(English Abstract)
As interest in cryptocurrency and smart contracts grow, many studies are actively analyzing smart contracts. Especially, there are many studies about validating the safety of programs based on the Ethereum virtual machine, is one of the famous cryptocurrency frameworks. However, it is challenging to analyze memory contents of the Ethereum bytecode because of the complex behavior of memory allocation. In this study, we provide a summary of how memory models in high-level programming languages are compiled into EVM bytecodes, and propose a memory abstraction technique that uses abstract values as indices of abstract memory. It enables analyses of linear memory models with pointers which is difficult to analyze because they do not support memory allocation primitive. Through this study, we show that we can perform a more precise memory analysis than the analysis studied in the EVM bytecode.
