所有计算函数都是 pure 的——不读取也不修改状态。你可以在链下调用它们进行免 gas 的价格查询。

函数

calculateBuyReturnWithParams

计算给定 KAS 数量能获得多少代币。

function calculateBuyReturnWithParams(
    uint256 kasIn,
    uint256 tokenReserves,
    uint256 kasReserves,
    uint256 vToken,
    uint256 vKas
) external pure returns (uint256 tokensOut)

参数	类型	说明
`kasIn`	uint256	花费的 KAS 数量 (wei)
`tokenReserves`	uint256	当前代币储备，来自 `getTokenInfo()`
`kasReserves`	uint256	当前 KAS 储备，来自 `getTokenInfo()`
`vToken`	uint256	虚拟代币，来自 `getTokenParamVersion()`
`vKas`	uint256	虚拟 KAS，来自 `getTokenParamVersion()`

calculateSellReturnWithParams

计算卖出代币能获得多少 KAS。

function calculateSellReturnWithParams(
    uint256 tokensIn,
    uint256 tokenReserves,
    uint256 kasReserves,
    uint256 vToken,
    uint256 vKas
) external pure returns (uint256 kasOut)

参数	类型	说明
`tokensIn`	uint256	卖出的代币数量 (wei)
`tokenReserves`	uint256	当前代币储备，来自 `getTokenInfo()`
`kasReserves`	uint256	当前 KAS 储备，来自 `getTokenInfo()`
`vToken`	uint256	虚拟代币，来自 `getTokenParamVersion()`
`vKas`	uint256	虚拟 KAS，来自 `getTokenParamVersion()`

calculateBuyCostWithParams

计算要获得指定数量代币需要花费多少 KAS。

function calculateBuyCostWithParams(
    uint256 tokensOut,
    uint256 tokenReserves,
    uint256 kasReserves,
    uint256 vToken,
    uint256 vKas
) external pure returns (uint256 kasIn)

参数	类型	说明
`tokensOut`	uint256	期望的代币数量 (wei)
`tokenReserves`	uint256	当前代币储备，来自 `getTokenInfo()`
`kasReserves`	uint256	当前 KAS 储备，来自 `getTokenInfo()`
`vToken`	uint256	虚拟代币，来自 `getTokenParamVersion()`
`vKas`	uint256	虚拟 KAS，来自 `getTokenParamVersion()`

getCurrentPrice

获取当前现货价格。

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)

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。
