Definition
An RPC endpoint is a specific network address and interface exposed by a blockchain node that accepts Remote Procedure Call (RPC) requests. It serves as an access point for applications and services to query blockchain data or submit transactions using a defined RPC API. As a piece of infrastructure, it standardizes how external systems communicate with a node over on-chain information channels.
In Simple Terms
An RPC endpoint is the URL or connection point that lets software talk to a blockchain node. It is the technical address where programs send requests to read blockchain data or relay transactions, using a standard RPC format, without needing direct access to the underlying node hardware.
Context and Usage
RPC endpoints are commonly referenced when configuring wallets, decentralized applications, indexers, and other blockchain-integrated services. They are central to how off-chain systems interface with on-chain networks, whether through public infrastructure providers or self-hosted nodes. Discussions about network reliability, rate limits, and data access in blockchain ecosystems frequently revolve around the availability and characteristics of specific RPC endpoints.
