An Initial Exploration of Fine-tuning Small Language Models for Smart Contract Reentrancy Vulnerability Detection

원문 초록

Large Language Models (LLMs) are being used more and more for various coding tasks, including to help coders identify bugs and are a promising avenue to support coders in various tasks including vulnerability detection -- particularly given the flexibility of such generative AI models and tools. Yet for many tasks it may not be suitable to use LLMs, for which it may be more suitable to use smaller language models that can fit and easily execute and train on a developer's computer. In this paper we explore and evaluate whether smaller language models can be fine-tuned to achieve reasonable results for a niche area: vulnerability detection -- specifically focusing on detecting the reentrancy bug in Solidity smart contracts.
