说明 | | --------------------- | ------- | --------------------------- | | `graduationThreshold` | uint256 | 毕业所需 KAS 数量 (wei) | | `virtualToken` | uint256 | 曲线虚拟代币储备 | | `virtualKas` | uint256 | 曲线虚拟 KAS 储备 | | `sqrtPriceX96Token0` | uint160 | Uniswap V3 sqrt 价格 (token0) | | `sqrtPriceX96Token1` | uint160 | Uniswap V3 sqrt 价格 (token1) | | `active` | bool | 此参数版本是否激活 | *** ### computeTokenAddress ```solidity theme={null} function computeTokenAddress(bytes32 salt, address creator) external view returns (address) ``` 创建前预测代币合约地址。 *** ### bondingCurve ```solidity theme={null} function bondingCurve() external view returns (address) ``` 返回 BondingCurve 合约地址。 *** ### creationFee ```solidity theme={null} function creationFee() external view returns (uint256) ``` 返回代币创建费用，单位 KAS (wei)。 *** ### authorizedSigner ```solidity theme={null} function authorizedSigner() external view returns (address) ``` 返回平台授权签名者地址。 *** ## 事件 ### Created ```solidity theme={null} event Created( address indexed token, address indexed creator, uint256 indexed tokenId, address pool, string name, string symbol ) ``` ### Buy ```solidity theme={null} event Buy( address indexed token, address indexed buyer, uint256 kasAmount, uint256 tokenAmount, uint256 fee ) ``` ### Sell ```solidity theme={null} event Sell( address indexed token, address indexed seller, uint256 tokenAmount, uint256 kasAmount, uint256 fee ) ``` ## 完整 ABI (JSON) ```json theme={null} [ { "inputs": [{"components": [{"internalType": "string", "name": "name", "type": "string"}, {"internalType": "string", "name": "symbol",
