# 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.

### Interest Auction Bot

A bot must also be run to fill interest auctions.&#x20;

{% hint style="danger" %}
It is imperative that all interest auctions are filled. If an interest auction is not filled interest auctions may be permanently stuck for that pool, resulting in a permanent loss of revenue for pool backstop depositors. This may necessitate a pool migration.\
