Technical Stack Breakdown

Frontend (User Interface):
  • Frameworks: React.js with Tailwind CSS for responsive design.
  • Wallet Integration: Wagmi and viem for seamless wallet connections; ConnectKit for user-friendly wallet UI.
  • Content Delivery: IPFS for decentralized storage of video previews and metadata.
  • User Interaction: Infinite scroll content feed with filters for Popular, Recent, and Bonded memes.
Backend / Middleware:
  • Server: Node.js with Express for handling API requests.
  • Database: PostgreSQL for managing user sessions and social metadata.
  • Storage: IPFS (via Pinata) for storing short-form video files and NFT metadata.
  • Indexing: Subgraph or custom indexer to track:
    • Meme NFT creation
    • Bonding volume and holders
    • FOLK reward distribution
    • Meme graduation status
Smart Contracts (Solidity on Arbitrum):
  • Genesis.sol: Facilitates the creation of ERC-721 meme NFTs by creators.
  • BondingCurve.sol: Implements ERC-20 bonding tokens for each meme, utilizing dynamic pricing functions.
  • Graduation.sol: Manages the transition of meme tokens upon reaching specific thresholds (likes, bonding volume).
  • FOLK.sol: Serves as the platform-wide utility token, earned through Like-to-Earn and Trade-to-Earn mechanisms.

​
Integration of Arbitrum Technologies

To enhance Folktizen’s capabilities and align with Arbitrum’s ecosystem, the following technologies are integrated: a. Arbitrum Stylus:
  • Description: Allows developers to write smart contracts in traditional programming languages like Rust and C++, interoperable with existing Solidity contracts.
  • Benefit: Enables high-performance, resource-intensive applications with improved efficiency and lower gas costs.
  • Reference: Arbitrum Stylus
b. Arbitrum Orbit Framework:
  • Description: Simplifies application development for Layer-3 (L3) networks, allowing for personalized AppChains.
  • Benefit: Enables Folktizen to create dedicated chains with tailored privacy settings, permissions, and governance mechanisms.
  • Reference: Arbitrum Orbit
c. Biconomy Integration:
  • Description: Provides plug-and-play APIs for gasless transactions and simplified user experiences.
  • Benefit: Users can interact with Folktizen without worrying about gas fees, enhancing accessibility for non-crypto natives.
  • Reference: Biconomy Gasless Transactions on Arbitrum
d. Moralis APIs:
  • Description: Offers comprehensive APIs for accessing on-chain data, including token data, transactions, NFT data, and more.
  • Benefit: Accelerates development and deployment of Folktizen by providing essential data and reducing development time.
  • Reference: Build on Arbitrum with Moralis

​
Deployment & Scalability

  • Deployment: All smart contracts are deployed on Arbitrum One, leveraging its low gas fees and high throughput.
  • Scalability: The architecture supports millions of daily interactions, ensuring a responsive user experience.
  • Security: Utilizes Ethereum’s Proof of Stake consensus mechanism through Arbitrum, ensuring robust security.
