🏆 Track: RWA / RealFi

Unlocking the $ trillion real-world asset market with AI verification, compliance-ready tokenization, and native yield distribution.

🎯 The Problem We're Solving

The $ Trillion Real-World Asset (RWA) market faces critical challenges:

📄 Manual Verification Crisis - Takes 3-14 days and costs $10-$1000 per document
🚫 Centralized Trust Issues - Relies on intermediaries and paper trails
💸 Illiquidity Trap - No native venues for trading tokenized assets
⚠️ Fraud Risk - $50 billion lost annually to document fraud

A.R.I.A. leverages Mantle's high-performance modular L2 to eliminate these bottlenecks.

💡 Our Solution

A.R.I.A. is a complete end-to-end protocol that transforms real-world documents into verified, liquid, tradeable NFTs on Mantle Network. We deliver:

🚀 Getting Started

Prerequisites

Node.js 18+ & Python 3.9+
Mantle Wallet (MetaMask configured for Chain ID 5003)

Installation

1. Clone & Setup

git clone https://github.com/Nihal-Pandey-2302/ARIA-Mantle.git
cd ARIA-Mantle

2. Install Dependencies

# Backendcd backend
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt

# Frontendcd ../frontend
npm install

3. Deploy to Mantle Testnet

cd ../contracts

npx hardhat run scripts/deploy.js --network mantleTestnet

4. Run Application

# Starts both Backend (Port 5001) and Frontend (Port 5173) components
./run.sh

🆕 Mantle Hackathon Features (Tier 1 & 2)

1. Native KYC/AML Integration 🆔

A.R.I.A. on Mantle includes a strict compliance layer.

How it works: Users self-attest via the KYCGate component.
On-Chain: The AriaNFT contract checks kycStatus[msg.sender] before allowing any minting transaction.
Privacy: Identity docs are hashed via IPFS (simulated for demo).

2. RWA Yield Distribution 💸

Real-world assets generate cash flow. A.R.I.A. makes it claimable on-chain.

YieldDistributor: A pull-payment contract where asset managers deposit yield.
Instant Claims: NFT holders visit the Yield Dashboard to withdraw their share in $MNT or $ETH.

3. Oracle-Powered Hybrid Pricing 🔮

Sellers can list assets in USD, preventing crypto-volatility risk.

MockOracle: We deployed a custom Oracle on Mantle Testnet since Chainlink feeds are Mainnet-only.
Dynamic Conversion: Buyers pay the real-time $MNT equivalent of the USD price.

🧪 Testing Guide

Manual Flow

Connect Wallet: Switch to Mantle Testnet.
KYC Check: Click "Verify Identity" in the header. (Required to Mint)
Upload: Select "Invoice" and upload a PDF.
Mint: Create your verifiable RWA NFT.
Yield: Go to /yield to see simulated earnings from your asset.

🚀 Progress During Mantle Review Hackathon Phase 1: Migration & Infrastructure We started by migrating the core ARIA protocol to Mantle Sepolia Testnet. Challenge: Existing codebase was tuned for legacy EVM chains with different block times and gas logic. Solution: Updated hardhat.config.js to target Chain ID 5003. We initially faced stability issues with public RPCs (DRPC/Omnia) resulting in 429 Too Many Requests. Fix: Switched to the official rpc.sepolia.mantle.xyz endpoint and implemented a Multi-Provider Fallback Strategy in the frontend to ensure uptime during the demo. Phase 2: The "Gas" Mystery & L2 Adaptation Mid-development, we hit a critical wall: Transactions were failing with an obscure Internal JSON-RPC error. Investigation: Logs showed intrinsic gas too low. Mantle, being an L2, requires slightly different gas estimation for L1 rollups. Breakthrough: We rewrote the backend blockchain_service.py to use Dynamic Gas Estimation with a 20% safety buffer and a strict 100M Gas Fallback, ensuring high-compute transactions (like AI data storage) never fail on the rollup. Phase 3: Native Compliance Layer We aimed for Tier 1 Regulatory Compliance. Implementation: We coded AriaNFT.sol with a onlyKYCVerified modifier. The Bug: During testing, minting suddenly stopped working. We realized the contract was too secure—it was rejecting our own test wallets! The Feature: We turned this bug into a feature by building the KYC Gate UI. Now, users must physically click "Verify Identity", sign a message, and get an on-chain Verified badge before they can interact with the protocol. Phase 4: AI & Yield Logic AI Integration: Successfully connected Groq Llama 3.3 to analyze PDF invoices in under 2 seconds. Yield Dashboard: We encountered a frontend crash because the YieldDistributor contract lacked an enumeration method. Hackathon Fix: Instead of redeploying and breaking state, we implemented an Event Indexing Strategy in React. The dashboard now reconstructs a user's portfolio by scanning Transfer events on the Mantle blockchain, providing a real-time view of their RWA earnings. 🏆 Final Status 100% Complete & Deployed. ARIA is now a fully functional, compliance-ready RWA platform running on Mantle Testnet, capable of turning a PDF into a yield-bearing asset in less than 30 seconds.
