Description

Introduction of Advanced Solidity:

This course offers an in-depth exploration of Solidity, focusing on advanced concepts for building secure, efficient, and maintainable smart contracts. Participants will learn best practices, tools, and patterns to create robust decentralized applications (DApps) on the Ethereum blockchain. It covers topics such as gas optimization, security vulnerabilities, contract testing, and interoperability with other blockchain technologies.

Prerequisites

• Basic Knowledge of Solidity (Understanding of functions, modifiers, events, and basic data types)
• Familiarity with Ethereum Blockchain (Gas fees, transactions, and Ethereum Virtual Machine)
• Experience with Smart Contract Development Tools (Remix, Hardhat, or Truffle)
• Basic Programming Skills in JavaScript or Python (for DApp interactions and testing)
