Name	Type	Description
_0	address payable	undefined

calculateSwap

function calculateSwap(contract IERC20 token, uint8 tokenIndexFrom, uint8 tokenIndexTo, uint256 dx) external view returns (uint256)

liqMinAmount	uint256	Specifies the minimum amount of the underlying asset needed for the nodes to execute the redeem/swap
liqDeadline	uint256	Specificies the deadline that the nodes are allowed to try to redeem/swap the LP token*
