Web3 represents the decentralized evolution of the internet, where users interact directly with blockchain networks. At the heart of this interaction is a robust but typically overlooked element: Remote Procedure Call (RPC). Web3 RPC enables seamless communication between decentralized applications (dApps) and blockchain nodes, acting as the bridge that makes Web3 functional and accessible.

What Is Web3 RPC?

RPC, or Distant Procedure Call, is a protocol that permits a program to execute a procedure or function on one other computer or server without needing to understand its underlying network details. Within the context of Web3, RPC facilitates the interaction between a consumer’s application (like a wallet or dApp) and the blockchain network. These RPC requests are essential for reading data from the blockchain (e.g., checking an account balance) or sending transactions (e.g., transferring tokens or interacting with smart contracts).

For instance, when a user opens their crypto wallet to view token balances, the application sends a Web3 RPC call to a blockchain node requesting the necessary data. The node processes the request and returns the result. This interplay is invisible to the person but critical for the application to function.
