# Resolvers

## What Are Resolvers?

Resolvers answer Omniston RFQs with executable quotes and participate in settlement for the selected route.

For an intrachain swap on TON, a resolver prices the route and completes swap settlement. For a cross-chain route, a resolver also provides destination-side liquidity and completes the order-settlement flow on the destination chain.

## How Resolvers Fit Into Omniston

1. **RFQ**: Omniston receives a request for executable pricing.
2. **Quote response**: One or more resolvers return quotes for the requested route and amount.
3. **Selection**: A quote is selected and the source-side action is submitted.
4. **Settlement**: The selected resolver completes either swap settlement on TON or order settlement for a cross-chain route.
5. **Completion**: Omniston exposes settlement progress until the swap or order reaches its final status.

## 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://docs.ston.fi/developer-section/omniston/resolvers.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.
