Welcome to Blockchain Tutorial 19 in our Solidity Mastery Series 2026!
In today’s video, we explore Inheritance in Solidity — one of the most powerful Object-Oriented Programming (OOP) concepts used to build clean, reusable, and scalable smart contracts.

This lecture is 100% beginner-friendly with live coding on Remix IDE

What You Will Learn in This Video
What is Inheritance in Solidity
– Inheritance concept (Parent → Child)
– Real-life programming examples

Benefits of Inheritance
– Code reusability
– Clean & modular smart contracts
– Easy maintenance
– Industry-level development practice

Practical Implementation in Remix IDE
– Line-by-line explanation in Hindi/Urdu

Why Inheritance Is Important
– Used in ERC20, ERC721, ERC1155 token standards
– OpenZeppelin libraries inheritance pe based hoti hain
– Essential for DeFi, NFT, DAO & Web3 projects
– Commonly asked in Blockchain interviews (2026)
