BugSweeper: Function-Level Detection of Smart Contract Vulnerabilities Using Graph Neural Networks
Smart contracts on Ethereum are prone to critical vulnerabilities like reentrancy, which can lead to substantial financial losses. Traditional rule-based and even current deep learning methods struggle with new threats due to their reliance on predefined heuristics, leading to limited scope and adaptability. BugSweeper addresses these challenges by offering a robust, automated, and scalable solution that bypasses manual preprocessing.

Function-Level Abstraction for Enhanced Context
BugSweeper introduces the Function-Level Abstract Syntax Graph (FLAG), a novel representation combining AST with enriched control-flow and data-flow semantics. This allows for precise vulnerability detection by analyzing code at a granular function level, capturing critical inter-function interactions and variable dependencies that rule-based methods often miss. The 'coverage' parameter allows precise control over the depth of inter-function connections, balancing context and noise.
BugSweeper achieved an impressive 99.87% precision in detecting reentrancy vulnerabilities on the AME dataset, significantly outperforming all other state-of-the-art methods and demonstrating its ability to minimize false positives.
| GNN Configuration | Reentrancy F1 (%) | Unchecked Low-Level Calls F1 (%) | Time Manipulation F1 (%) |
|---|---|---|---|
| Single-stage GAT | 84.77 | 71.43 | 74.72 |
| Single-stage SAGE | 83.11 | 66.20 | 74.77 |
| Two-stage GAT + SAGE | 82.46 | 74.02 | 69.33 |
| Two-stage SAGE + GAT (BugSweeper) | 91.61 | 80.15 | 79.63 |
The Power of CGPool for Graph Abstraction
BugSweeper employs Code Graph Pool (CGPool), a deterministic semantic pooling method. Unlike traditional pooling (TopKPool, SAGPool, ASAPool) which can lose critical information or be computationally expensive, CGPool groups nodes based on their syntactic roles (e.g., merging all nodes of a function declaration into a single supernode). This preserves key high-level relationships and creates a compact, faithful abstraction (Pooled FLAG) for efficient subsequent GNN processing, significantly boosting detection performance across multiple vulnerability types.
The Code Graph Pool (CGPool) achieves the highest multi-class F1-score of 87.32% for vulnerability detection, demonstrating its superior domain effectiveness in handling complex graph structures compared to other pooling methods.
