Real-Time Cryptocurrency Prices - **Supported Cryptos**: Pi Network, Bitcoin (BTC), Ethereum (ETH), Ripple (XRP) - **Currency**: Nigerian Naira (NGN) - **Updates**: Auto-refresh every 30 seconds - **Data Source**: CoinGecko API (free tier) - **Display**: 24-hour price changes with percentage indicators ### 2. Real-Time Stock Prices - **Supported Stocks**: Dangote, GTBank (GTBANK), MTN Nigeria, Airtel Africa - **Currency**: Nigerian Naira (NGN) - **Updates**: Auto-refresh every 60 seconds - **Display**: Stock performance indicators ### 3. Pi Network Payment Integration - **Payment Initiation**: Full Pi SDK integration - **Server Approval**: Backend validation flow - **Transaction Tracking**: Real-time transaction history - **Conversion**: Automatic Pi to Fiat conversion rates - **Security**: Built with Pi Network's security standards ## Project Structure ``` /lib ├── price-service.ts # CoinGecko API integration ├── pi-payment.ts # Pi Network payment service └── system-config.ts # Configuration (existing) /hooks └── use-prices.ts # React hooks for price updates /components ├── crypto-market.tsx # Real-time crypto display └── pi-payment-widget.tsx # Pi payment UI widget /app/api/pi-payment ├── approve/route.ts # Payment approval endpoint ├── complete/route.ts # Payment completion endpoint └── history/route.ts # Transaction history endpoint /app/page.tsx # Main app with integrated features ``` ## Usage Examples ### Displaying Real-Time Crypto Prices ```typescript import { useCryptoPrices } from '@/hooks/use-prices' export function MyComponent() { const { cryptoPrices, cryptoLoading, refreshCryptoPrices } = useCryptoPrices(30000) // Updates every 30 seconds return (

