Create2](https://github.com/AmazingAng/WTF-Solidity/blob/main/25_Create2/readme.md)。这个地址会在 `_update()` 函数中用到。 2. `mint()`：铸造函数，仅 `owner` 地址可以调用，用于铸造 `Pixiu` 代币。 3. `_update()`：`ERC20`代币在被转账前会调用的函数。在其中，我们限制了当转账的目标地址 `to` 为 `LP` 的时候，也就是韭菜卖出的时候，交易会 `revert`；只有调用者为`owner`的时候能够成功。这也是貔貅合约的核心。 diff --git a/S11_Frontrun/readme.md b/S11_Frontrun/readme.md index
