# Clients A client is a specialised class implementation designed for interaction with a specific blockchain. For instance, an Ethereum client enables operations such as retrieving data, sending funds, and generating addresses on the Ethereum blockchain. Blockchain networks are categorised into various types based on their underlying characteristics, for example UTXO (Unspent Transaction Output) or EVM (Ethereum Virtual Machine). In XchainJS for each blockchain type, there exists a generic client. This client is then extended or specialized through specific implementations tailored to individual blockchains. Detailed descriptions of the implementations for each blockchain type are provided in next sections. #### #### #### --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://xchainjs.gitbook.io/xchainjs/clients.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
