ISSUE-003-CU03: Implement Real NFT Integration

[davidmelendez]

✨ Issue Request

Replace the NFT minting simulation with real integration to the LottoTicketNFT contract. Each ticket must generate an intransferible NFT.

📌 Description

Currently the system uses a simulation for minting lottery ticket NFTs. Real integration with the LottoTicketNFT contract is required so that each purchased ticket generates an intransferible NFT representing the user's participation.

🛠️ Steps to Reproduce (if applicable)

1. Purchase a lottery ticket
2. Verify that a real NFT is generated
3. Confirm that the NFT is intransferible
4. Validate that the NFT contains the selected numbers

🖼️ Screenshots (if applicable)

Not applicable - contract integration.

🎯 Expected Behavior

• Each purchased ticket must generate a real NFT
• The NFT must be intransferible (cannot be transferred to other wallets)
• The NFT must contain the selected lottery numbers
• The NFT must have correct metadata (date, numbers, etc.)
• The NFT must appear in the user's wallet

🚀 Suggested Solution / Feature Request

Phase 1: LottoTicketNFT Contract Analysis

• Review available functions in LottoTicketNFT
• Identify mint function for tickets
• Verify required parameters
• Confirm that the NFT is intransferible

Phase 2: Scaffold-Starknet Integration

• Add useScaffoldContractWrite hook for mint
• Connect with ticket purchase component
• Implement transaction handling
• Add loading states during mint

Phase 3: UI/UX Updates

• Show mint progress in real time
• Add NFT generation confirmation
• Display NFT metadata (numbers, date)
• Implement error handling

Phase 4: Testing and Validation

• Test NFT mint with valid numbers
• Verify that the NFT is intransferible
• Test with different number combinations
• Validate NFT metadata

📌 Additional Notes

• Priority: High - core system functionality
• Estimated time: 2-3 days
• Risk: Medium - contract integration
• Dependencies: LottoTicketNFT contract, scaffold-starknet hooks

Hi team 👋,

I'd love to work on this integration. I have 1.5 years of experience in smart contract development (Solidity ), along with frontend experience using TypeScript and Scaffold-Starknet.
Plan to Solve:

1. Review LottoTicketNFT contract to understand the mint function and ensure NFTs are non-transferable.

2. Integrate using useScaffoldContractWrite to mint the NFT when a ticket is purchased.

3. Update UI to show real-time mint progress, confirmation, and display NFT metadata (numbers, date).

4.Test the full minting flow, validate metadata, and ensure the NFT is intransferible.

This issue aligns with my strengths in smart contract integration and user-centric Web3 UI. I’ve previously built similar NFT-based proof systems and am confident in delivering clean, tested code.

Looking forward to contributing.
