• Abstract: Due to the increasing abuse of fraudulent activities that result in significant financial and reputational harm, Ethereum smart contracts face a significant problem in detecting fraud. Existing monitoring methods typically rely on lease code analysis or physically extracted features, which suffer from scalability and adaptability limitations. In this study, we use graph representation learning to observe purchase trends and find fraudulent deals. We can achieve powerful categorisation performance by using innovative machine learning versions and transforming Ethereum invoice data into graph structures. Our method addresses label imbalance through SMOTE-ENN techniques and evaluates models like Multi-Layer Perceptron ( MLP ) and Graph Convolutional Networks ( GCN). Experimental results show that the MLP type surpasses the GCN in this environment, with domain-specific assessments closely aligned with real-world assessments. This study provides a scalable and efficient way to improve Ethereum's ecosystem's confidence and security.

  We propose a Heterophily-guided Unsupervised Graph fraud dEtection approach (HUGE) for unsupervised GFD. In the estimation module, we design a novel label-free heterophily metric called HALO, which captures the critical graph properties for GFD. In the alignment-based fraud detection module, we develop a joint-GNN architecture with ranking loss and asymmetric alignment loss.

Our work presents the first exact certificate to a poisoning attack ever derived for neural networks, which could be of independent interest.

  Bitcoin has become one of the primary global platforms for cryptocurrency, playing an important role in promoting the diversification of the financial ecosystem. Previous regulatory methods usually detect malicious accounts through feature engineering or large-scale transaction graph mining. We propose an Transaction Graph Compression method named TGC4Eth, which assists malicious detection by lightweighting both features and topology of the transaction graph.

  Graph neural network (GNN) has shown promising performance in various node classification tasks. For transaction data, which could be naturally abstracted to a real-world complex graph, the scarcity of labels and the huge volume of transaction data make it difficult to take advantage of GNN methods. We propose a Self-supervised Incremental Graph learning model (SIEGE) for the phishing scam detection problem.
