# Vault Health Each vault has defined Loan-to-Value parameters. Check the app dashboard for current thresholds per vault. To keep its own loan-to-value ratio healthy, the vault may withdraw the required borrow amount from the farmStrategy during the following user transactions: * withdraw → withdrawing from the farmStrategy and repaying part of the lender debt * borrow → withdrawing from the farmStrategy and providing funds to the user * claimRewards → withdrawing from the farmStrategy and providing funds to the user If the farmStrategy has this amount available in its buffer it will provide this amount from the buffer. Where this is not the case it will withdraw the requested amount from the yield farm directly. --- # Agent Instructions: 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.
