Liquidations in Spark

A liquidation is a process that occurs when a borrower's health factor goes below 1 due to their collateral value not properly covering their loan/debt value. This might happen when the collateral decreases in value or the borrowed debt increases in value against each other.

In a liquidation, up to 50% of a borrower's debt is repaid and that value + liquidation fee is taken from the collateral available, so after a liquidation that amount liquidated from your debt is repaid.

To avoid liquidation you can raise your health factor by depositing more collateral assets or repaying part of your loan. By default, repayments increase your health factor more than deposits.

Also, it's important to monitor your health factor and keep it high to avoid a liquidation. Keeping your health factor over 2, for example, gives you more of a margin to avoid a liquidation.
