Title Suggestion: Decentralized RWA Token Sale System on Quorum (QIE) | Full Smart Contract Demo
Welcome to the full demonstration of my Decentralized Real-World Asset (RWA) Token Sale System!

This project showcases a secure, end-to-end solution for tokenizing an asset (TVS Token V2) and automating its sale using the native currency (QIE) of the blockchain environment.
The Problem Solved
Traditional asset sales are slow and centralized. This project solves the need for a trustless, instant, and automated marketplace where RWA tokens can be securely exchanged for payment on-chain, eliminating counterparty risk.
Key Technical Achievements & Architecture
My solution uses a best-practice, two-contract architecture for maximum security and separation of concerns:

TVS Token V2 (The Asset): An upgraded ERC-20 contract that represents the tokenized asset and manages supply.

RWA_Sale_Contract (The Logic): Acts as the secure, automated cash register.

Core Functionality Demonstrated in Video:

Access Control: Granting the Minter Role to the Sale Contract, ensuring only the logic contract can create new tokens.

Atomic Purchase (buyAndMint): The core function that guarantees, in a single transaction, that payment (QIE) is collected AND tokens are minted and instantly transferred to the buyer.

Security Guarantee: The system is all-or-nothing—if the minting fails for any reason, the entire payment reverts, protecting the user.

Proof of Concept: The successful transfer of the newly minted TVS tokens between two separate user accounts.
Built With
Solidity: For all smart contract logic.

Remix IDE: Development and deployment environment.

OpenZeppelin Contracts: For implementing the ERC-20 standard and access control.

MetaMask: For wallet and transaction management.
