WrapSell

A decentralized banking system that uses Pokémon TCG cards as collateral to mint stablecoins, creating a fiat-free currency backed by trading card value.

Overview

WrapSell transforms your Pokémon TCG card collection into a digital asset that can be used as collateral for minting stablecoins. The system ensures that each token is backed by real card value.

System Architecture

The project is divided into three main components:

1. Frontend

• User interface for managing card collections
• Real-time card value tracking
• Token minting and burning interface
• Collection management dashboard

2. Backend

• Centralized card database
• Market value tracking system
• Price data aggregation

3. Smart Contracts

• Chainlink integration for price feeds
• Collateral validation system

How It Works

1. Collection Management

   • Users register their Pokémon TCG cards
   • System tracks current market values
   • Collection value is calculated in real-time

2. Token Minting Process

   • Smart contract checks collection value via Chainlink
   • System validates collateral sufficiency
   • New tokens are minted based on available collateral
   • Only authorized addresses can execute minting

3. Value Tracking

   • Real-time price updates
   • Automated collateral verification

User Flow Example

1. Initial Setup

   • User connects his wallet to WrapSell
   • He creates an account and verifies his identity

2. Card Registration

   • User submits their physical card to WrapSell's secure facility
   • Card is stored in our secure vault
   • Digital representation is created in our system
   • User receives a digital certificate of ownership

3. Collateralization Process

   • Smart contract receives card value from Chainlink
   • System calculates available collateral (e.g., 80% of card value = $400)
   • User can now mint up to $400 worth of WrapSell tokens

4. Token Minting

   • User requests to mint 200 WrapSell tokens
   • Smart contract verifies:
     • Card value is sufficient
     • User's wallet is authorized
     • Collateral ratio is maintained
   • Tokens are minted and sent to User wallet

5. Using WrapSell Tokens

   • User can now use his tokens like any other stablecoin
   • He can transfer them to other users
   • Use them for purchases
   • Trade them on DEXs

6. Token Burning

   • When User wants to retrieve his card
   • He burns his WrapSell tokens
   • Smart contract verifies the burn
   • Card ownership is transferred back to User
   • Physical card is returned to User

7. Value Updates

   • System continuously monitors card market values
   • If card value increases, User can mint more tokens
   • If value decreases, system may require additional collateral

This process creates a secure, transparent system where physical card value is transformed into digital assets while maintaining the security of the original collateral.
