# Glass Minting

The mint costs of the glasses are designed to avoid the possibility of a user disposing of their glasses (By listing them at an NFT marketplace or just not using it). The mint cost is designed to be affordable for the users which consequently makes it easier to enter the system and earn rewards.

| Type of Glass | Minting Cost |
| ------------- | ------------ |
| Common        | 10 SPAY      |
| Rare          | 20 SPAY      |
| SuperScript   | 30 SPAY      |

The glasses can only be purchased using SPAY and the mint proceeds will be burned. However, the secondary marketplace trading of glasses will only be facilitated in BNB/ETH. The royalties will also be collected in BNB/ETH.

In the case of free mints, users have to accumulate a certain amount of points. These points can be obtained through different protocol activities such as referrals, watching content, etc. Upon collecting the required amount of points, the user gets a free common glass NFT.

## 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://documentation.script.tv/script-tokens/spay/mechanism-design-of-glasses/glass-minting.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.
