• Design and implement security best practices for smart contract development and deployment.
• Collaborate with blockchain engineers to review architecture and propose secure design improvements.
• Perform penetration testing and threat modeling specific to blockchain and DeFi environments.
• Write detailed audit reports, including vulnerabilities, risk assessments, and recommendations.
• Monitor deployed contracts and blockchain infrastructure for abnormal activities and potential exploits.
• Stay updated on the latest blockchain security threats, vulnerabilities, and industry best practices.
