🚀 Quick Start

Prerequisites

Node.js 18+
npm or yarn

Installation

# Clone the repository
git clone https://github.com/nirholas/lyra-web3-playground.git
cd lyra-web3-playground

# Install dependencies
npm install

# Start development server
npm run dev

Open http://localhost:3000 in your browser.

Environment Variables

The app runs without configuration, but wallet login, the backend API, RPC access and Supabase-backed features need credentials. Copy the example file and fill it in:

cp .env.example .env

Variable	Purpose
`VITE_PRIVY_APP_ID`	Privy application ID used for wallet / email login
`VITE_API_URL`	Base URL of the backend API (defaults to `http://localhost:3001`)
`VITE_INFURA_API_KEY`	Infura project ID for read-only RPC calls
`VITE_SUPABASE_URL`	Supabase project URL
`VITE_SUPABASE_ANON_KEY`	Supabase anon (public) key

Every VITE_-prefixed value is inlined into the client bundle and is therefore public — never put a private key or server secret in .env. Server-side secrets belong in server/.env (see server/.env.example).

Build for Production

npm run build
npm run preview

❓ Frequently Asked Questions

No! Run npm run dev and open http://localhost:3000 in your browser. Everything runs in your browser.

No! You can learn and practice without any crypto. The IDE has a "JavaScript VM" mode that simulates a blockchain locally. When you're ready to deploy for real, you'll need MetaMask and testnet ETH (which is free).

Yes, it is free to run. No hidden fees, no premium tier. See the LICENSE file for usage terms.

Check the error message - it usually tells you what's wrong
Make sure your Solidity version matches your code
Check the /faq for common issues
Open an issue if you're stuck

Absolutely! That's one of the main use cases. You can share links to specific examples, and students can code along in their browsers. No setup required.

Install MetaMask
Get testnet ETH from a faucet (free)
Connect your wallet on Lyra
Select your network (e.g., Sepolia, Mumbai)
Click "Deploy" - your contract is now on the blockchain!

Please open an issue! We appreciate all feedback.
