Description
This talk presents a hybrid deep learning framework for detecting multiple smart contract vulnerabilities, combining SecBERT, BiLSTM, attention mechanisms, and expert-crafted features. Tested on real-world datasets, it achieves over 85% F1-scores across seven vulnerability categories, offering a robust solution to strengthen blockchain security.
