Tech Stack

Frontend

  • React + Next.js (Web App)

    • Chosen for fast, SEO-friendly, and scalable front-end development.

    • Supports server-side rendering (SSR) for better performance on art galleries and NFT showcases.

    • Integrated with wallet connection libraries like Wagmi + RainbowKit for seamless Ethereum interactions.

    • Provides a sleek UI for users to browse, generate, and mint AI art.

  • React Native (Mobile App)

    • Ensures cross-platform availability (iOS + Android).

    • Users can mint, buy, or showcase AI art NFTs directly from their phone.

    • Push notifications for drops, auctions, and collaborations.

Backend

  • Node.js + Express

    • REST APIs & GraphQL endpoints to connect frontend with AI generation, NFT metadata, and blockchain.

    • Manages authentication, user sessions, and role-based access (artists, collectors, curators).

  • PostgreSQL (Database)

    • Stores user profiles, project metadata, auctions, bidding history, and transaction references.

    • Relational structure makes it easy to handle advanced queries (e.g., top-selling AI artists, trending collections).

  • Redis (Queue + Cache)

    • Used for real-time processing of AI art generation requests.

    • Stores temporary results like AI outputs before they are minted on-chain.

    • Improves performance for high-demand features like auctions and leaderboards.

Blockchain

  • Solidity + Hardhat (Smart Contracts)

    • Core contracts for minting, auctions, royalties, and governance.

    • Hardhat provides a robust testing environment with plugins for OpenZeppelin (security, upgradeability, ERC-721/ERC-1155).

    • Multi-chain deployment strategy (starting with Ethereum, extending to Layer 2 like Arbitrum/Polygon for lower gas fees).

  • OpenZeppelin

    • Pre-audited and secure implementation of token standards (ERC-20, ERC-721, ERC-1155).

    • Role-based access control for admin, curator, and treasury management.

    • Royalty standard compliance (EIP-2981).

Storage

  • IPFS / Filecoin

    • Ensures decentralized, censorship-resistant storage for AI-generated art.

    • Metadata (JSON files) pinned permanently to Filecoin via NFT.Storage or Pinata.

    • Guarantees that minted NFTs remain valid and immutable.

AI Integration

  • Replicate API

    • Provides an easy way to run multiple AI models (Stable Diffusion, ControlNet, etc.) on demand.

    • Used for real-time image generation with community-selected styles.

  • OpenAI (DALL·E, GPT Models)

    • DALL·E for prompt-to-image generation.

    • GPT models for AI Art Assistant (helps users craft prompts, titles, and descriptions for their NFTs).

  • Stable Diffusion APIs

    • Open-source model integration for fine-tuned AI art models (trained on specific artists, styles, or datasets).

    • Custom model marketplace: Artists can train/upload their own models and monetize them.

Infrastructure

  • Docker

    • Containerized deployment for backend, frontend, and AI services.

    • Guarantees consistent environments across dev, staging, and production.

  • GitHub Actions (CI/CD)

    • Automated testing for smart contracts and APIs.

    • Continuous delivery pipelines for fast deployment of new features.

  • Gnosis Safe (Treasury Management)

    • DAO/community treasury secured with multi-signature wallets.

    • Used for distributing funds from NFT royalties, artist rewards, and grants.
