Snap Coffee is Based

Snap Coffee is a social mini app and on-chain loyalty platform built on Base to onboard millions of new Web3 users by targeting one of the largest and most passionate global consumer segments: daily coffee drinkers, over 1 billion people worldwide.

We start with a simple, familiar action: taking a photo of your coffee. Every verified coffee purchase earns on-chain points, and after 10 coffees, users receive an NFT coupon for their 11th coffee, instantly redeemable at participating cafés.

The Problem

Traditional loyalty programs are broken:

Paper cards get lost, damaged, or forgotten 📄❌
Café owners lack reliable customer data and insights 📊❌
Loyalty isn't engaging — it's transactional and disconnected from the coffee culture ☕❌

The Solution

Using Base for low-cost, fast, and scalable transactions, Snap Coffee creates a geolocated, on-chain customer database enriched with demographic insights. This enables café owners to:

⚡ Track visits in real time
🎯 Understand customer behavior by location, time of day, and preferences
🚀 Run targeted marketing campaigns and personalized rewards

Sustainable Business Model

Snap Coffee generates revenue through:

💼 B2B SaaS subscriptions for cafés to access loyalty, analytics, and marketing tools
💳 Transaction fees for each redeemed NFT coupon
🎪 Brand sponsorships from coffee, equipment, and lifestyle companies

By fixing the loyalty gap and creating a shareable, gamified coffee culture, Snap Coffee drives mass adoption of Base, turning a daily habit into global on-chain engagement.

✨ Key Features

🛠️ CDP Technology Deep Dive

🤖 CDP Agent Kit Implementation

File: Backend/src/agents/reward-agent.ts

Our autonomous AI agent handles the complete coffee validation and reward cycle:

export class CoffeeRewardAgent {
  private agent: CdpAgent;
  private agentkit: CdpAgentkit;
  
  // GPT-4 Vision validates coffee photos autonomously
  async validateAndReward(params: {
    imageUrl: string;
    userAddress: string;
    venueName: string;
    // ... more params
  }): Promise<AgentResult>
}

Key Capabilities:

🧠 GPT-4 Vision Analysis: Validates coffee authenticity, venue matching, quality assessment
⚡ Autonomous Transactions: Directly distributes $BEAN tokens without manual intervention
🛡️ Fraud Detection: AI-powered spam and duplicate detection
🏆 Smart Rewards: Context-aware reward amounts (new venue bonuses, streak multipliers)

🏪 CDP Server Wallets Infrastructure

File: Backend/src/services/cdp-server-wallet.ts

Automated wallet infrastructure for every coffee shop:

export class CDPServerWalletService {
  // Creates dedicated wallet for each coffee shop
  async createStoreWallet(params: {
    storeName: string;
    storeId: string;
    city: string;
    state: string;
    placeId: string;
  }): Promise<StoreWalletResult>
  
  // Automated NFT coupon minting
  async mintStoreCoupon(storeWallet: Wallet, userAddress: string): Promise<MintResult>
}

Infrastructure Benefits:

🏦 Per-Store Wallets: Each coffee shop gets dedicated on-chain wallet
🎫 Automated NFT Minting: No manual intervention for coupon creation
📊 Revenue Analytics: Track redemptions, tips, engagement per store
⚡ Gas Optimization: Batch transactions and subsidized gas fees

🔗 MiniKit SDK Integration

File: FrontEnd/src/hooks/useMiniKit.ts

Seamless Farcaster experience with native Web3 UX:

export const useMiniKit = () => {
  // Native Farcaster wallet connection
  const connectWallet = useCallback(async () => {
    return await connectWallet();
  }, []);
  
  // USDC tipping with MiniKit
  const sendUSDCTip = useCallback(async (params: {
    toAddress: string;
    amount: string;
    creatorName: string;
  }) => {
    const { transactionId } = await tokenTransfer(transferParams);
    return { success: true, transactionHash: transactionId };
  }, []);
}

MiniKit Advantages:

🎯 Native Farcaster UX: Users never leave the familiar Farcaster environment
⚡ Instant Transactions: Base network enables sub-second transaction finality
🔄 Social Integration: Coffee posts automatically sync with Farcaster feed
💰 Embedded Tipping: Native USDC transfers without external wallet switching

💳 Enhanced Onramp Experience

File: FrontEnd/src/components/EnhancedOnrampWidget.tsx

Context-aware fiat-to-crypto conversion with coffee-specific UX:

const EnhancedOnrampWidget = ({ context }: { context: OnrampContext }) => {
  const tabs = [
    { id: 'tip', label: '☕ Tip Creators', description: 'Support coffee influencers' },
    { id: 'rewards', label: '🪙 Top Up Rewards', description: 'Buy more $BEAN tokens' },
    { id: 'wallet', label: '💰 Add to Wallet', description: 'General USDC purchase' }
  ];
  
  // Context-aware onboarding and amounts
  const getContextualAmounts = (context: string) => {
    switch (context) {
      case 'tip': return [5, 10, 25]; // Tip-appropriate amounts
      case 'rewards': return [25, 50, 100]; // Reward bundle amounts
      default: return [50, 100, 250]; // General wallet amounts
    }
  };
};

Enhanced Features:

📱 Contextual UI: Different interfaces for tipping, rewards, general wallet funding
🎯 Smart Amounts: Pre-configured amounts for different use cases
🔄 Onboarding Flow: Guided experience explains USDC, Base, and wallet concepts
✅ Success Integration: Seamlessly returns to intended action after purchase