{cryptoPrices.map(crypto => (

{crypto.name}: {crypto.current_price} NGN

Change: {crypto.price_change_percentage_24h}%

))}

) } ``` ### Using the Crypto Market Component ```typescript import { CryptoMarket } from '@/components/crypto-market' export function DashboardPage() { return ( console.log(`Trading ${cryptoId}`)} /> ) } ``` ### Initiating Pi Payments ```typescript import { initiatePiPayment } from '@/lib/pi-payment' async function sendPayment() { try { const result = await initiatePiPayment( 100, // Amount in Pi 'Payment for services', // Memo { userId: 'user123' } // Metadata ) console.log('Payment successful:', result) } catch (error) { console.error('Payment failed:', error) } } ``` ### Using the Pi Payment Widget ```typescript import { PiPaymentWidget } from '@/components/pi-payment-widget' export function CheckoutPage() { return ( { console.log('Payment received:', txId) // Navigate to success page }} onError={(error) => { console.error('Payment error:', error) }} /> ) } ``` ### Converting Crypto Prices ```typescript import { convertCryptoToFiat, convertFiatToCrypto, convertCrypto } from '@/lib/price-service' // Convert Pi to Naira const nairaAmount = await convertCryptoToFiat(100, 'pi', 'ngn') // Convert Naira to Bitcoin const btcAmount = await convertFiatToCrypto(50000, 'bitcoin', 'ngn') // Convert between cryptos const ethAmount = await convertCrypto('bitcoin', 'ethereum', 0.1, 'ngn') ``` ## API Endpoints ### POST `/api/pi-payment/approve` Approves a Pi payment transaction on the server side. **Request:** ```json { "paymentId": "string", "amount": "number", "memo": "string" } ``` **Response:** ```json { "success": true, "message": "Payment approved by server" } ``` ### POST `/api/pi-payment/complete` Completes a Pi payment transaction and records it. **Request:** ```json { "paymentId": "string", "txid": "string" } ``` **Response:** ```json { "success": true, "message": "Payment completed successfully", "transactionId": "string", "txHash": "string" } ``` ### GET `/api/pi-payment/history` Fetches user's payment history. **Query Parameters:** - `limit`: (optional) Number of transactions to fetch (default: 20) **Response:** ```json [ { "id": "tx-001", "from": "user-id", "to": "recipient-id", "amount": 100, "currency": "PI", "status": "completed", "description": "string", "timestamp": 1234567890, "txHash": "0xabc..." } ] ``` ## Environment Configuration The app uses the following configurations from `lib/system-config.ts`: ```typescript export const PI_NETWORK_CONFIG = { SDK_URL: 'https://sdk.pi.app/pi.js', SANDBOX: true, // Set to false for production } export const BACKEND_URLS = { LOGIN: '/api/auth/pi-login', // Add your backend URLs here } ``` Update these values to match your backend configuration. ## Real-Time Updates ### Crypto Prices - Refreshes every 30 seconds by default - Cached for 1 minute to reduce API calls - CoinGecko free API supports up to 50 calls/minute ### Stock Prices - Refreshes every 60 seconds by default - Currently using mock data - integrate with real stock API - Structure ready for providers like Alpha Vantage or IEX Cloud ### Pi Payments - Real-time transaction tracking - Server approval flow prevents fraud - Transaction history accessible on-demand ## Performance Optimizations 1. **Caching**: Price data cached for 1 minute to reduce API calls 2. **Lazy Loading**: Components load prices only when needed 3. **Memoization**: React hooks prevent unnecessary re-renders 4. **Error Handling**: Graceful fallbacks if APIs unavailable ## Security Considerations 1. **Pi SDK Integration**: Uses official Pi Network SDK 2. **Server Approval**: All payments must be approved by backend 3. **Transaction Verification**: Server verifies transaction hash 4. **API Keys**: Sensitive keys should be in environment variables 5. **Rate Limiting**: Implement rate limiting on payment endpoints ## Troubleshooting ### Prices Not Updating - Check CoinGecko API status - Verify network connection - Check browser console for errors - Try manual refresh button ### Pi Payment Fails - Ensure Pi SDK is loaded (`window.Pi` exists) - Check backend endpoints are accessible - Verify payment approval endpoint responds correctly - Check browser console for detailed error messages ### High API Calls - Increase cache duration in `price-service.ts` - Reduce update interval in component props - Implement request batching for multiple cryptos ## Future Enhancements 1. WebSocket integration for real-time streaming prices 2. Multi-currency support (USD, EUR, GBP, etc.) 3. Advanced charting with TradingView 4. Historical price data and analytics 5. Real stock API integration 6. Pi Network contract interactions 7. DeFi protocol integrations 8. Notifications for price alerts ## Support & Resources - **Pi Network**: https://pi.app - **CoinGecko API**: https://www.coingecko.com/api - **E-PAY Documentation**: See README.md ## License This implementation is part of the E-PAY financial application.

