Defi - Coder Merchandise (DFM)
Project Overview Defi - Coder Merchandise (abv. DFM) is a blockchain-powered parcel and ecommerce distribution system designed for real-world merchants. It integrates IoT lockers, smart contracts, DeFi-based payment rails, and customer loyalty mechanisms to create a one-stop decentralized merchandise platform. This project reimagines software + hardware commerce into a formal blockchain parcel machine outlook, ensuring transparency, efficiency, and user trust. Key Features 1. Assets Distribution & Smart Contracts * Develop and deploy smart contracts across multiple blockchain networks (Ethereum, Polygon, Binance Smart Chain, Solana, Layer-2s). * Tokenized parcel tracking (every order minted as a digital parcel NFT). * Smart contract–based escrow for secure delivery and payments. 2. Crypto Dapps Integration * Customers and merchants interact through **Web3-enabled DApps. * Merchants can list products, track parcels, and manage disputes. * Customers can order, pay, stake, and unlock rewards. 3. IoT Hardware & Lockers * Integration with physical smart lockers for last-mile delivery. * IoT devices authenticate using off-chain secret sharing PINs. * Customers retrieve packages via multi-factor authentication (app + PIN + biometric) 4. Payment Methods (Multi-Asset Support) * Stablecoins (USDC, USDT, DAI, BUSD) for volatility-free transactions. * Native crypto tokens (ETH, MATIC, BNB, SOL) for advanced users. * Fiat on/off-ramps through payment gateways. * Optional cross-chain swaps at checkout. 5. Loyalty Rewards & Staking * Staking mechanism: customers lock DFM tokens to gain cashback & discounts. * Frequent buyers earn tiered loyalty rewards (e.g., bronze/silver/gold). * Referral bonuses for merchants and customers. 6. Dispute Resolution *DAO-based voting: disputes between merchants & customers resolved by token-holder votes. * Arbitration option: neutral third-party arbitrators selected by DAO. * Escrow release triggered only after resolution. 7. Parcel & Order Workflow * Customers submit orders via DFM Dapp. * Each parcel/order gets a unique NFT ID. * Tracking info stored on IPFS + blockchain. * IoT lockers scan & verify delivery → release goods only to authenticated customer. 8. Authentication & Off-Chain Security * PINs and authentication codes managed through off-chain secret sharing. * Multi-layer verification (merchant → courier → locker → customer). * Ensures security without exposing private keys.
