我无法在以太扫描上核实我的合同。

无法在以太扫描上验证我的合同。这是链接- https://ropsten.etherscan.io/address/0xc68c67a1864060631817be1eebdb91e8661fae7a .请帮帮忙。这是紧急情况。

Answer 1

扫描是指探索吗？如图所示，看到所有与合同相关的数据吗？如果是的话，那就适合我了。Etherscan一直在对索引器进行一些维护，可能是因为它没有显示您的合同。

如果不是这样的话，你能详细说明什么是扫描吗？

Answer 2

仅仅因为您在契约中指定使用solidity，0.4.11并不意味着您使用该版本编译它们。

我最近出了这个问题。我就是这样解决的：

我指定了我想要在我的合同中使用的版本，如：pragma solidity ^0.4.11;，然后我重新组合，用另一个版本，Solity0.4.12或类似的版本来部署这些合同。部署没有失败，因为我仍然使用版本0.4，但是生成的字节码不同。

因此，为了解决您的问题，去混合或松露，并检查您在部署合同时使用了哪个可靠的编译器。然后在以太扫描验证器中使用该版本。它可能与合同中规定的不一样。

确保在验证器中指明您使用的是优化器还是不使用优化器。你可能在过去启用过它。

另外，如果您的合同有一些构造函数参数，请确保传递正确的值。
