Implementing robust security measures during the development and deployment of smart contracts is crucial to prevent vulnerabilities that could be exploited, leading to financial losses or system compromise. This involves adhering to secure coding standards, performing comprehensive testing, and conducting specialized audits focused on the smart contract code. A study highlights the importance of integrating security efforts throughout the smart contract development lifecycle. The research indicates that, on average, 29% of the overall development effort is dedicated to security, with significant focus during the construction and testing stages. Practitioners often employ multiple strategies, including code reviews and the use of security tools, to address smart contract security. The study underscores the necessity of proactive defense mechanisms and the adoption of security tools to mitigate risks associated with smart contract vulnerabilities. By implementing these security measures, developers can enhance the resilience of smart contracts against attacks, thereby ensuring the trustworthiness of blockchain applications. Another study emphasizes the importance of integrating security measures throughout the smart contract development lifecycle. The research provides a comprehensive classification of threat mitigation solutions and highlights the necessity of proactive defense mechanisms to mitigate risks associated with smart contract vulnerabilities.