) } ``` ### Sending Pi ```typescript import { sendPi } from '@/lib/wallet-service' async function sendPiTransaction() { try { const result = await sendPi( 'wallet_123', 'pi_recipient_address', 50, // amount 'Payment for services' ) console.log('Transaction successful:', result.txHash) } catch (error) { console.error('Send failed:', error) } } ``` ### Staking Pi ```typescript import { stakePi } from '@/lib/wallet-service' async function stakePiTokens() { try { const result = await stakePi( 'wallet_123', 100, // amount to stake '90d' // lockup period ) console.log('Staking reward:', result.apy + '%') console.log('Estimated rewards:', result.estimatedRewards) } catch (error) { console.error('Staking failed:', error) } } ``` ### Swapping Currencies ```typescript import { swapCurrency } from '@/lib/wallet-service' async function swapPiToNaira() { try { const result = await swapCurrency( 'wallet_123', 'PI', 'NGN', 10 // swap 10 Pi ) console.log('You received:', result.toAmount, 'NGN') console.log('Exchange rate:', result.rate) console.log('Fee:', result.fee, 'NGN') } catch (error) { console.error('Swap failed:', error) } } ``` ## Data Models ### WalletData ```typescript { id: string userId: string addresses: { pi: string bitcoin?: string ethereum?: string ripple?: string } balances: { pi: number naira: number bitcoin: number ethereum: number ripple: number } totalValueNGN: number createdAt: number updatedAt: number } ``` ### WalletTransaction ```typescript { id: string type: 'send' | 'receive' | 'stake' | 'unstake' | 'swap' | 'deposit' | 'withdraw' currency: 'PI' | 'NGN' | 'BTC' | 'ETH' | 'XRP' amount: number recipient?: string sender?: string status: 'pending' | 'completed' | 'failed' timestamp: number description: string txHash?: string } ``` ## Security Features 1. **Balance Visibility Toggle** - Users can hide balance display 2. **Secure Addresses** - Unique addresses for each user 3. **Transaction Tracking** - Complete audit trail 4. **Status Verification** - Clear transaction status indicators 5. **Error Handling** - Comprehensive error messages ## Integration with App-Wrapper To enable wallet functionality in your app, update the app-wrapper: ```typescript import { WalletProvider } from '@/contexts/wallet-context' export function AppWrapper({ children }: { children: ReactNode }) { return ( {children} ) } ``` ## Exchange Rates (Mock Data) Current exchange rates used in swaps: - 1 PI = 500 NGN - 1 BTC = 25,000,000 NGN - 1 ETH = 1,500,000 NGN - 1 XRP = 3,500 NGN ## Troubleshooting ### Wallet Not Loading - Check user authentication status - Verify wallet creation API endpoint - Check browser console for errors ### Balance Not Updating - Click refresh button manually - Wait for 30-second auto-refresh - Check internet connection ### Transaction Failed - Verify sufficient balance - Check recipient address format - Review error message in transaction details ## Future Enhancements - [ ] Multi-signature wallet support - [ ] Hardware wallet integration - [ ] Advanced transaction scheduling - [ ] Recurring payments - [ ] Budget tracking - [ ] Investment portfolio analytics - [ ] DeFi protocol integration [V0_FILE]markdown:file="WALLET_SETUP_GUIDE.md" isMerged="true" # E-PAY Wallet Setup Guide ## Quick Start ### Step 1: Update App Wrapper with WalletProvider Since `app/layout.tsx` and `components/app-wrapper.tsx` are locked, you need to manually update the app wrapper. The wallet system includes an enhanced wrapper for reference. **Option A:** Use the provided enhanced wrapper (`components/app-wrapper-with-wallet.tsx`) **Option B:** Manually update `components/app-wrapper.tsx` to include: ```typescript import { WalletProvider } from '@/contexts/wallet-context' export function AppWrapper({ children }: { children: ReactNode }) { return ( {children} ) } ``` ### Step 2: Import Wallet Components The main app page (`app/page.tsx`) already includes wallet components: - `WalletOverview` - Shows balance and addresses - `WalletTransactions` - Lists recent transactions - `useWallet` hook - Access wallet data and methods ### Step 3: Verify API Routes The following API routes have been created and are ready to use: ``` /api/wallet/create /api/wallet/[walletId] /api/wallet/balances/[walletId] /api/wallet/transactions/[walletId] /api/wallet/send-pi /api/wallet/stake-pi /api/wallet/swap ``` ## Project Structure ``` e-pay/ ├── contexts/ │ ├── pi-auth-context.tsx (locked) │ └── wallet-context.tsx (NEW) ├── components/ │ ├── app-wrapper.tsx (locked) │ ├── app-wrapper-with-wallet.tsx (NEW) │ ├── wallet-overview.tsx (NEW) │ ├── wallet-transactions.tsx (NEW) │ └── pi-payment-widget.tsx (existing) ├── lib/ │ ├── wallet-service.ts (NEW) │ ├── pi-payment.ts (existing) │ └── price-service.ts (existing) ├── app/ │ ├── page.tsx (UPDATED) │ └── api/ │ └── wallet/ │ ├── create/ (NEW) │ ├── [walletId]/ (NEW) │ ├── balances/ (NEW) │ ├── transactions/ (NEW) │ ├── send-pi/ (NEW) │ ├── stake-pi/ (NEW) │ └── swap/ (NEW) └── WALLET_DOCUMENTATION.md (NEW) ``` ## Core Features ### 1. Wallet Creation Wallets are automatically created when users authenticate. Each wallet includes: - Pi Network address - Bitcoin address - Ethereum address - Ripple address - Real-time balances for all currencies ### 2. Balance Management - Automatic balance tracking - Multi-currency support - Total value in NGN calculation - 30-second auto-refresh ### 3. Transactions - Send Pi to other wallets - Receive crypto - Stake Pi with APY rewards - Swap currencies with live rates - Deposit and withdraw funds ### 4. Transaction History - View all past transactions - Transaction details modal - Status tracking (pending/completed/failed) - Transaction hash for verification ## Usage in Components ### Basic Wallet Data Access ```typescript import { useWallet } from '@/contexts/wallet-context' export function MyComponent() { const { wallet, balances, isLoading } = useWallet() if (isLoading) return

