函数

​
calculateBuyReturnWithParams

​
virtualToken / virtualKas

function virtualToken() external view returns (uint256)
function virtualKas() external view returns (uint256)
BondingCurve 合约中配置的默认虚拟储备。注意：各代币可能通过 getTokenParamVersion() 使用不同的值。

​
curveType

function curveType() external view returns (uint256)
返回曲线类型标识符。
