metamask/eth-json-rpc-middleware

This project, `eth-json-rpc-middleware`, provides Ethereum-related middleware for composing an Ethereum provider using `json-rpc-engine`, intended for developers building Ethereum applications. It is now archived and has been migrated to the MetaMask `core` monorepo, where future development will take place. The middleware is designed for use by developers who need to interact with the Ethereum blockchain, particularly those using `json-rpc-engine`.
