Smart Contract Fundamentals Lab

About This Lab

A rigorous introduction to Solidity — state variables, functions, events, modifiers, inheritance, and security patterns. You'll write a multi-function contract, write unit tests in Hardhat, run a simulated audit, and deploy.

Lab Modules

1. 1
   Solidity deep divelesson

   Types, visibility, modifiers, events, error handling, gas optimization.

   40 min
2. 2
   Build a multi-function contractbuild

   Pause/unpause, access control, reentrancy guard, upgradeability.

   60 min
3. 3
   Write Hardhat unit testsbuild

   describe/it, beforeEach, expect, edge cases, gas reports.

   50 min
4. 4
   Run Slither security analysissimulation

   Static analysis, common vulnerabilities, remediation.

   30 min
5. 5
   Deploy + verifydeploy

   Mainnet vs testnet, verification, post-deploy monitoring.

What You'll Build

• Write production-grade Solidity with security patterns
• Write comprehensive unit tests (100% function coverage)
• Run Slither static analysis and fix vulnerabilities
• Deploy and verify on Polygon Amoy
