Why would a smart contract checker look very closely at parts written in 'assembly code' even if the normal code looks fine?

A smart contract checker meticulously examines parts written in assembly code because this low-level language represents the direct instructions that the blockchain's virtual machine, such as the Ethereum Virtual Machine (EVM), actually executes. While smart contracts are typically authored in high-level languages like Solidity, these languages are translated through a process called compilation into assembly code, also known as bytecode, before they are deployed to the blockchain. The critical point is that the bytecode, not the original source code, is the authoritative version of the program that runs and interacts with the blockchain state. Even if th....
