ReLoop: Resale-Native RWA Marketplace on Mantle

Mantle Global Hackathon 2025 | RWA / RealFi Track
BUILT ON MANTLE NETWORK

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

EXECUTIVE SUMMARY

ReLoop is a resale-native Real World Asset (RWA) marketplace that transforms secondary markets into continuous value loops, starting with used cars.

Unlike traditional resale platforms where value ends at the point of sale, ReLoop introduces programmable resale economics — enabling resale profits to be automatically shared with previous owners across multiple ownership generations, without penalizing the current seller.

Built on Mantle’s modular Ethereum stack, ReLoop leverages low fees and EVM compatibility to enable trustless multi-party settlement, transparent ownership history, and scalable real-world asset tokenization.

Track Alignment:
RWA / RealFi (primary) + DeFi & Composability (secondary)

Status:
Functional MVP | Marketplace UI | Smart contract–based resale logic | Mantle testnet / mainnet-ready

PROBLEM → SOLUTION

Problems in Traditional Resale Markets (Used Cars as Entry Point)

• Zero Incentives for Early Buyers
Early buyers take higher risk but earn nothing from later resales

• Value Leakage
Secondary market liquidity benefits only the final seller

• Opaque Ownership History
Trust relies on intermediaries and fragmented records

• Static Asset Design
Assets are not designed for repeated, programmable resale

ReLoop Solution

• Resale-Native Assets
Each asset is tokenized with embedded resale logic from day one

• Backward Value Flow
Resale profits automatically flow to previous owners

• Seller-Protected Economics
Current sellers are never penalized

• On-Chain Transparency
Ownership, resale history, and payouts are verifiable on-chain

Market Opportunity:
• Global used car resale market: $1.5T+
• Initial focus: high-liquidity secondary car markets
• Expansion-ready for real estate, equipment, commodities, IP

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

TECHNICAL INNOVATION

1. Programmable Resale Economics (Core Innovation)

• Each RWA NFT embeds:

• Maximum resale depth (e.g. 3–5 generations)

• Profit split configuration
  • On every resale:

• Seller receives primary proceeds

• Previous owners automatically receive defined shares
  • Fully enforced by smart contracts — no intermediaries

2. RWA Tokenization Architecture

• ERC-721 / ERC-1155 based asset representation
• Immutable ownership history
• Resale logic executed atomically during settlement

3. Mantle-Optimized Execution

• Low gas fees enable:

• Multi-party payouts per transaction

• Frequent secondary market activity
  • Native EVM compatibility simplifies developer tooling
  • Mantle DA used for asset metadata and history storage

SMART CONTRACTS (MANTLE NETWORK)

Contracts include:
- ReLoopRWA (NFT Contract)

Address: 0xaA4886d00e3A22aB6f4b5105CC782B1C29c3d910

This is where your car becomes a digital asset. When you mint a car on ReLoop, this contract creates a unique NFT (Non-Fungible Token) that represents your real-world vehicle.

What it does:

- Mints your car as an NFT - Converts your car listing into a tradeable digital asset

- Stores car details - Links to images, description, and specifications on IPFS

- Tracks ownership history - Records every owner and their purchase price

- Sets profit sharing rules - Defines how profits are split among previous owners when resold

• ReLoopMarketplace

Address: 0x003f586c9Dc9de4FeE29c49E437230258cb4cA9E

This is the marketplace where cars are bought and sold. It handles all transactions and automatically distributes profits to previous owners.

What it does:

- List for sale - Put your car NFT up for sale at your chosen price

- Buy cars - Purchase listed cars using USDC

- The Loop Magic - When a car sells for profit, the contract automatically sends earnings to all previous owners

- Platform fees - Collects a small fee to keep the platform running

Network: Mantle Network
Deployment: Testnet / Mainnet-ready
All contracts designed for verification and public audit.
