EVMbench: A New Frontier in Smart Contract Security

published on 20 February 2026

In the rapidly evolving world of blockchain and smart contracts, the stakes are incredibly high. Smart contracts currently secure over $100 billion in open-source crypto assets, making their security paramount. The introduction of EVMbench by OpenAI marks a pivotal moment in this landscape, offering a benchmark to evaluate AI agents' capability to detect, patch, and exploit vulnerabilities. This tool is not just a breakthrough in technology; it is a call to action for developers and security researchers to leverage AI for more robust security measures.

The Importance of AI in Smart Contract Security

As AI continues to advance, its role in security operations becomes undeniable. According to Cyvers.ai, $500 million was lost in the first quarter of 2023 alone due to attacks on major DeFi projects. This staggering figure underscores the vulnerabilities present within the Web3 ecosystem and highlights the limitations of current security audits. AI's potential to enhance security through automated audits and real-time threat detection is a game changer.

  • Detection: AI agents are trained to audit smart contract repositories, identifying vulnerabilities that might be missed by human auditors.
  • Patching: AI tools help in modifying contracts to eliminate vulnerabilities while ensuring functionality is preserved.
  • Exploitation Mitigation: Deploying AI to simulate and prevent fund-draining attacks can bolster defenses significantly.

EVMbench: A Comprehensive Tool for AI Evaluation

EVMbench is designed to test AI agents across three key modes: detect, patch, and exploit. Each of these components is critical in understanding how AI can be both an attacker and a defender in the cybersecurity domain.

  • Detect Mode: Evaluates AI's ability to recall vulnerabilities and rewards accurate detection.
  • Patch Mode: Challenges AI to fix vulnerabilities without altering the core functionalities of the contract.
  • Exploit Mode: Assesses AI's ability to perform fund-draining attacks in a controlled environment.

By employing a Rust-based harness, EVMbench ensures that evaluations are objective and reproducible. This system allows for deterministic replay of agent transactions while restricting unsafe RPC methods, providing a safe yet rigorous testing ground.

EVMbench evaluates frontier agents across all three modes, with notable improvements seen in exploit settings where AI models achieve significant gains over previous versions.

Case Studies: Real-World Implications

Recent high-profile hacks, such as those on Euler Finance and Safemoon, highlight the critical need for advanced security measures. These incidents serve as stark reminders of the risks that come with digital asset management in decentralized platforms.

By integrating AI into smart contract audits, organizations can significantly reduce the likelihood of such exploits. AI tools, when used alongside traditional manual audits, provide a robust defense mechanism capable of addressing vulnerabilities proactively.

The Dual-Use Nature of AI in Cybersecurity

While AI presents enormous potential for enhancing security, it also poses risks if used maliciously. The dual-use nature of AI in cybersecurity means that the same tools that protect systems could be used to exploit them.

To mitigate these risks, Jina Code Systems advocates for an evidence-based approach. This includes implementing safety training, automated monitoring, and trusted access to advanced capabilities to ensure AI is used responsibly.

Our mitigations include safety training, automated monitoring, trusted access for advanced capabilities, and enforcement pipelines including threat intelligence.

The Future of Smart Contract Security

The introduction of EVMbench is a crucial step towards more secure smart contracts. As AI models become more sophisticated, their ability to detect and mitigate vulnerabilities will only increase. However, as noted by experts, AI should complement, not replace, human oversight in security audits.

Jina Code Systems is committed to helping enterprises harness the full potential of AI in their security operations. By designing and implementing intelligent digital systems, we enable businesses to operate smarter and more securely.
