RealFlow Studio

AI-Driven No-Code RWA Marketplace Builder - Build custom marketplaces for Real-World Assets in minutes, powered by AI.

🌟 Overview

RealFlow Studio enables non-technical users (real estate agents, artists, entrepreneurs) to create and launch custom marketplaces for tokenized RWAs like real estate, art, and commodities. Users can:

Drag-and-drop to design marketplace UI
Tokenize assets with AI-generated smart contracts
Deploy to multiple EVM chains (Polygon Amoy and Avalanche Fuji testnets)
