The Ethereum API allows applications to connect to an Tabi node that is part of the Tabi blockchain. Developers can interact with on-chain EVM data and send different types of transactions to the network by utilizing the endpoints provided by the API. The API follows a JSON-RPC standard. If not otherwise specified, the interface is derived from the Alchemy Ethereum API: https://docs.alchemy.com/alchemy/apis/ethereum
