# Multi-chain Interaction

Dealin Provide a chain-based interactive development environment, so that developers can easily interact with the chain through this environment. The Dealin blockchain interactive development environment provides development components compatible with a variety of working platforms, including SDK for Android and iOS system, javascript library for front-end web applications, and python and PHP libraries for back-end applications.
\
Developers can use these development environments to develop their own blockchain software for data interaction, such as user registration, user information and asset operations. Data on the chain interface allows users to store on the chain of homogeneous or inhomogeneous assets data, and in order to provide the best compatibility and customizable features, block chain system will not mandatory asset data stored in plain manner, users can be more flexible design their own chain data storage structure, so that the information can be more safely through the client and market plug-in analysis.
\
At present, the chain interactive development environment mainly provides the encapsulation of homogeneous and non-homogeneous digital assets and item query, transfer, ownership change, transaction submission, submission of proposal and voting and other functions.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://dealin-1.gitbook.io/dealin/protocol-layer/multi-chain-interaction.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
