This project is a Real-World Asset (RWA) Tokenization Platform built on Hedera Hashgraph, enabling the secure tokenization, listing, and trading of physical and financial assets such as Real Estate, Invoices, Commodities, Stocks, and Carbon Credits.

Using the Hedera Token Service (HTS), any real-world asset can be converted into fungible or non-fungible tokens with metadata secured on IPFS. Once minted, assets are automatically listed on the decentralized marketplace, allowing investors to buy shares using HBAR.

The platform also automates rental income and revenue distribution via a smart PaymentSplitter contract, ensuring that token holders receive proportional earnings based on real-time ownership. Enabled with role-based permissions, issuers can onboard assets, managers can submit revenue, and users can freely trade tokens, all with fast, scalable, and low-fee transactions powered by Hedera’s enterprise-grade infrastructure.

The platform is designed using a modular Web3 architecture:

🔹 Smart Contracts & Blockchain Layer

Network: Hedera Hashgraph (Testnet)

Tokenization: Hedera Token Service (HTS)

Smart Contracts: Solidity, deployed via Hardhat

IPFS: Pinata for asset metadata & images

Hashio RPC: For EVM-compatible interactions

Three main contracts: 1️⃣ Admin Contract — Role & platform management 2️⃣ Marketplace Contract — Custody-less asset listings and HBAR payments 3️⃣ PaymentSplitter Contract — Automated rental income distribution

Hedera native token IDs (0.0.xxxxx) and no token custody design increases security and compliance.

🔹 Frontend

Built with React 18 + TypeScript

Tailwind CSS and Framer Motion for UI/UX

MetaMask wallet integration with ethers.js

🔹 Backend

Node.js + Express

MongoDB for user profiles, asset metadata references, and listing history

JWT authentication, CORS security, rate-limited APIs

IPFS upload and contract service modules handle decentralized storage

🔹 Security Measures

Role-based permission controls

Reentrancy & input validation in contracts

Emergency marketplace pause

HTTPS + session security + validation middleware

🔹 Why Hedera?

✅ 10,000+ TPS performance

✅ Low fixed-fee token operations

✅ 3–5s finality

✅ Carbon-negative and enterprise-governed

✅ Native compliance controls built into HTS

This combination provides a production-ready foundation for institutional-grade asset tokenization with real-world utility and democratized access to global investments.
