# Unified Liquidity Pools

Siren Flow’s model of using stablecoins as collateral for all options allows the platform to create options for a wide range of assets, regardless of whether token-specific liquidity pools already exist for those assets.

Unified Liquidity Pools enable traders to purchase options for any asset with a reliable price feed, greatly expanding the range of available options. By adopting this model, Siren Flow offers unparalleled flexibility and opportunities for traders in the DeFi options space.

Under the new system, LPs no longer need to maintain different assets in multiple pools in order to earn yield. By consolidating liquidity into a single pool that earns aggregated fees across various markets, Siren Flow simplifies and enhances the user experience.

## 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.siren.xyz/siren-protocol/siren-flow-architecture/unified-liquidity-pools.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.
