Implement NFT-Based Market Participation

[Bruno755]

Overview

Create NFT market access tokens enabling NFT-holder discounts, voting power, and exclusive market access. NFTs represent platform membership tiers.

Scope

In scope:

• NFT minting (tier 1-3: basic, VIP, elite)
• Fee discount tiers (10%, 25%, 50% respectively)
• Bonus voting power (1x, 2x, 5x)
• Exclusive market access (beta markets for elite)
• NFT transfer/selling support
• Tier upgrade mechanism

Out of scope:

• NFT marketplace integration
• Rental/leasing mechanisms

Acceptance Criteria

• 3 NFT tiers with clear benefits
• Fee discounts active in AMM
• Voting power reflected in governance
• Exclusive markets restricted by NFT tier
• NFTs tradeable on OpenSea/LooksRare
• Tier downgrade handled correctly

I would like to take on this issue. With my experience in blockchain-focused products, I can deliver a scalable NFT membership system that is secure, intuitive, and aligned with the project's goals.

My implementation will include:

• Three NFT membership tiers (Basic, VIP, Elite) with the specified fee discounts, voting power, and access permissions.
• Smart contract logic for tier upgrades, transfers, and proper downgrade handling.
• Integration of fee discounts into the AMM and governance voting weights.
• Access control for exclusive beta markets based on NFT tier.
• Full ERC-721 compliance to ensure NFTs are tradeable on OpenSea and LooksRare.

I will focus on clean architecture, comprehensive testing, and clear documentation to ensure all acceptance criteria are met while keeping the solution maintainable and easy to extend in future releases.

Resolved by PR #108 — NFTTier.sol (3 tiers, fee discounts, voting power, elite access), AMM.sol (NFT fee discount integration), and Market.sol (exclusive market gating) have all been implemented and are ready for review.
