# Gasless Transaction

When interacting with programs/contracts on blockchains such as Solana, network fees (gas) are paid to execute transactions. \
\
To enhance the user experience, Wink has integrated a relayer system whereby relayers pay the transaction fees in SOL for users on the platform. This means that users no longer have to worry about gas fees or topping up SOL as fees are paid natively in USDC. Topping up only USDC is sufficient to fully interact within 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://trywink.gitbook.io/wink/benefits/gasless-transaction.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.
