Liquidations on Compound v2
Compound has an open liquidation system. Anyone can purchase assets from undercollateralized positions in exchange for paying off that position's debt. Liquidated assets have a close factor which limits how much debt can be repaid at one time so Compound allows for partial liquidations.
If a position is severely undercollateraized it may be liquidated multiple times. The liquidation penalty is passed to the purchaser through a discount on the debtors asset. This method allows for debt to be cleared from the Compound protocol. To learn more about the liquidation penalities see
If your position is undercollateralized a user or bot may liquidate your position buying your collateral assets at a discount and paying off your debt. Liquidators decide which asset they purchase from the undercollaterlized position if your position has multiple assets as collateral.
