Smart Contract Vulnerability Detection Under Digital Assets

In the digital asset domain, smart contracts, as an automated execution mechanism, can effectively address many issues in traditional digital asset protection. However, smart contract technology also faces the risk of malicious attacks. The existence of smart contract vulnerabilities primarily stems from two aspects: first, developers may not fully consider potential vulnerabilities when writing the contracts; second, blockchain platforms allow smart contracts to be freely uploaded, but once uploaded, they cannot be modified. This means that if someone discovers a vulnerability, they can exploit it for malicious attacks, causing losses. To address this, this paper proposes and implements a dual-layer smart contract framework aimed at achieving efficient, secure, and flexible digital asset management by combining asset contracts and regulatory contracts. The smart contract factory is used for the batch generation and deployment of asset and regulatory contracts, simplifying the contract creation process and enhancing system scalability. The interaction layer provides user-friendly asset management, while the regulatory layer ensures system security and stability through real-time monitoring and vulnerability detection. Functional testing and performance analysis using Geth and Remix on a local private chain have validated the practicality and reliability of this framework, which has also been successfully applied on a digital asset platform.
