The Lottery dApp is a decentralized application for conducting transparent and secure lottery-based sales of high-value assets such as real estate and cars. Users can buy lottery tickets using cryptocurrency, and winners are selected randomly through verifiable smart contracts.
2. Objectives:
Enable users to sell and purchase properties or cars through lottery-style mechanisms.
Ensure transparency, security, and fairness using blockchain technology.
Comply with legal regulations and integrate KYC/AML procedures.
Establish a scalable affiliate model for integration with marketplaces and classified websites.
3. Functional Requirements:
3.1 User Roles:
Admin:
Manage platform operations.
Approve asset listings and monitor transactions.
Set ticket limits and manage prize pools.
Oversee affiliate marketplace partnerships and commission models.
Seller:
Submit property or car listings for lottery sales.
Define minimum ticket requirements.
Buyer/Participant:
Purchase lottery tickets.
Verify identity for KYC compliance.
Claim winnings if selected.
Marketplace Partner:
Integrate the lottery dApp as an addon to their platform.

3.2 Core Features:
Listing Management:
Sellers can list properties and cars with relevant details (location, images, value, etc.).
Define ticket pricing and quantity.
Ticket Purchase:
Users can purchase tickets using supported cryptocurrencies.
Generate unique NFT-based tickets linked to each sale.
Random Winner Selection:
Implement decentralized random number generation using Chainlink VRF.
Smart contract automatically selects a winner once all tickets are sold.
Payment Handling:
Funds are held in an escrow contract.
Smart contract distributes funds to the seller after the lottery concludes.
Affiliate and Commission Management:
Integrate with external marketplaces and classified listing sites.
Automate commission calculations and disbursements.
Provide tracking dashboards for affiliates to monitor sales performance.
KYC/AML Integration:
Partner with a third-party KYC provider for identity verification.

Automated ticket minting, prize distribution, and refund handling.
Notifications:
Email and in-app notifications for important events (ticket purchase confirmation, lottery result announcements).
Transaction Records:
Immutable ledger for ticket sales and lottery results.
4. Smart Contract Design:
Language: Solidity
Functions:
Ticket Purchase
Winner Selection
Escrow Management
Refunds
Prize Distribution
Affiliate Commission Distribution
Security:
Use OpenZeppelin libraries for secure contract development.
Implement reentrancy and overflow protection.
5. Blockchain Network:
