Functions

​
calculateBuyReturnWithParams

​
calculateSellReturnWithParams

    uint256 tokensIn,
    uint256 tokenReserves,
    uint256 kasReserves,
    uint256 vToken,
    uint256 vKas

​
calculateBuyCostWithParams

Calculate how much KAS you need to get a desired amount of tokens. 
function calculateBuyCostWithParams(
    uint256 tokensOut,
    uint256 tokenReserves,
    uint256 kasReserves,
    uint256 vToken,
    uint256 vKas
) external pure returns (uint256 kasIn)
ParameterTypeDescription

tokenReservesuint256Current token reserves from getTokenInfo()
kasReservesuint256Current KAS reserves from getTokenInfo()
vTokenuint256Virtual token from getTokenParamVersion()
vKasuint256Virtual KAS from getTokenParamVersion()

​
getCurrentPrice

Get the current spot price. 
function getCurrentPrice(
    uint256 tokenReserves,
    uint256 kasReserves
) external view returns (uint256 price)

​
virtualToken / virtualKas

function virtualToken() external view returns (uint256)
function virtualKas() external view returns (uint256)
Default virtual reserves configured in the BondingCurve contract. Note: individual tokens may use different values via getTokenParamVersion().

​
curveType

function curveType() external view returns (uint256)
Returns the curve type identifier.
