# Phase 3. Sky Dollar

Anyone can add a gauge to the pool, even if they do not hold veSKYs. Adding a gauge allows you to deposit bribes for a given pool.

The only gauges that can be added are token pairs whitelisted by SKY STOCKS.

### What is Sky Dollar?

Sky Dollar is, in a nutshell, **a seigniorage protocol (also known as a money printer)** that issues SkyUSD, **a convertible currency with a guaranteed redemption rate of $1**. The coin issued in SKY Dollar is **SkyUSD**.

While SkyUSD is not a stable coin and can trade above $1 in the market, if it falls below $1, it can be redeemed for $1 through a redemption process. This simple mechanism is the cornerstone of the SKY hedge fund and all other services.

### Why convertible?

For a convertible currency to function properly and stably, a stable operating entity is essential. Looking specifically at the cryptocurrency market, with all the altcoins and stablecoins swarming the market, only a few companies have a long-standing background.    &#x20;

Many projects have returned to Earth (Terra) after initially taking off for the moon (Luna) at breakneck speed. Many people believed that the foothold they were standing on was the solid Ayers Rock, but in fact it was an air mattress.

On the other hand, SkyUSD has the potential to overcome this natural law.

## 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://sky-web3-vision.gitbook.io/wp/phase-3.-sky-dollar.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.