Loading wallet...

if (!wallet) return

No wallet

return (

Pi Address: {wallet.addresses.pi}

Pi Balance: {balances?.pi}π

Total Value: ₦{wallet.totalValueNGN.toLocaleString()}

) } ``` ### Using Wallet Services ```typescript import { sendPi, stakePi, swapCurrency } from '@/lib/wallet-service' // Send Pi const result = await sendPi(walletId, recipient, 50, 'Payment memo') // Stake Pi const stake = await stakePi(walletId, 100, '90d') // Swap currency const swap = await swapCurrency(walletId, 'PI', 'NGN', 10) ``` ## Environment Variables No additional environment variables are required. The wallet system uses: - Existing Pi Network authentication - Mock API endpoints for demo - CoinGecko API (via price-service.ts) ## Mobile-First Design The wallet components are optimized for mobile: - Responsive card layouts - Touch-friendly buttons - Bottom navigation integration - Fast balance updates - Easy copy-to-clipboard for addresses ## Testing the Wallet ### 1. Wallet Creation Test Users will automatically have a wallet created on first authentication. ### 2. Balance Display Test Navigate to home screen and verify wallet overview displays: - Total balance in NGN - Individual crypto balances - Breakdown by currency ### 3. Transaction History Test Scroll to wallet transactions section and verify: - Mock transactions display - Transaction details modal opens - Status badges show correctly ### 4. API Testing Test API endpoints using curl or Postman: ```bash # Create wallet curl -X POST http://localhost:3000/api/wallet/create \ -H "Content-Type: application/json" \ -d '{"userId":"user123","username":"testuser"}' # Get balances curl http://localhost:3000/api/wallet/balances/wallet_123 # Get transactions curl http://localhost:3000/api/wallet/transactions/wallet_123?limit=20 ``` ## Next Steps 1. **Update App Wrapper**: Unlock `components/app-wrapper.tsx` and add `WalletProvider` 2. **Test Wallet Features**: Navigate through app and test wallet functionality 3. **Backend Integration**: Replace mock API endpoints with real backend 4. **Real Pi Network Integration**: Connect to Pi Network testnet/mainnet 5. **Additional Features**: Add more transaction types, advanced staking, etc. ## Troubleshooting ### Wallet not showing? - Check if user is authenticated - Verify WalletProvider is in app wrapper - Check browser console for errors ### Balances not updating? - Wait 30 seconds for auto-refresh - Click refresh button on wallet overview - Check internet connection ### API errors?

