Some Vault types on Polygon receive 0.05 Qi per block as a borrowing incentive, that is then distributed between all the users who have a healthy Collateral to Debt Ratio (CDR). A healthy CDR is defined as 25% to 270% above the liquidation ratio. For example, a vault with a liquidation ratio of 130% would need to stay between a CDR of 155% and 400% in order to receive vault incentives.
