# 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.
