>>60577471These lending pools work like this:
You take out a loan based on collateral deposit and you have a health factor on your loan that reflects the loan to collateral ratio. High health factor means collateral covers your loan with a lot of room leftover to breathe. Poor health factor means your collateral isn't enough to cover your loan.
Problem is these contracts aren't automated. The market could plummet sending your collateral underwater but that doesn't mean you'll get liquidated. Someone has to verify your health factor is underwater so they can liquidate you; aka pay off your loan enough to put you back in a healthy health factor and be rewarded the amount of your collateral to make you healthy as compensation. And then someone has to go any liquidate you. This where MEV search botters come in.
What SVR does is work with MEV botters to find these unhealthy users to liquidate them and split the fees; botters get paid, the platform gets paid (in this case Aave), and Chainlink gets paid. But it doesn't make money unless users are in a position to be liquidated. So if the market is stable, no free money from dumb dumb traders.
Hope that makes sense anon.
