The world of blockchain and smart contracts is rapidly evolving. This repository serves as a comprehensive guide for anyone looking to dive into Solidity programming. Here, you will find practical examples that cover a wide range of topics, from the basics to more complex concepts.

By following this guide, you will learn how to create, test, and deploy smart contracts on the Ethereum blockchain. The repository is structured to facilitate your learning journey, allowing you to progress at your own pace.

To get started, clone this repository to your local machine:

git clone https://github.com/Mo-yasser12233/100-smart-contracts.git

Once cloned, navigate to the directory:

cd 100-smart-contracts

Before diving into the smart contracts, ensure you have the following tools installed:

• Node.js
• Truffle
• Ganache
• Metamask

These tools will help you compile, test, and deploy your smart contracts efficiently.

After installing the prerequisites, you can install the required packages using npm:

npm install

You can run the smart contracts using Truffle. First, make sure Ganache is running, then execute:

truffle migrate

This command will deploy the contracts to your local blockchain. You can interact with them through the Truffle console:

truffle console

Smart contracts are self-executing contracts with the terms of the agreement directly written into code. They run on the Ethereum blockchain and enable trustless transactions. Here are some key features:

• Autonomy: No need for intermediaries.
• Trust: The code is immutable and transparent.
• Speed: Automated execution reduces delays.
• Savings: Lower transaction costs.

This repository categorizes smart contracts into three difficulty levels:

• Hello World Contract: A simple contract that demonstrates the basics of Solidity.
• Storage Contract: A contract that stores and retrieves data.

• Token Contract: An ERC20 token implementation.
• Voting Contract: A contract that allows users to vote on proposals.

• Crowdfunding Contract: A complex contract for managing crowdfunding campaigns.
• Decentralized Exchange: A contract that facilitates trading of tokens without a central authority.

Each contract includes comments and documentation to help you understand the code.

This repository covers various topics related to blockchain and smart contracts, including:

• Blockchain: Understanding the underlying technology.
• DeFi: Exploring decentralized finance applications.
• Ethereum: Learning about the Ethereum blockchain and its features.
• Smart Contracts: Writing and deploying contracts.
• Web3: Interacting with the Ethereum network using JavaScript.
