Course Summary

Ethereum Blockchain Solidity Smart Contracts Web3 and Dapps is a Solidity blockchain programming language training course on the Ethereum network, published by Udemy Online Academy. This training course is for beginners with this programming language. In this training course, you will get to know the Solidity programming language, writing smart contracts, understanding blockchain and Web3 tools. At the beginning of this training course, you will get to know Solidity programming language and its basic topics. In this training course, you will learn about writing code and small smart contracts. By mastering the Solidity programming language, you will become familiar with data structures and functions and have a solid foundation for developing advanced contracts.In the rest of this training course, you will get to know the Hardhat framework, one of the most famous frameworks for Ethereum. You gain deep knowledge and skills about this framework with practical exercises and projects. In this training course, you will get acquainted with testing frameworks. You will be able to test your smart contracts using these frameworks and make sure of the reliability of your contract before putting it on the Ethereum network.
