Built for MetaMask Card Dev Cook-Off
Spend2Earn is a smart DeFi automation platform that transforms MetaMask Card spending into real financial utility.
🧩 Problem:
Cashback is often idle. Manual yield hunting is complex. Retail users can’t access credit from their spending.
🚀 Solution:
Every MetaMask Card transaction earns 2.5% cashback, which is auto-staked into cross-chain DeFi vaults. These vaults grow in value, unlock trustless credit lines, and allow automated repayments — all simulated through a seamless user journey.
🔧 Key Features:
Card Spending Simulator → Cashback → Vault Growth
Auto-stake via LI.FI Routing (simulated)
Vault-backed Borrowing (60% LTV)
Repayment from vault yield or wallet
Badge Tiers (Verified, Silver, Gold) unlock perks
USDC routing via Circle CCTP
7-tab SPA with closed DeFi journey
📊 Built With: Next.js, Tailwind CSS, Zustand, MetaMask SDK, LI.FI SDK, Circle CCTP, FastAPI (dummy backend)
✅ Track Fit:
