Crypto-Only Digital Vouchers Marketplace

2-User System:
-Registration via email.
-Basic profile, transaction history linked to wallet address.
3-Listing Management:
-Sellers post vouchers/services with title, description, category (e.g. Steam, Amazon, Xbox) and fixed USDT price.
-Bulk upload of listings for sellers.
4-Security & Trust:
-Fraud detection (e.g. duplicate code checks, suspicious activity alerts).
-User reviews/ratings to build reputation.
5-Admin Panel:
-Real-time monitoring of all USDT transactions.
-Manage listings, user disputes, and blacklisting of suspicious wallets.
