Smart Contract Vulnerabilities and Detection Methods: A Survey

Abstract

Smart contracts are fundamental to blockchain technology, enabling automated contract execution without intermediaries. Their widespread adoption, particularly on platforms like Ethereum, has led to significant digital asset holdings. However, the immutability of blockchain magnifies the impact of even minor errors during smart contract development, potentially resulting in substantial financial losses. Given the frequency of vulnerabilities in existing contracts, secure smart contract development is essential. This paper conducts a comprehensive review of known vulnerabilities and detection methods to guide a more secure approach to smart contract development and promote safer blockchain ecosystems.
