# Required Infrastructure

### Liquidation & Bad Debt Auction Bot

Liquidation bots must be set up to monitor the pool and liquidate any underwater users. The same bot should be used to fill bad debt auctions if one is created. Without one of these bots, users may create bad debt, harming backstop depositors.
