I focus on securing decentralized systems through smart contract auditing, protocol analysis, and adversarial security research. With a background in smart contract development and blockchain engineering, I approach security reviews from both the builder's and attacker's perspective, enabling deeper analysis of complex protocol behavior, architecture, and edge cases. My work has included security analysis and reviews of: • Smart contract systems and decentralized applications • Core blockchain infrastructure and protocol components • Developer SDKs and tooling • Layer-1 ecosystems and supporting services Across 30+ security assessments, I've identified 40+ critical vulnerabilities, helping teams address high-impact issues before deployment or production use. I'm particularly interested in protocol-level security, novel attack vectors, and improving the security posture of blockchain infrastructure as the ecosystem continues to scale. ➤ Email: chalghaf.jihed@gmail.com ➤ GitHub: https://github.com/jihed-chalghaf
