# 指数产品

Cook指数产品由一系列代币组成，可追踪标的资产的表现。Cook协议将在以太坊、币安智能链和火币生态链上提供不同的指数产品。

### 产品机制

Cook协议DApp通过去中心化的交易所直接连接。因此，如果指数代币有充足的流动性，用户可以以较低的Gas成本获得其他用户发行过的指数代币。需要注意的是，此类代币的交易规模会受到流动性池子深度的限制，而且可能会出现一些小的滑点。

用户还可以使用标的资产来发行指数代币，即ERC-20代币，亦称ckToken。前提条件是用户需要花费较高的成本拥有所有的组成代币，这种方法可以创造尽可能多的指数代币。 用户能够随时赎回指数代币，并获得相应的标的资产。

我们计划在以下三个生态系统中首先推出指数产品：

以太坊

主流币指数 (CLI)

以太坊DeFi指数（EDI）

## 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, and the optional `goal` query parameter:

```
GET https://cook-protocol.gitbook.io/chinese/current-features-products/index-products.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.
