# Liquidity Pools

Notional makes fCash available to trade within its built-in AMM-enabled liquidity pools. A Notional liquidity pool holds fCash alongside its currency type (Dai and fDai, for example). A liquidity pool refers to a **maturity:** a Dec 1 2020 liquidity pool holds Dec 1 2020 fCash.

### Maturities

Liquidity pools mature at a set cadence depending on the governance parameter settings. One example would be quarterly pools that mature every 3 months.

### User Types

Three user types interact with Notional liquidity pools: lenders, borrowers, and liquidity providers. Lenders deposit Dai into the pool and receive fDai (a promise to **receive** a fixed amount of Dai at a future date). Borrowers take Dai from the pool and deposit fDai (a promise to **pay** a fixed amount of Dai at a future date). The liquidity provider adds Dai and Dec 1 2020 fDai into the pool which can be lent or borrowed by either party.

## 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.notional.finance/traders/notional-basics/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.
