These also enable governance to reduce borrow collateral factors without triggering the liquidation of existing positions. #### When an account’s borrow balance exceeds the limits set by liquidation collateral factors, it is eligible for liquidation. A liquidator (a bot, contract, or user) can call the absorb function, which relinquishes ownership of the accounts collateral, and returns the value of the collateral, minus a penalty (liquidationFactor), to the user in the base asset. The liquidated user has no remaining debt, and typically, will have an excess (interest earning) balance of the base asset. #### Each absorption is paid for by the protocol’s reserves of the base asset. In return, the protocol receives the collateral assets. If the remaining reserves are less than a governance-set target, liquidators are able to buy the collateral at a discount using the base asset, which increases the protocol’s base asset reserves. --- # 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://lenen-protocol.gitbook.io/lenen-protocol/core-function/liquidation.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.
