FemPunk: Nushu

FemPunk NüShu is an innovative blockchain-powered collaborative art platform that combines daily canvas creation, NFT economics, and community-driven revenue sharing. The project creates a unique ecosystem where artists can contribute to daily collaborative artworks and earn revenue based on their contributions.

🎨 Core Concept The platform operates on a daily canvas system where:

Daily Canvases: New collaborative canvases are created every day at 00:00 UTC+8 Color NFTs: Users purchase color NFTs to contribute to the daily canvas Collaborative Art: Multiple contributors paint on the same canvas using their owned colors, and the theme of each day is a new Nüshu character Revenue Sharing: When canvases are minted as NFTs, revenue is distributed proportionally to contributors

🏗️ Technical Architecture Frontend (Next.js + TypeScript)
