1/19/2022也就是今天，Metroverse的publicsale。我刚好这个时候没有会议，所以打算看看是不是热的一塌糊涂。但是很奇怪Metroverse的合约啥都没有发生，就卖完了。唯一一个成功的mint是第10000个block，也就是最后一个。
https://etherscan.io/tx/0x5f25e7202691ed0b5ccabf3e0640782077f9e29643b58755e6591b5c3ef6415c
其他都去哪里了？？
让我们看看其他都去哪儿了！
https://etherscan.io/tx/0x54993818335b0cf3e083bfddb304d1d33761e095cb92e6fcab6a41d6cdf9c612
我也不知道，这个 0x1b900a675Dbdb008718E7763cc61c592FAcfA3EF 是个什么的合约，我只好去看看它的bytecode，基本上还是不明白，为什么这个可以把这些nft都拿走。
我们只看这个unknown888fdd2e，这个就是这位大神的思路，当然我不是smartcontract的expert，我也就是大概说说想法，注意我高亮的地方：
checkWhietlist
saleActive
计算要多少个钱包，每个钱包mint两个
创建contract去call 这段mem[mem[64] len 892] 代码，如果没有猜错就是创建钱包和mintnft了
剩下的问题是为什么这个contract可以改官方contract里面的数据？
我们再来看看官方如何开始公售的
https://etherscan.io/address/0xc932d6a49d2d8b77b4075e537d142ee6cc1e416a
这个就是官方的call，这个时候科学家把里面的签名拿了，完全一样的call了自己的contract，如果没有猜错，科学家把官方的tx拿到了，然后加大gas，运气好了就赢了。
bonus point: 这儿必须要check owner亚
function mintNFT(uint256 amount, bool stake) public payable { require(!checkWhitelist, "Not public mode"); _mintNFT(amount, "", "", stake);
}
但是也有可能他有别的方式保证自己的成功率，但是我们还没有看出来。
在mint的时候还是要检查owner亚。。。
本来了项目方使用Gnosis来做多重签名是好的，但是这个没有办法避免tx跟监听，然后先做了。应用的场景完全不对了。
