如何找出用於部署 MyEtherWallet 的編譯器版本

如果我在 MyEtherWallet.com 上部署合約，我如何才能找出使用的編譯器版本，用於驗證 etherscan 上的程式碼等？

為了在 MyEtherWallet 上部署合約，您需要字節碼。字節碼包含元數據中的solidity pragma 版本，該版本被轉換為object您自己獲取的字節碼中的參數。

它將使用設置為編譯指示的任何內容進行編譯。

至於驗證。您將需要知道在solidity 程式碼本身中設置了哪些編譯指示。

契約範例：

pragma solidity ^0.4.23;


contract Stack {
   address public owner = msg.sender;
}

範例字節碼：

當您在 MyEtherWallet 上部署時，您會發布您的字節碼。無法檢測到哪個編譯器版本生成了提供的字節碼。你可以在這裡找到更多資訊
