Chapter 1: Getting Started with Solidity

Solidity is a statically-typed programming language designed for developing smart contracts that run on the Ethereum Virtual Machine (EVM). This chapter covers the fundamental concepts you need to understand before writing your first smart contract.

Key Topics:

  • • Setting up your development environment
  • • Understanding the EVM and gas
  • • Basic syntax and data types
  • • Contract structure and functions
  • • State variables and visibility

Chapter 2: Smart Contract Architecture

Learn how to design robust and scalable smart contracts using proven architectural patterns. This chapter explores contract inheritance, interfaces, libraries, and modular design principles.

Advanced Concepts:

  • • Contract inheritance and polymorphism
  • • Interface design and implementation
  • • Library usage and deployment
  • • Proxy patterns and upgradability
  • • Event logging and monitoring

Chapter 3: Security and Best Practices

Security is paramount in smart contract development. This chapter covers common vulnerabilities, security patterns, and best practices to protect your contracts from attacks and ensure reliable operation.

Security Topics:

  • • Reentrancy attacks and prevention
  • • Integer overflow/underflow protection
  • • Access control and authorization
  • • Front-running and MEV protection
  • • Audit checklist and testing strategies

Practical Examples

Each chapter includes hands-on examples and exercises to reinforce your learning. From simple storage contracts to complex DeFi protocols, you'll build real-world applications.

Example Projects:

  • • Simple token contract (ERC-20)
  • • NFT marketplace
  • • Voting system
  • • Decentralized exchange

Tools Covered:

  • • Hardhat development framework
  • • OpenZeppelin libraries
  • • Remix IDE
  • • Testing with Chai/Mocha

Prerequisites & Requirements
