Intelligent contract vulnerability detection method and system, storage medium and equipment

The invention provides an intelligent contract vulnerability detection method and system, a storage medium and equipment. The method comprises the following steps: acquiring a to-be-detected intelligent contract code and processing the to-be-detected intelligent contract code to obtain a to-be-detected intelligent contract code token string vector set; obtaining known smart contract typical vulnerabilities, performing feature extraction, and converting the extracted vulnerability features to obtain a smart contract typical vulnerability feature token string vector set; fusing the smart contract typical vulnerability feature token string vector set and the to-be-detected smart contract code token string vector set to construct a potential vulnerability area graph, and performing model training on the potential vulnerability area graph to obtain a graph neural network vulnerability detection model; and obtaining a target smart contract code and processing the target smart contract code to obtain a target potent