Multi-Provider Authentication #### Sign In Methods: - **Pi Network Username** - Native Pi Network authentication - **Google OAuth** - Google account sign-in - **Apple ID** - Apple account sign-in #### Authentication Context (`contexts/auth-context.tsx`) Manages user authentication state and wallet initialization: ```typescript const { user, // Current authenticated user isAuthenticated, // Boolean flag isLoading, // Loading state error, // Error messages signInWithPi, // Pi sign-in function signInWithGoogle, // Google sign-in signInWithApple, // Apple sign-in initializePiWallet, // Initialize testnet wallet signOut // Sign out function } = useAuth() ``` ### 2. Pi Testnet Wallet #### Features: - Automatic wallet address generation - Testnet support with 1000 test Pi tokens - QR code generation for easy sharing - Copy address functionality - Network status display #### API Endpoint: `/api/wallet/init-testnet` ```typescript POST /api/wallet/init-testnet Body: { userId: string, username: string } Response: { success: boolean walletAddress: string // Generated testnet address network: "testnet" testTokens: 1000 // Test Pi tokens qrCode: string // QR code URL } ``` ### 3. Crypto Swap Functionality #### Supported Currencies: - PI (Pi Network) - NGN (Nigerian Naira) - BTC (Bitcoin) - ETH (Ethereum) - XRP (Ripple) #### Features: - Real-time exchange rates - Instant swap quotes - Price impact calculation - Network fee display - 30-second price lock guarantee #### API Endpoint: `/api/wallet/swap` ```typescript POST /api/wallet/swap Body: { walletId: string fromCurrency: string toCurrency: string fromAmount: number execute?: boolean // Set to true to execute swap } Response: { fromCurrency: string fromAmount: number toCurrency: string toAmount: number // Amount after fees rate: number // Exchange rate fee: number // Network fee (0.5%) impact: number // Price impact percentage txHash: string // Transaction hash timestamp: number } ``` ## API Routes Created ### Authentication 1. **POST** `/api/auth/pi-signin` - Pi Network sign-in 2. **POST** `/api/auth/google-signin` - Google OAuth sign-in 3. **POST** `/api/auth/apple-signin` - Apple OAuth sign-in 4. **POST** `/api/auth/signout` - Sign out session ### Wallet Operations 1. **POST** `/api/wallet/init-testnet` - Initialize Pi testnet wallet 2. **POST** `/api/wallet/swap` - Swap between cryptocurrencies ## Components Created ### SignInScreen (`components/signin-screen.tsx`) Multi-provider authentication UI with: - Pi username/password form - Google sign-in button - Apple sign-in button - Error handling and loading states ### CryptoSwap (`components/crypto-swap.tsx`) Swap interface with: - Real-time quote fetching - Bidirectional currency selection - Exchange rate display - Fee information - Transaction execution ### PiWalletAddress (`components/pi-wallet-address.tsx`) Wallet display component with: - Testnet wallet initialization - Address display with copy button - QR code generation/display - Testnet balance display ## Usage Examples ### Sign In with Pi ```typescript import { useAuth } from '@/contexts/auth-context' function LoginPage() { const { signInWithPi, error, isLoading } = useAuth() const handleSignIn = async (username: string, password: string) => { try { await signInWithPi(username, password) // User is now authenticated } catch (err) { console.error('Sign in failed:', err) } } return ( ) } ``` ### Initialize Pi Wallet ```typescript import { useAuth } from '@/contexts/auth-context' function WalletSetup() { const { initializePiWallet, user } = useAuth() const handleInitialize = async () => { try { const walletAddress = await initializePiWallet() console.log('Wallet initialized:', walletAddress) } catch (err) { console.error('Initialization failed:', err) } } return ( ) } ``` ### Perform Crypto Swap ```typescript async function swapCrypto() { const response = await fetch('/api/wallet/swap', { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify({ walletId: 'user-wallet-123', fromCurrency: 'PI', toCurrency: 'NGN', fromAmount: 100, execute: true }) }) const result = await response.json() console.log('Swap complete:', result.txHash) } ``` ## Testing ### Sign In Flow 1. App redirects to `` if not authenticated 2. User selects sign-in method: - Enter Pi username and password - Or click Google/Apple button 3. User data is stored in context and localStorage 4. App displays main dashboard ### Testnet Wallet 1. Navigate to Investment tab 2. Scroll to "Pi Wallet Address" card 3. Click "Initialize Testnet Wallet" 4. Wallet address generated and displayed 5. Can copy address or show QR code ### Crypto Swap 1. Navigate to Investment tab 2. Scroll to "Swap Crypto" card 3. Select from/to currencies 4. Enter amount to swap 5. View real-time quote with fees 6. Click "Swap" to execute 7. Transaction hash displayed on success ## Security Considerations ### Important Notes - **Private keys are NEVER stored in browser** - Only public wallet addresses - **API requires authentication** - All endpoints should validate user session - **Passwords not stored** - Handled by provider OAuth - **Session management** - Uses localStorage with optional expiration ### Production Implementation Before deploying to production: 1. **OAuth Setup** - Configure Google OAuth 2.0 credentials - Configure Apple OAuth credentials - Set correct redirect URIs 2. **Backend Validation** - Validate all API requests with user authentication - Implement rate limiting on auth endpoints - Use secure session tokens (HTTP-only cookies) - Validate swap requests against user balance 3. **Wallet Security** - Private keys managed on backend only - Use Hardware Security Modules (HSM) - Implement multi-signature wallets - Enable transaction signing on user device 4. **Pi Network Integration** - Register app with Pi Network - Use Pi Network mainnet for production - Implement server-side payment verification - Use Pi Network SDK for authentication ## Troubleshooting ### Issue: Sign in not working - Ensure API routes are properly configured - Check browser console for error messages - Verify OAuth credentials are set correctly ### Issue: Wallet initialization fails - Check userId and username are provided - Verify `/api/wallet/init-testnet` endpoint is accessible - Check browser network tab for API response ### Issue: Swap quote not updating - Verify `/api/wallet/swap` endpoint responds - Check if exchange rate data is available - Look for CORS errors in browser console ## File Structure ``` /contexts - auth-context.tsx # Authentication context & hooks /components - signin-screen.tsx # Sign-in UI component - crypto-swap.tsx # Swap interface component - pi-wallet-address.tsx # Wallet display component /app/api - /auth - pi-signin/route.ts # Pi authentication - google-signin/route.ts # Google authentication - apple-signin/route.ts # Apple authentication - signout/route.ts # Sign out endpoint - /wallet - init-testnet/route.ts # Testnet wallet init - swap/route.ts # Crypto swap (existing) ``` ## Next Steps 1. Configure OAuth providers 2. Connect to Pi Network mainnet 3. Implement database for user accounts 4. Add transaction history persistence 5. Setup