Reimagining Groupon with tradable NFT coupons on Solana
$5,000 USDC + Gen3 Monke NFT (12-month locked)
🥇 Superteam Earn Winner | 🌏 Built in Indonesia | 🕌 Built with Ihsan
Traditional coupon platforms waste value.
Groupon pioneered local deals—but the model is broken:
- 🗓️ Expiration Waste - Unused coupons lose 100% value after expiry
- 🔒 Non-Transferable - Can't sell/gift coupons you won't use
- 📉 Fixed Pricing - No market dynamics, merchants can't adjust
- 💸 Lost Money - Consumers can't recoup value from unused deals
- 🏪 Inflexible - Merchants locked into rigid discount campaigns
Result: $billions in unrealized value, frustrated users, limited merchant control.
Turn coupons into liquid assets.
Web3 Deal Discovery transforms local deals into Solana NFTs with:
- 🎟️ NFT Coupons - Every deal is a unique, ownable NFT
- 💰 Secondary Market - Trade coupons on-chain, recover value
- 🔄 Dynamic Pricing - Coupon value adjusts based on demand
- 🏪 Merchant Control - Real-time campaign management dashboard
- ⛓️ On-Chain Verification - Tamper-proof redemption tracking
- 🌍 Global Liquidity - Anyone can buy/sell local deals
Tagline: "Your unused coupon is someone else's bargain."
