Decompiled Code Analysis

Decompiled code analysis is the practice of reversing the process of compilation to convert blockchain bytecode back into a human-readable representation. This is often necessary when the original source code is not available or when investigators need to verify what is actually running on the chain.

Decompilation is challenging because the process is not perfect; much of the original context, variable names, and comments are lost during compilation. However, it allows experts to understand the logic of a contract even if the developers have not published the source code.

In the context of smart contract security, this technique is used to hunt for hidden malicious functions or to understand how a proprietary protocol manages its internal logic. It is a vital tool for reverse engineering in adversarial environments where trust cannot be assumed.
