Why It's Worth Your Time

In blockchain, even a single line of flawed smart contract code can lead to losses worth hundreds of millions of dollars, making security absolutely critical. Vulnerabilities such as reentrancy attacks and issues related to fallback functions have frequently appeared in real-world hacks. This path is designed to help learners build a solid foundation by first understanding the structure of the Ethereum network and EVM, then practicing the identification and exploitation of vulnerabilities within Solidity-based smart contracts through hands-on exercises. It is ideal for those aiming for careers such as blockchain security researchers or smart contract auditors.

Topics Covered

• Understanding the structure of Ethereum and the Ethereum Virtual Machine (EVM)
• Basics of Solidity syntax and smart contract development
• Common smart contract vulnerabilities and exploitation techniques
• Practical exercises on security threats like integer overflow, sender spoofing, and storage manipulation
