# Sentre: An All-in-one Solution
By allowing the native utility token named SEN to be enabled in all pools, the protocol introduces two models named **Simulated Single Exposure** and **Simulated Mesh Exchange**, which solve the problems of Symmetric Deposits and Swap Possibilities respectively. In practice, the AMM will automatically run these algorithms and provide transparency to users. Moreover, it also provides an instrument called the adaptive fee model that reduces the risk of impermanent loss.
For developers, Sentre will open up the chance to access available liquidity. We believe that it will encourage the number of public projects and the liquidity effectiveness.
Finally, Sentre’s products inherited outstanding properties from Solana. We make use of quick block confirmation time based on Proof-of-History on Solana and low fee for user attraction*\[8]*.

## 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.sentre.io/litepaper/sentre-an-all-in-one-solution.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.
