🔹 Why Use OOP in Solidity?
Code Reusability: Inheritance and libraries reduce redundancy, making it easier to reuse code across contracts.
Modularity: OOP principles help split code into logical components, improving organization and maintainability.
Security: Encapsulation with visibility modifiers protects the internal state, making contracts more secure.
Scalability: A modular approach allows developers to build large-scale applications with manageable components.
🔹 Best Practices for OOP in Solidity
Use Interfaces for Abstraction: Interfaces define function signatures without implementation, helping enforce consistency across contracts. This is especially useful when creating standards (like ERC20 for tokens).
Apply Encapsulation: Keep sensitive data private and expose only what’s necessary through public functions.
Avoid Deep Inheritance Chains: In Solidity, deep inheritance can lead to complexity and increased gas costs. Keep inheritance simple and prioritize clarity.
