However, bad actors have continuously found ways to exploit smart contracts for personal financial gain, which undermines the integrity of the Ethereum blockchain. This paper proposes a computer program called SADA (Static and Dynamic Analyzer), a novel approach to smart contract vulnerability detection using multiple Large Language Model (LLM) agents to analyze and flag suspicious Solidity code for Ethereum smart contracts. SADA not only improves upon existing vulnerability detection methods but also paves the way for more secure smart contract development practices in the rapidly evolving blockchain ecosystem. %K Blockchain %K Ethereum %K Smart Contracts %K Security %K Decentralized Applications %K Web3 %K Cryptocurrency %K Large Language Models %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=140225
