TFN Proof of Growth explores a simple idea: capture a meaningful childhood moment and connect it to a contribution toward the child’s future. A parent can preserve a drawing or memory in a private, parent-controlled gallery associated with an existing Tooth Fairy Network vault. The hackathon project develops the capture-to-vault experience around Ray-Ban Meta glasses and a phone companion.

Tooth Fairy Network is an existing family gifting product; the entire platform was not built during this hackathon. The new work focuses on the capture, review and contribution experience. The web implementation distinguishes a saved photo from a pending or confirmed contribution, shows the child’s vault balance separately from parent contribution funds, and requires adult review before a contribution.
