+# Wata-Board Frontend
+
+Frontend UI for **Wata-Board** — a decentralized utility payment platform on **Stellar / Soroban**.
+
+This is a **React + TypeScript + Vite** app styled with **Tailwind** and wired to **Freighter Wallet** for signing transactions.
+
+## Prerequisites
+
+- **Node.js** (v18+ LTS recommended)
+- **Freighter Wallet** browser extension
+- Stellar testnet account with XLM
+
+## Quick Start
+
+```bash
+# Install dependencies
+npm install
+
+# Run development server
+npm run dev
+
+# Open http://localhost:5173
+```
+
+## Available Scripts
+
+| Script | Description |
+|--------|-------------|
+| `npm run dev` | Start Vite dev server with hot reload |
+| `npm run build` | Create production build with type checking |
+| `npm run lint` | Run ESLint on all files |
+| `npm run preview` | Preview production build locally |
+
+## Project Structure
+
+```
+src/
+├── App.tsx           # Main payment interface
+├── contracts/        # Soroban contract bindings
+│   ├── src/index.ts  # Generated client code
+│   ├── package.json
+│   └── tsconfig.json
+├── main.tsx          # React entry point
+├── index.css         # Global styles
+└── assets/           # Static assets
+```
+
+## Smart Contract Integration
+
+- **Contract ID**: `CDRRJ7IPYDL36YSK5ZQLBG3LICULETIBXX327AGJQNTWXNKY2UMDO4DA`
+- **Network**: Stellar Testnet
+- **RPC**: `https://soroban-testnet.stellar.org`
+
+## Features
+
+- **Meter Payment**: Enter meter ID and amount to pay utility bills
+- **Freighter Integration**: Sign transactions with browser wallet
+- **Real-time Status**: Track transaction progress and results
+- **Testnet Ready**: Pre-configured for Stellar testnet
+
+## Environment Variables
+
+Create `.env` in the project root:
+
+```env
+VITE_CONTRACT_ID=CDRRJ7IPYDL36YSK5ZQLBG3LICULETIBXX327AGJQNTWXNKY2UMDO4DA
+VITE_RPC_URL=https://soroban-testnet.stellar.org
+```
+
+## Freighter Setup
+
+1. Install [Freighter Wallet](https://www.freighter.app/) extension
+2. Create or import an account
+3. Switch to **Testnet** in settings
+4. Fund account with testnet XLM from [Stellar Laboratory](https://laboratory.stellar.org/#account-creator?network=test)
+
+## Troubleshooting
+
+| Issue | Solution |
+|-------|----------|
+| "Freighter not found" | Install extension and refresh page |
+| "Transaction failed" | Check testnet XLM balance |
+| "Build errors" | Run `npm install` to update deps |
+
+## Notes
+
+- The app is currently configured for **Stellar Testnet** only
+- Contract bindings in `src/contracts/` are auto-generated from Soroban CLI
+- Amount must be a positive whole number
+
+## Dependencies
+
+- **React** 19.2.0
+- **Stellar SDK** 14.5.0
+- **Freighter API** 6.0.1
+- **Tailwind CSS** 4.1.18
+- **Vite** 8.0.0-beta.13
