🚀 From Learning Solidity to Building My First Presale Contract After diving deep into Solidity fundamentals and security, including reentrancy protection, integer overflow/underflow, and exploring useful OpenZeppelin libraries, I’ve successfully built a simple yet gas-optimized presale contract. 💡 Features include: - Users can send ETH and receive tokens in exchange - Manual claiming of tokens after presale ends - Event logging for frontend integration - Gas optimizations using `unchecked` and custom errors - Secure design following Checks-Effects-Interactions (CEI) pattern This project helped me understand not just how to write Solidity contracts, but also how to make them secure and efficient.
