AI Technical Summary
Existing technologies have low accuracy and high false alarm rate in smart contract vulnerability detection, cannot identify complex interactive vulnerabilities, lack automatic repair capabilities, and are poorly adaptable to new attack patterns.
A smart contract vulnerability detection and repair system based on heterogeneous graph neural networks is adopted. Through contract parsing, multi-layer graph construction, heterogeneous graph neural network module, vulnerability feature library, vulnerability identification engine and automatic repair module, combined with static taint analysis, formal verification and graph convolutional neural network, deep feature information extraction and automatic repair are achieved.
It achieves a significant improvement in the accuracy of smart contract vulnerability detection, a reduction in false positive rate, the ability to identify multi-level security risks, a high success rate of automatic repair, strong adaptability, and supports large-scale contract detection and repair.
