OpenAI Launches EVMbench to Strengthen AI-Powered Smart Contract Security

OpenAI is expanding its role in crypto security with the introduction of EVMbench, a new benchmarking framework designed to evaluate how effectively artificial intelligence can analyze and secure Ethereum smart contracts. As decentralized finance (DeFi) platforms continue to safeguard billions of dollars in digital assets, ensuring smart contract security has become more critical than ever.

Smart contracts are self-executing programs deployed on blockchain networks such as Ethereum. They power decentralized exchanges, lending protocols, and a wide range of on-chain financial applications. Because these contracts are typically immutable once launched, even minor vulnerabilities can lead to significant financial losses. This growing risk has intensified the demand for advanced blockchain security solutions.

EVMbench aims to measure whether modern AI models can detect, exploit, and fix smart contract vulnerabilities in realistic scenarios. Developed in collaboration with crypto investment firm Paradigm, the framework uses real-world security flaws previously uncovered through professional audits and competitive security challenges. By relying on authentic vulnerability data, EVMbench provides a practical testing environment for AI systems operating in blockchain ecosystems.

The benchmark evaluates AI performance across three core capabilities: identifying security bugs in Solidity and EVM-based contracts, safely demonstrating exploit scenarios in controlled environments, and repairing vulnerable code without disrupting contract functionality. These metrics are designed to reflect economically meaningful conditions within decentralized finance.

According to OpenAI, smart contracts currently secure more than $100 billion in open-source crypto assets. As AI systems become increasingly capable of reading, generating, and executing code, measuring their effectiveness in high-stakes financial environments is essential. The broader goal is to encourage the defensive use of AI in blockchain audits, vulnerability detection, and smart contract hardening.

With EVMbench, OpenAI is setting a new standard for evaluating AI-driven blockchain security tools, reinforcing the role of artificial intelligence in protecting the future of decentralized finance.
