You can use Maker's contracts to open Vaults (formerly known as CDPs), deposit collateral and generate Dai, trade tokens on decentralized exchanges, and more. The library features a pluggable, service-based architecture, which allows users to easily integrate Maker functionality into their own apps. It also includes convenient configuration presets for out-of-the-box usability and support for both front-end and back-end applications, plus plugins for integrating with Maker governance, hardware wallets, and both Single-Collateral and Multi-Collateral Dai. If you have questions regarding Dai.js that are not answered in the following pages, please reach out to us on the [#dev](https://chat.makerdao.com/channel/dev) channel on [**chat.makerdao.com**](http://chat.makerdao.com/) or create a [Github issue](https://github.com/makerdao/dai.js/issues). --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.skyeco.com/build/dai.js.md?ask=&goal= ``` `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.
