Blockchain Smart Contract Fortification using Bytecode Analysis to Address Vulnerabilities

Abstract

Smart contracts and blockchain platforms have revolutionised various industries, offering decentralised and transparent execution of agreements. However, they are not immune to security lapses, and the presence of vulnerabilities has led to security issues. This research delves into the realm of smart contract security, employing bytecode analysis as a powerful tool to unveil and rectify vulnerabilities. By meticulously scrutinising the intricate low-level instructions and EVM opcodes, our objective is to unearth potential issues and provide actionable insights for enhancement. Through a compelling case study elucidating a smart contract designed for decentralised electoral integrity, we seamlessly integrate automated tool analysis with manual bytecode examination. Our overarching goal is to elucidate the nuanced process of leveraging bytecode analysis to effectively detect and mitigate vulnerabilities inherent in smart contracts, thus fortifying their robustness and reliability.
