JSON-RPC

JSON-RPC is a lightweight, remote procedure call protocol that uses JSON for data formatting. It is widely used in the cryptocurrency space, particularly for interacting with blockchain nodes and decentralized exchanges.

JSON-RPC allows a client to call methods on a remote server, passing parameters and receiving results in a standardized, easy-to-parse format. It is a common standard for developers to query blockchain data, submit transactions, and monitor network status.

Because it is simple and language-agnostic, it is highly accessible for building decentralized applications and trading tools. While not as low-latency as specialized websocket streams, it is a versatile and essential tool for interacting with the blockchain layer.

It provides the interface through which many automated trading systems communicate with on-chain protocols. Understanding JSON-RPC is key for any developer or trader looking to engage directly with blockchain infrastructure.
