Hello everyone! I want to start sharing my knowledge! πŸ€“ Start with Security - always prioritize security when writing smart contracts. Study common vulnerabilities such as reentrancy, integer overflow, and underflow, and use OpenZeppelin to prevent them. Security is not an add-on, it is the foundation. Good luck)
