🏴‍☠️ Architecture

This document introduces the overall architecture design of the ArtFlip platform.

System Architecture Overview

ArtFlip adopts a decentralized architecture, implementing NFT issuance, trading, and liquidity management based on smart contracts.

Core Components

1. Smart Contract Layer

Factory Contract

• Responsible for creating and managing NFT projects
• Handles project initialization parameters
• Manages project registry

ArtFlip Contract

• Implements the Bonding Curve algorithm
• Handles NFT minting and trading
• Manages trading pool and liquidity

Registry Contract

• Maintains project registration information
• Provides project query interfaces
• Manages project metadata

Trade Contract

• Handles NFT buy and sell transactions
• Calculates dynamic prices
• Manages trading pool

FeeVault Contract

• Manages platform fees
• Handles royalty distribution
• Fee withdrawal and distribution

2. Cross-chain Components

ZetaChain Integration

• Implements cross-chain NFT transfers
• Supports multi-chain interactions
• Cross-chain message passing

Superchain-ERC721 Standard

• Unified cross-chain NFT standard
• Enables seamless experience within the SuperChain ecosystem

3. Frontend Application Layer

Web Interface

• User interaction interface
• Wallet connection
• Trading operation interface

API Services

• Backend API services
• WebSocket gateway
• Real-time data push

4. Data Layer

The Graph Subgraph

• Indexes on-chain data
• Provides GraphQL query interfaces
• Real-time data synchronization

Technology Stack

Smart Contracts

• Solidity: Primary programming language
• Hardhat/Foundry: Development framework
• OpenZeppelin: Secure contract library

Frontend

• Next.js: Web application framework
• React: UI library
• Wagmi: Ethereum React Hooks

Backend

• NestJS: Node.js framework
• WebSocket: Real-time communication

Data Indexing

• The Graph: Decentralized indexing protocol

Data Flow

NFT Minting Flow

1. User initiates minting request through frontend
2. Frontend calls smart contract
3. Bonding Curve algorithm calculates price
4. User confirms and pays
5. NFT minting completed
6. Events triggered, Subgraph indexes data
7. Frontend updates display

NFT Trading Flow

1. User selects NFT to sell
2. Smart contract calculates selling price
3. NFT enters trading pool
4. Other users can purchase directly
5. Transaction completed, royalties automatically distributed
6. Data synchronized and updated

Security Mechanisms
