# NFT Tresor

Delivering fiat payment possibility for our users brings a new situation to resolve. On Next Earth users can make a purchase by credit card without a wallet and the prior knowledge of crypto solutions like wallet configuration, crypto addresses, browser extensions and so on.

For the first phase Next Earth didn’t use the custodial wallet solution. Instead, we choose a special smart contract solution developed by ourselves called NFT Tresor.

When a Next Earth user purchases without wallet the Land NFT minted on blockchain as usual, and the system stores it in a smart contract connected with the user Next Earth account. When the user anytime decides to create a wallet he/she can claim the NFTs connected to his/her Next Earth account from the NFT Tresor.\ <br>

## 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://whitepaper.nextearth.io/chapter-ii/pillars-of-the-metaverse/economy/nft-tresor.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.
