providers add indexing, tracing, and real-time streams