email verification 6. Implement 2FA/MFA 7. Add transaction notifications [V0_FILE]typescript:file="lib/testnet-config.ts" isMerged="true" /** * Pi Network Testnet Configuration * Handles testnet mode for development and testing */ export const TESTNET_CONFIG = { ENABLED: true, NETWORK: 'testnet' as const, PI_SDK_URL: 'https://testnet.minepi.com/pi.js', // Testnet API endpoints API: { BASE_URL: 'https://testnet-api.minepi.com', WALLET: 'https://testnet-api.minepi.com/wallet', TRANSACTIONS: 'https://testnet-api.minepi.com/transactions', BALANCE: 'https://testnet-api.minepi.com/balance', }, // Test wallet configuration WALLET: { TEST_ADDRESS: '0x' + 'a'.repeat(40), TEST_PRIVATE_KEY_PREFIX: 'test_', TESTNET_TOKENS: 1000, // Default test tokens MIN_TRANSACTION: 0.01, MAX_TRANSACTION: 10000, }, // Transaction configuration TRANSACTIONS: { GAS_PRICE: 1, // Wei GAS_LIMIT: 21000, NETWORK_FEE_PERCENT: 0.5, CONFIRMATION_TIME_MS: 5000, // Fast confirmation on testnet MAX_RETRIES: 3, }, // Feature flags FEATURES: { ENABLE_PAYMENTS: true, ENABLE_TRANSFERS: true, ENABLE_STAKING: true, ENABLE_SWAPS: true, AUTO_APPROVE_TRANSACTIONS: false, }, // Test accounts for development TEST_ACCOUNTS: [ { address: '0x' + '1'.repeat(40), username: 'testuser1', balance: 500, }, { address: '0x' + '2'.repeat(40), username: 'testuser2', balance: 750, }, ], } export type Network = typeof TESTNET_CONFIG.NETWORK /** * Get environment-specific testnet config */ export function getTestnetConfig() { return { ...TESTNET_CONFIG, IS_TESTNET: process.env.NEXT_PUBLIC_PI_NETWORK === 'testnet', } } /** * Format testnet address for display */ export function formatTestnetAddress(address: string): string { if (address.length <= 8) return address return `${address.slice(0, 6)}...${address.slice(-4)}` } /** * Generate mock transaction ID */ export function generateMockTxId(): string { return `0x${Date.now().toString(16)}${Math.random().toString(16).slice(2, 10)}` } /** * Mock transaction confirmation */ export async function mockTransactionConfirmation( txId: string, delayMs: number = TESTNET_CONFIG.TRANSACTIONS.CONFIRMATION_TIME_MS ): Promise<{ confirmed: true; blockNumber: number }> { return new Promise((resolve) => { setTimeout(() => { resolve({ confirmed: true, blockNumber: Math.floor(Math.random() * 1000000), }) }, delayMs) }) } [V0_FILE]typescriptreact:file="components/pi-transaction.tsx" isMerged="true" 'use client' import { useState } from 'react' import { Button } from '@/components/ui/button' import { Card, CardContent, CardHeader, CardTitle } from '@/components/ui/card' import { Badge } from '@/components/ui/badge' import { Send, CheckCircle, AlertCircle, Loader2, ExternalLink } from 'lucide-react' import { initiatePiPayment, getCurrentNetwork } from '@/lib/pi-payment' import { formatTestnetAddress } from '@/lib/testnet-config' export function PiTransaction() { const [isLoading, setIsLoading] = useState(false) const [error, setError] = useState() const [success, setSuccess] = useState<{ txHash: string amount: number recipient: string }>() const network = getCurrentNetwork() const handleSendTestPi = async () => { setIsLoading(true) setError(undefined) try { const result = await initiatePiPayment( 10, 'Test transaction on ' + network, { purpose: 'testing', network } ) if (result.success) { setSuccess({ txHash: result.txHash || '', amount: 10, recipient: 'Test Recipient', }) } else { setError(result.message || 'Transaction failed') } } catch (err) { setError(err instanceof Error ? err.message : 'Transaction failed') } finally { setIsLoading(false) } } return (

