🚀 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.
