The vulnerabilities discussed include compromised price feeds, reentrancy issues, and unchecked external calls, among others. Students will learn how these weaknesses arise, their potential impacts, and best practices for addressing them through secure coding and rigorous smart contract audits.

      Lesson Objectives:

      1. Identify and describe nine common vulnerabilities in smart contracts, including vulnerable price feeds, reentrancy, and unchecked external calls.
      2. Explain the potential risks and financial impacts associated with each vulnerability in blockchain applications.
      3. Understand the importance of secure coding practices and audits in mitigating smart contract vulnerabilities.
      4. Evaluate real-world examples of smart contract breaches to understand how vulnerabilities can be exploited and avoided.
