This mechanism can be triggered when many loans enter a critical zone of "toxic debt." This unhealthy zone is typically identified by a Health Factor dipping below 1. A Health Factor reflects the collateralization ratio of a loan (how much collateral is locked up compared to the borrowed amount). If the Health Factor of a large number of portfolios in the protocol falls below 1, it signifies insufficient collateral to cover the loan, putting the entire system at risk. In this case, an emergency freeze will be initiated, temporarily halting borrowing, lending, and potentially even asset transfers to prevent further deterioration and allow corrective actions. This safeguard helps maintain the stability of the DeFi protocol and protects lenders from widespread loan defaults. --- # 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.superposition.finance/dynamic-margin-and-risk-management/emergency-freeze.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.
