Description

CoinTown is where fractionalized property investment meets social gaming. Instead of static dashboards and complex spreadsheets, we turn tokenized RWAs into a vibrant, multiplayer 3D board game. Players compete to build the most valuable real-world portfolio, collecting yields (rent) and trading assets in real-time, all secured by the Mantle blockchain.

Key Features:

Gamified RWA Investment: Each tile on the 3D board represents a fractionalized Real-World Asset (e.g., tokenized real estate or debt). Landing on a tile isn't just a game move—it's a friction-less opportunity to invest in yielding assets.
On-Chain Compliance: Integrates a custom KYCRegistry and Identity verification system to ensure that RWA ownership is compliant while remaining completely invisible to the user's gaming experience.
Zero-Friction Onboarding: Utilizing ERC-4337 Account Abstraction, users sign in with Google OAuth. A smart contract wallet is automatically generated, removing the need for seed phrases or manual gas management.
Hybrid Real-Time Engine: High-fidelity 3D graphics (React Three Fiber) and real-time multiplayer synchronization (WebSockets) provide a premium gaming feel, while critical ownership changes are settled on Mantle.

Progress During Hackathon

During this hackathon, we built a full-stack gamified RWA pipeline: Smart Contracts: Deployed a KYCRegistry for compliant on-chain identity and a modular MyNFT contract for RWA representation on Mantle Sepolia. Account Abstraction: Implemented a custom ERC-4337 factory and SimpleAccount logic to enable instant Google Login for non-crypto users. 3D Game Engine: Developed a high-performance 3D board using React Three Fiber, featuring dynamic model loading and smooth player interpolations. Backend Sync: Built a Node.js WebSocket server to handle multi-player rooms, real-time dice-roll simulations, and game-state synchronization."

Fundraising Status

Status: Pre-seed / Bootstrapped. (Currently an early-stage hackathon project focused on demonstrating the viability of gamified RWA interaction.)
