EduChainSim: Solidity Playground

EduChainSim is an interactive learning tool designed to help students, developers, and enthusiasts learn, write, and test Solidity smart contracts in a guided and user-friendly environment.

Features

• In-browser Solidity Code Editor with syntax highlighting

• Compile Contracts via backend integration

• Deploy to Local Blockchain (Hardhat)

• Interact with Deployed Contracts using a dynamic ABI-based form

• Gas Usage Leaderboard to compare function call costs

• Guided Lessons Sidebar with beginner-friendly examples and unlockable content

• Validation Messages to guide users on complex input types like structs and arrays

📘 Guided Lessons Sidebar

📊 Gas Usage Leaderboard

Shows how much gas each function call used. Helps learners compare efficiency.

📚 Why EduChainSim?

Learning smart contract development is challenging due to:

• Complicated setup (solc, Hardhat, MetaMask, etc.)

• No real-time feedback for code changes

• Difficult concepts (ABI encoding, gas usage, structs)

EduChainSim solves this by:

• Providing a browser-based editor + live compiler

• Visualizing contract execution & gas usage

• Including interactive, guided Solidity lessons

🔧 How to Run Locally

1. Clone the Repository

git clone https://github.com/Rumpa-Dey/EduChainSim.git
cd EduChainSim

2. Install Dependencies

cd frontend
npm install
cd ../backend
npm install

3. Start Local Blockchain

npx hardhat node

4. Start Backend Compiler Server

cd backend
node server.js

5. Start Frontend

cd frontend
npm start

Now open http://localhost:3000 in your browser
