# Cauldron V3\_2

The Cauldron V3\_2 is an incremental update to the V3 cauldron enabling the use of more powerful swappers, compatible with aggregators, like 0x.

The new `SwapperV2` need calldata given by the aggregator to work and therefore ask this as an input on the liquidate function, which uses a swapper.

```solidity
function liquidate(
        address[] calldata users,
        uint256[] calldata maxBorrowParts,
        address to,
        ISwapperV2 swapper,
        bytes calldata swapperData
    ) public
```
