# The 3 Sale Cards

Learn about the different type of sale cards

Now that you know the format of our IDOs, we should take a look at the different sale cards that you can use to stake your IDIA & vIDIA during our sales.

## So, what are Sale Cards?

Sale Cards are the place for users to stake their IDIA/vIDIA during our Sales. \
\
Every IDO has 3 type of Sale Cards:

* **Standard Pool**
* **Unlimited Pool**
* **Whitelist Sale**

## Standard Pool

In this pool, there is a Staking Cap/Limit to ensure everyone gets their share of the pie and that no whale can come and get it all.&#x20;

The specific amount you can stake varies for each IDO, but generally, the maximum stake per user is around 10,000 IDIA.

## Unlimited Pool

In this pool, you can stake any amount of IDIA/vIDIA tokens, without any limit.&#x20;

There's no maximum amount, so feel free to stake as much as you want. Just keep in mind that others can also stake their tokens in the same way.

## Whitelist Sale

The last sale card is only visible for winners of Marketing campaigns.&#x20;

Throughout the IDO we will do different activities about the project being launched and reward some lucky winners w/ whitelist allocation.&#x20;

For this sale card, there's no need to stake: whatever value you see on the card, you are *whitelisted* to purchase it!

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://impossible.gitbook.io/impossible-finance-faq/launchpad/launchpad-overview/the-3-sale-cards.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
