# How to buy a game?

## 1. Metamask 

You will need a cryptocurrency wallet to navigate the web3 ecosystem. Your unique public address is your login to your account. [<mark style="color:orange;">Metamask</mark>](https://metamask.io/) is a plugin for your browser.

## 2. Polygon&#x20;

The HashUp ecosystem runs on the <mark style="color:purple;">Polygon</mark> blockchain. This means that only on this network it is possible to buy games and log into the platform. To add it just use our add network button and automatically your <mark style="color:orange;">Metamask</mark> with your permission will add this network.

![The button is located in the header of the GameXplorer](/files/qdsFuOSryllhskHm3o1A)

Remember, when moving on the Polygon blockchain you will need native <mark style="color:purple;">MATIC</mark> coins to pay for each transaction. The cost is small, but it is worth it to own some of this cryptocurrency. HashUp provides a small amount of <mark style="color:purple;">MATIC</mark> for users to buy their first game!

### How to buy <mark style="color:purple;">MATIC</mark>?&#x20;

Through a cryptocurrency exchange:&#x20;

{% hint style="warning" %} <mark style="color:purple;">MATIC</mark> must be on the <mark style="color:purple;">Polygon</mark> network!
{% endhint %}

## 3. USDC&#x20;

Buying the game is done with a stable <mark style="color:blue;">USDC</mark> coin. It can be purchased in the same way as <mark style="color:purple;">MATIC</mark> coins. It is required in order to purchase the game on the platform.

## 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://wiki.hashup.it/hashup/platforms/gamexplorer/how-to-buy-a-game.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.
