Introduction to Solidity: level-02

Overview:

  • Master advanced smart contract development with gas optimization, oracles, and DeFi protocols. Deploy production-ready apps with robust security practices.
  • Duration: 3 Months

Topics Covered:

  • Designing and implementing scalable smart contract architectures
  • Advanced security techniques and vulnerability mitigation
  • Integration with decentralized applications (dApps) and oracles
  • Gas optimization and performance tuning
  • Auditing and upgrading smart contracts

Syllabus

Module 1: Introduction to Blockchain & Ethereum

  • Install MetaMask wallet
  • Connect Remix IDE with MetaMask testnet
  • Deploy a โ€œHello Blockchainโ€ contract on a test network

Module 2: Solidity Basics
  • Solidity syntax & structure
  • Variables (value types & reference types)
  • Functions & visibility (public, private, internal, external)

LAB 2
  • Write & deploy a contract with variables and simple functions
  • Store and retrieve data from blockchain

Module 3 : Data Structures in Solidity
  • Arrays (fixed, dynamic)
  • Structs & Enums
  • Mappings

LAB 3
  • Build a simple student record system using struct & mapping
  • Implement an address-to-balance mapping

Module 4 : Control Structures & Error Handling
  • Conditionals & Loops
  • Require, Assert, Revert
  • Custom Errors (Solidity ^0.8.x)

LAB 4
  • Create a contract with require & assert for validation
  • Test error handling using Remix IDE

Module 5 : Functions & Modifiers
  • Pure, View, Payable functions
  • Function overloading
  • Modifiers & their use in access control

LAB 5
  • Create a bank contract with deposit/withdraw using payable
  • Use modifier to restrict withdrawals to owner

Module 6 : Inheritance & Interfaces
  • Single & Multiple Inheritance
  • Abstract Contracts
  • Interfaces & polymorphism

LAB 6
  • Build an Employee contract that inherits from Person
  • Implement an interface-based voting system

Module 7 : Events & Logging
  • Defining & emitting events
  • Event logging in blockchain
  • Listening to events using Web3.js/Ethers.js

LAB 7
  • Write a transaction logger contract
  • Capture logs in Remix console / Ethers.js script

Module 8 : Tokens & Standards (ERC20, ERC721, ERC1155)
  • ERC20 fungible tokens
  • ERC721 NFTs
  • ERC1155 multi-token standard
  • OpenZeppelin libraries

LAB 8

  • Create a simple NFT contract (ERC721) in Remix
  • Test minting & transferring NFTs on a testnet

Module 9 : Advanced Solidity Concepts
  • Gas optimization techniques
  • Libraries in Solidity
  • Assembly & Yul basics
  • Storage vs Memory vs Calldata

LAB 9
  • Optimize a contract by reducing gas usage
  • Use inline assembly for advanced operations

Module 10 : Smart Contract Security
  • Common vulnerabilities (Reentrancy, Overflow/Underflow, Front-running, DoS)
  • Security best practices
  • Using OpenZeppelin Defender & Slither

LAB 10
  • Implement a vulnerable contract & then fix it (e.g., Reentrancy)
  • Run Slither static analysis

Module 11 : Frameworks & Testing
  • Truffle & Hardhat basics
  • Foundry introduction
  • Unit testing & coverage

LAB 11
  • Deploy a contract with Truffle
  • Write unit tests in Hardhat/Foundry
  • Run coverage report

Module 12 : Capstone Project & Deployment

  • Deployment on Ethereum testnets (Goerli, Sepolia)
  • Gas & contract upgradeability (Proxy contracts)

LAB 12
  • Build & deploy a full dApp (examples: Voting system, Crowdfunding, NFT Marketplace, DAO)
  • Host frontend on GitHub Pages / Vercel
  • Deploy backend on Ethereum testnet via Alchemy/Infura


Learning Outcome

  • Master advanced smart contract design, enhance security and performance, integrate with dApps and oracles, and gain skills in auditing and upgrading contracts
