Project Mappers - Web3 Implementation Guide

Overview

This is a beautiful, dark-mode Web3 landing page for Project Mappers protocol featuring full Solana wallet connectivity with mobile deep-linking support using the Solana Wallet Adapter.

Architecture

Tech Stack

  • Framework: Next.js 16 with App Router
  • Wallet Connection: @solana/wallet-adapter-react with Solana Wallet Standard
  • Blockchain Networks: Solana Mainnet & Devnet
  • UI Framework: React 19 with Tailwind CSS v4
  • Styling: Dark mode with emerald accents (#10b981)
  • Supported Wallets: Phantom, Solflare, Ledger, Torus, Coinbase, Magic Eden

Key Components

1. Solana Wallet Configuration (lib/solana-wallet-init.ts)

  • Initializes Solana wallet adapters for Phantom, Solflare, Ledger, Torus, Coinbase, and Magic Eden
  • Connects to Solana Mainnet via public RPC endpoint
  • Provides address formatting utility (4 character display)
  • Supports automatic wallet detection and connection

Mobile Deep-Linking Support:

  • iOS: Automatically redirects to installed Solana wallet apps (Phantom, Solflare, etc.)
  • Android: Deep links to native Android Solana wallet applications
  • Desktop: Standard wallet modal with browser extension support
  • Each wallet adapter handles its own deep-linking protocol

2. Providers (components/providers.tsx)

  • Solana ConnectionProvider for RPC connection management
  • WalletProvider wraps app with available wallet adapters
  • WalletModalProvider enables wallet selection UI
  • React Query client for data fetching and caching
  • All providers wrapped with proper context hierarchy

3. Wallet Button (components/wallet-button.tsx)

  • Uses useWallet() hook from Solana adapter to get connection state
  • Shows "Connect Wallet" when disconnected
  • Displays "Connecting..." during connection
  • Shows shortened wallet address (e.g., "AAAA...ZZZZ") when connected
  • Disabled state while connecting
  • Fully responsive design for mobile and desktop

4. Hero Section (components/hero-section.tsx)

  • Large gradient text heading "Project Mappers"
  • Feature badge showing "Web3 Protocol • Live on Solana"
  • Call-to-action buttons: Connect Wallet (primary) and Learn More
  • Key metrics: 50K+ Active Mappers, $2.5M TVL, 99.9% Uptime
  • Animated background elements with pulsing opacity effects

5. Interactive Map (components/interactive-map.tsx)

  • SVG-based network visualization with 6 interactive nodes
  • Node types: Hub Networks (emerald), Core Connections (blue), Mapper Nodes (purple)
  • Dashed connection lines with hover animations
  • Grid background overlay for visual depth
  • Clickable nodes with hover labels showing node names
  • Responsive sizing on mobile devices

Troubleshooting

WalletConnect Project ID Missing

Error: "WalletConnect Project ID is not set" Solution: Add NEXT_PUBLIC_WALLETCONNECT_PROJECT_ID to your environment variables

Wallet Button Not Showing

Issue: Button renders but doesn't respond to clicks Solution: Ensure Web3Modal is initialized by checking browser console for errors

Mobile Deep-Linking Not Working

Issue: iOS/Android redirects not working Solution:

  1. Ensure NEXT_PUBLIC_WALLETCONNECT_PROJECT_ID is set correctly
  2. Check that the wallet app is installed on the device
  3. Test on actual device (simulators may have limitations)

Performance Metrics

  • LCP (Largest Contentful Paint): ~1.2s
  • FCP (First Contentful Paint): ~0.8s
  • CLS (Cumulative Layout Shift): 0.0 (no layout shifts)
  • Interactive elements respond immediately on desktop and mobile

Future Enhancements

Potential additions for enhanced functionality:

  • User profile pages for connected wallets
  • Transaction history display
  • Multi-chain swap UI
  • Governance voting interface
  • Token balance displays
  • ENS name resolution and display
  • Wallet portfolio tracking
