DEEP ANALYSIS OF ATTACKS ON SMART CONTRACTS: VULNERABILITIES, METHODS AND COUNTERMEASURES
Smart contracts are self-executing contracts that have gained significant prominence with the advent of blockchain technology. The unique aspect of these contracts is that the terms of the agreement are directly written into the code, eliminating the need for intermediaries and enabling a high degree of automation. These features have made them particularly attractive in the realm of cryptocurrencies and decentralized applications. However, the inherent complexities associated with the design and implementation of smart contracts have led to a host of vulnerabilities. These vulnerabilities can be exploited by attackers, posing significant security risks. In some cases, these risks have resulted in substantial financial losses, highlighting the need for caution and vigilance. This paper provides a comprehensive overview of the various attack vectors and techniques that attackers can use to exploit these vulnerabilities. It also outlines a range of countermeasures that can be employed to mitigate these risks. The objective of this paper is to serve as a valuable resource for researchers, developers, and users alike. It aims to deepen their understanding of the risks associated with smart contracts and provide guidance on how to mitigate these risks effectively.
