EVM Opcode Manipulation

EVM opcode manipulation involves the direct or indirect use of low-level Ethereum Virtual Machine instructions to influence contract behavior in unintended ways. While developers typically write in high-level languages like Solidity, the final execution is governed by these opcodes.

Advanced attackers may exploit how specific opcodes handle gas, storage, or memory to bypass security checks or optimize exploits. Understanding these low-level operations is crucial for security researchers and auditors looking for deep-seated vulnerabilities.

It is the final frontier of smart contract security, where the theoretical logic meets the actual machine implementation. Mastering this requires deep technical knowledge of the Ethereum protocol's inner workings.
