# Utility

$NIULAI is COSM’s flagship. Utility runs on four lines.

{% stepper %}
{% step %}

## COSM official flagship

The first official token on COSM Launchpad. Later launches, collabs, missions, and traffic treat $NIULAI as the reference. Holding it is holding the first official identity on the pad’s timeline.
{% endstep %}

{% step %}

## 3% tax, 100% burn

3% on buys, 3% on sells, 100% of tax to the blackhole. Holder utility starts with deflation: other people trade, supply shrinks. No marketing cut. No reflection. One rule — burn.
{% endstep %}

{% step %}

## Movie-token bridge

The meme is a bridge, not a claim on the film. $NIULAI is the pasture where cinema attention can settle on-chain: community, missions, and later COSM collabs. It is not box-office equity.
{% endstep %}

## Prairie badges

| Badge   | Ground | Meaning                                       |
| ------- | ------ | --------------------------------------------- |
| Prairie | Grass  | Show up. Hold. Be seen on the field.          |
| Meme    | Wind   | Spread the bull without fake yield talk.      |
| Bridge  | Path   | Help Web2 traffic find the verified contract. |
| Herd    | Herd   | Finish a season or a public-goods task.       |

Badges are a record, not a yield right.
{% endstep %}

## 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://doc.niulai.app/utility.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.