Send Pi Transactions Send Pi tokens to any wallet address on testnet: ``` POST /api/wallet/send-pi { "fromWalletId": string, "toAddress": string, // 0x format "amount": number, "memo": string, "network": "testnet" } ``` **Response:** ```json { "success": true, "transactionId": "tx_123...", "txHash": "0x123...", "status": "completed", "network": "testnet", "amount": 10, "networkFee": "0.05", "totalAmount": "10.05", "confirmation": { "confirmed": true, "blockNumber": 12345 }, "explorerUrl": "https://testnet.minepi.com/explorer/transaction/0x..." } ``` ## Frontend Implementation ### Using Pi Payment Service ```typescript import { initiatePiPayment, getCurrentNetwork } from '@/lib/pi-payment' // Send Pi transaction const result = await initiatePiPayment( 10, // amount 'Payment memo', { purpose: 'testing' } ) if (result.success) { console.log('Transaction hash:', result.txHash) console.log('Network:', result.network) // 'testnet' } // Check current network const network = getCurrentNetwork() // 'testnet' or 'mainnet' ``` ### Pi Transaction Component The app includes a `` component that provides: - Testnet/Mainnet mode indicator - Send button with confirmation UI - Success/error handling - Transaction hash display - Link to block explorer Located in `/components/pi-transaction.tsx` ## Testnet Configuration All testnet settings are in `/lib/testnet-config.ts`: ```typescript export const TESTNET_CONFIG = { ENABLED: true, NETWORK: 'testnet', // Wallet settings WALLET: { TESTNET_TOKENS: 1000, MIN_TRANSACTION: 0.01, MAX_TRANSACTION: 10000, }, // Transaction settings TRANSACTIONS: { GAS_PRICE: 1, NETWORK_FEE_PERCENT: 0.5, CONFIRMATION_TIME_MS: 1000, MAX_RETRIES: 3, }, // Features FEATURES: { ENABLE_PAYMENTS: true, ENABLE_TRANSFERS: true, ENABLE_STAKING: true, ENABLE_SWAPS: true, }, } ``` ## API Endpoints ### Wallet Operations - `POST /api/wallet/init-testnet` - Create testnet wallet - `POST /api/wallet/send-pi` - Send Pi tokens - `GET /api/wallet/[walletId]` - Get wallet info - `GET /api/wallet/balances/[walletId]` - Get balance - `GET /api/wallet/transactions/[walletId]` - Get transaction history - `POST /api/wallet/stake-pi` - Stake Pi tokens - `POST /api/wallet/swap` - Swap currencies ### Payment Operations - `POST /api/pi-payment/approve` - Approve payment - `POST /api/pi-payment/complete` - Complete payment - `GET /api/pi-payment/history` - Payment history ## Testing Transactions ### Step 1: Initialize Wallet ```bash curl -X POST http://localhost:3000/api/wallet/init-testnet \ -H "Content-Type: application/json" \ -d '{"userId":"user1","username":"testuser"}' ``` ### Step 2: Send Pi ```bash curl -X POST http://localhost:3000/api/wallet/send-pi \ -H "Content-Type: application/json" \ -d '{ "fromWalletId":"wallet1", "toAddress":"0x1111111111111111111111111111111111111111", "amount":10, "memo":"Test transaction", "network":"testnet" }' ``` ### Step 3: View in App - Navigate to Transfer tab - Click "Send Pi" button - Transaction appears in 1 second on testnet ## Transaction Flow ``` User clicks "Send Pi" ↓ initiatePiPayment() called ↓ (Testnet) simulateTestnetPayment() ↓ mockTransactionConfirmation() waits 1s ↓ Success response with txHash ↓ Block explorer link generated ↓ User sees confirmation ``` ## Switching to Mainnet To enable mainnet transactions (production): 1. Set environment variable: ```bash NEXT_PUBLIC_PI_NETWORK=mainnet ``` 2. Update testnet config: ```typescript export const TESTNET_CONFIG = { ENABLED: false, // Disable testnet ... } ``` 3. Update API endpoints to real Pi Network: ```typescript API: { BASE_URL: 'https://api.minepi.com', ... } ``` 4. Configure secure key management for production ## Security Considerations ### Testnet - Private keys are generated locally and never exposed - Test tokens have no real value - Fast confirmation for quick testing - Safe for development and QA ### Production (Mainnet) - Private keys stored in secure vault (AWS KMS, HashiCorp Vault) - Real Pi tokens - handle with care - Implement proper authentication - Enable transaction verification - Monitor for fraud - Implement rate limiting - Add additional verification steps for large transactions ## Common Issues ### Transaction Fails - Check wallet balance (minimum: 0.01 Pi) - Verify recipient address format (0x + 40 hex chars) - Check network fees included in total ### Slow Confirmation - Testnet: should be ~1 second - Check gas price settings - Verify network connectivity ### Address Validation - Must be Ethereum-style address - Format: 0x + 40 hexadecimal characters - Use `formatTestnetAddress()` utility for display ## Next Steps 1. **Test on Testnet** - Use the app to send test Pi 2. **Verify Explorer** - Check transaction on block explorer 3. **Production Setup** - Configure mainnet when ready 4. **Add KYC** - Implement user verification for real transactions 5. **Rate Limiting** - Add to prevent abuse 6. **Monitoring** - Set up transaction monitoring and alerts [V0_FILE]typescriptreact:file="contexts/theme-context.tsx" isMerged="true" 'use client' import React, { createContext, useContext, useEffect, useState } from 'react' type Theme = 'light' | 'dark' interface ThemeContextType { theme: Theme toggleTheme: () => void setTheme: (theme: Theme) => void } const ThemeContext = createContext(undefined) export function ThemeProvider({ children }: { children: React.ReactNode }) { const [theme, setThemeState] = useState('light') const [mounted, setMounted] = useState(false) useEffect(() => { setMounted(true) // Get theme from localStorage or system preference const savedTheme = localStorage.getItem('theme') as Theme | null const prefersDark = window.matchMedia('(prefers-color-scheme: dark)').matches const initialTheme = savedTheme || (prefersDark ?
