Description
Project Name:
Zaap – No cash. No cards. Just Zaap.
Vision Statement:
Zaap empowers teenagers with financial independence while giving parents complete oversight — all through a privacy-first, Web3-native, and non-KYC digital payment system. Zaap bridges the gap between digital-native teenagers and responsible financial behavior.
Problem We Solve:
Lack of Digital Financial Tools for Teens: Traditional banks are too rigid or complex for minors, often requiring full KYC and adult co-signers.
Overdependence on Cash or Parent Cards: Teens lack autonomy in spending and learning money management.
Privacy Concerns with Banks: Minors are forced to share identity details with third parties.
No Real-Time Parental Oversight: Parents can’t track or limit teen spending effectively.
Web2 Limitations: Existing systems are centralized, outdated, and lack smart programmability.
