This contract is used to get the purchase and sale return values for an exponential token based curve.

Functions

getPurchaseCost

Returns the purchase cost using an Exponential Token Based Curve.

function getPurchaseCost(uint256 supply, uint256 initialCost, uint32 scalingFactor, uint256 amount)
    internal
    pure
    returns (uint256 purchaseCost);

Parameters

Name	Type	Description
supply	uint256	token total supply
initialCost	uint256	initial cost of the token
