sui_flash::profile — On-Chain Flash-Card Manager Sui Overflow Hackathon Submission | Built on Sui

---

🚀 Project Overview

SuiFlash is a lightweight, on-chain flashcard application built on the Sui blockchain. It empowers users to create, own, and study digital flashcard collections directly from their Sui wallet. No centralized servers, no passwords, and no middlemen, SuiFlash lets users:

• Self-register on-chain and manage their own profile object
• Create named collections of flash cards (decks)
• Add individual flash cards (front & back text) into those decks
• Store all user data immutably via Move dynamic fields and tables

By making every deck and card a first-class Sui object, SuiFlash demonstrates how on-chain study tools can be built with strong ownership guarantees, native transferability, and transparent state evolution.

🎯 Key Features

1. User Registration

   • Single ProfileManager singleton tracks which addresses have customized profiles
   • Each new registrant receives a unique UserProfile object, embedding their own UserData

2. Dynamic Field Storage

   • Per-user data (total decks, total cards, deck metadata) lives in a dynamic field on your UserProfile
   • Clean separation between on-chain objects and user-scoped tables

3. Deck Creation

   • create_new_collection lets you name your deck (e.g. “Biology 101”)
   • New FlashCardCollection object is minted and transferred to your address

4. Card Minting

   • add_flash_card creates individual FlashCard objects with front/back text
   • Cards are stored in the deck’s internal table, and deck counts auto-increment

5. Pure Move-Native Logic

   • All validation, error handling, and state updates happen within Move entry functions
   • No off-chain components needed to run or test basic flows
