Providing liquidity to a Swap Pool is to a certain extend comparable to giving an earmarked (and thus self-overcollaterialized) loan to the Backstop Pool, which is doing market making on leverage with the Swap Pool liquidity (and the Backstop Pool liquidity as additional collateral). The Backstop Pool guarantees that Swap Pool liquidity providers can withdraw their deposited amount after a 1 block cool-off period (flashloan protection) at any time (not necessarily in the provided token, though) Upon withdrawal from a Swap Pool with coverage ratio below 100%, the Swap Pool liquidity provider can choose to either withdraw their deposits in the provided token, accepting a small loss due to applied slippage - or to choose an "insurance withdrawal" through the backstop pool instead. In the latter case, the liquidity provider receive $USDC (or any surplus tokens of his choice) from the backstop pool at the nominal value of their current LP position, according to the oracle prices, minus a fixed "insurance fee" b (for most assets between 0.1% and 0.4%). --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.nabla.fi/protocol-overview/liquidity-pools/swap-pools.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.
