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)
getTokenParamVersion() 使用不同的值。
curveType
function curveType() external view returns (uint256)
