NFT Treasury

Access Exclusive Content Through Gated NFTs

Comment

NFT Treasury Project Documentation

💡 Inspiration

Inspired by the idea of exclusive access through NFT ownership, I built a Web3 platform that restricts content to users who hold specific NFTs. The vision was to create a decentralized membership system where:

  • Exclusive Access: Only verified NFT holders can access premium content
  • Blockchain Verification: Using smart contracts for unhackable authentication
  • Token-Gated Experiences: Creating secure, community-driven access control
  • Decentralized Authentication: Moving beyond traditional centralized login systems

The project emerged from recognizing the fundamental problems with centralized membership platforms:

  • Single points of failure that can be hacked
  • Lack of cryptographic proof of ownership
  • Bypassable authentication systems
  • No transparent verification process

🎯 What it does

NFT Treasury is a comprehensive Web3 application that implements a tiered membership system based on NFT ownership:

Core Functionality:

  • Wallet Integration: Seamless connection via Rainbow Kit and MetaMask
  • NFT Verification: Real-time blockchain queries using Alchemy SDK
  • Tiered Access Control:
    • 🥉 Bronze Tier (1-2 NFTs): Access to 12 standard NFTs and basic features
    • 🥈 Silver Tier (3-4 NFTs): Premium NFTs, Discord access, priority minting
    • 🥇 Gold VIP (5+ NFTs): Exclusive collections, 30% discounts, analytics dashboard

Key Features:

  • Token-Gated Content: Premium galleries, exclusive NFT collections
  • Dynamic Pricing: VIP discounts for Gold tier members
  • Real-time Benefits: Instant activation via BitBadges webhooks
  • Multi-layer Security: Blockchain + BitBadges + Smart Contract verification
  • IPFS Integration: Decentralized metadata storage via Pinata
  • Community Features: Discord integration, VIP events, email notifications

🛠️ How we built it

Frontend Architecture:

  • React + TypeScript: Modern, type-safe UI development
  • Vite: Fast build tool and development server
  • Tailwind CSS: Responsive, utility-first styling
  • Rainbow Kit + Wagmi: Seamless Web3 wallet integration
  • Custom Hooks: useMembershipNFTs for NFT count tracking

Backend Infrastructure:

  • Node.js + Express: RESTful API server
  • Webhook System: Real-time benefit activation
  • Email Integration: Nodemailer for member communications
  • IPFS Storage: Pinata for decentralized file storage

Blockchain Integration:

  • Alchemy SDK: Reliable blockchain data queries
  • Smart Contracts: Custom ERC-721 minting contracts
  • Ethereum Sepolia: Testnet deployment for development
  • BitBadges API: Decentralized membership badge system

Key Technical Components:

// NFT Ownership Verification
export async function ownsAnyERC721(address: string): Promise<string[]> {
  const nfts = await alchemy.nft.getNftsForOwner(address);
  const erc721s = nfts.ownedNfts.filter(nft => nft.tokenType === "ERC721");
  return erc721s.map(nft => nft.contract.address);
}

// Membership Tier Logic
const membershipTiers = {
  Bronze: { minNFTs: 1, benefits: ['Website Access', 'Basic Minting'] },
  Silver: { minNFTs: 3, benefits: ['Discord Access', 'Premium NFTs'] },
  Gold: { minNFTs: 5, benefits: ['VIP Perks', '30% Discount', 'Exclusive Collections'] }
};
