# Important Notes:
* Double-check all wallet addresses and payment details to avoid errors.
* When paying with BTC, ensure the transaction is fully confirmed before proceeding.
* For Solana, make sure your Phantom wallet is properly connected.
* Remember to claim your FNX tokens after the presale ends by connecting your wallet on the platform.
By following these simple steps, you can secure your FNX tokens during this exclusive presale phase and claim them once the presale concludes.

## 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://infinixchain.gitbook.io/infinixchain-docs/how-to-buy-fnx-tokens/important-notes.md?ask=&goal=
```
`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.
