Solidity Smart Contract Development

Section 1: Simple Storage

Duration: 1h 46min

Section 2: Storage Factory

Duration: 38min

1. Storage factory introduction

2. Setting the project

This lesson explores the concept of composability in smart contracts, particularly in DeFi, and introduces the 'StorageFactory' contract that interacts with and deploys the 'SimpleStorage' contract. It covers setting up the StorageFactory contract in Remix and emphasizes the importance of version consistency in Solidity. Duration: 4min

3. Deploying a contract from a contract

The chapter focuses on deploying a Simple Storage contract in Solidity and saving it to a storage or state variable. It covers the syntax for creating a Simple Storage contract within another contract and demonstrates the deployment and interaction process in Remix. Duration: 3min

4. Solidity imports

This lesson covers the use of the 'import' statement in Solidity for organizing contract files, managing Solidity versions, and the advanced method of 'named imports'. It demonstrates how importing improves workflow and allows for selective inclusion of contract elements. Duration: 5min

5. Use AI to help pt.1

The lesson discusses utilizing AI chat platforms like ChatGPT and Bard to assist in understanding programming concepts. It emphasizes the importance of formulating questions effectively for AI platforms and provides guidance on using these tools for coding assistance. Duration: 4min

6. Interacting with contracts ABI

This lesson teaches how to keep track of contract addresses when deploying new contracts using Solidity's 'new' keyword. It introduces the concept of ABI (Application Binary Interface) for contract interaction and demonstrates how to interact with contracts using ABI and address in Solidity. Duration: 10min

7. Inheritance in Solidity

An introduction to inheritance and overriding in Solidity, showcasing how to extend the functionality of a contract without duplicating it. The lesson involves creating a new contract 'addFiveStorage.sol' that inherits from 'SimpleStorage.sol' and overrides its functions. Duration: 7min

8. Quiz: Storage Factory Recap Quiz

Questions: 3

9. Sections summary and recap

A summary and recap of the lessons covering deploying contracts using the 'new' keyword, importing contracts, named imports, interacting with contracts using ABI, and contract inheritance in Solidity. The lesson celebrates progress made and encourages continued learning. Duration: 2min

Section 3: Fund Me

Duration: 2h

Section 4: AI Prompting

Duration: 23min
