📌 Overview NexusRWA is a production-grade, end‑to‑end platform for tokenizing real‑world assets (RWAs) on the Ethereum blockchain. It bridges traditional finance (TradFi) and decentralized finance (DeFi) by enabling compliant, secure, and liquid digital representation of physical assets such as real estate, bonds, commodities, and more.
This project demonstrates advanced Solidity development, modern Web3 architecture, compliant token standards, and a full‑stack dApp with a seamless user experience.
✨ Features 🔗 Smart Contracts (Solidity) ERC‑3643 Compliant Token – Built-in KYC/AML, transfer restrictions, identity registry, and blacklisting. Token Factory – Deploy new RWA tokens with a single transaction. Vault & Yield Distribution – Pool stablecoins, mint shares, and distribute yield automatically. Chainlink Oracle Integration – Real‑time price feeds for accurate asset valuation. Access Control – Role‑based permissions (Admin, Minter, Compliance, Manager). Security – ReentrancyGuard, Pausable, and comprehensive access control.
🚀 Backend (Node.js + TypeScript) REST API – Token management, KYC verification, transaction history, and analytics. Prisma ORM – PostgreSQL database with clean, type‑safe models. Ethers.js Integration – Interact with deployed smart contracts. Scalable Architecture – Service‑oriented design with clear separation of concerns.
🎨 Frontend (Next.js + Wagmi) Modern Dashboard – Built with Next.js 14, TailwindCSS, and TypeScript. Wallet Integration – Connect via MetaMask, WalletConnect, or any injected wallet. Token Management – Buy, sell, stake, and view yield in real time. Responsive Design – Optimized for desktop, tablet, and mobile.
🛠️ DevOps & Tooling Hardhat – Smart contract compilation, testing, and deployment. Foundry – Advanced fuzzing and invariant tests (optional). Docker Compose – One‑command full‑stack deployment. CI/CD Ready – Easily integrate with GitHub Actions or similar.
