When Verified Source Becomes Attack Input: Defending Smart Contracts Against LLM-Based Vulnerability Scanning

Researchers show that publicly verified smart-contract source code can be crafted to mislead LLM-based vulnerability scanners, turning a transparency mechanism into an adversarial input channel.

arXiv:2608.28400v1 Announce Type: new Abstract: Smart contracts are financial programs deployed on blockchains to manage digital assets. To build trust with users and investors, smart contract projects typically publish their source code on blockchain explorers and verify it against the deployed bytecode, making the on-chain program accessible through a human-readable implementation. However, LLM agents are changing the threat model of this disclosure mechanism. By leveraging publicly disclosed

Editorial Analysis

Why it matters

Organisations relying on LLM-based code auditing should recognise that trusted-source code can itself be adversarially crafted to evade or mislead automated analysis.

What to do

Supplement LLM-based smart-contract analysis with traditional static-analysis tools to reduce reliance on a single detection paradigm.
