MetaMask is a popular browser extension and wallet for managing Ethereum blockchain assets. It provides a user-friendly interface for interacting with decentralized applications (dApps) and executing transactions on the Ethereum blockchain.
json-rpc-engine is a JavaScript library that provides a standardized interface for communicating with Ethereum nodes over JSON-RPC. It abstracts away the underlying details of the JSON-RPC protocol and provides a simple, consistent API for sending and receiving requests and responses.
MetaMask uses json-rpc-engine to communicate with the Ethereum network. When a user interacts with a dApp in MetaMask, the dApp sends JSON-RPC requests to the Ethereum node specified by the user's MetaMask configuration. MetaMask uses json-rpc-engine to handle these requests and retrieve the necessary data from the Ethereum node. Likewise, when a user submits a transaction through MetaMask, json-rpc-engine is used to send the transaction to the Ethereum node for processing.
