Farmer-to-Consumer Marketplace on Blockchain

Direct produce listings with escrowed payment and provenance

3-4 weeks build

Overview

Farmers list produce with harvest date, farm location and photos, and buyers order directly with no middleman. Payment in test ETH is held in escrow and released to the farmer only when the buyer confirms delivery, with a timeout that refunds unshipped orders. Each lot carries a provenance record buyers can inspect. Search and listings are served from MongoDB; money and state live on Sepolia or local Hardhat.

What makes it stand up

  • 01Direct farmer listings with harvest and origin details
  • 02Escrowed payment released on delivery confirmation
  • 03Timeout refund when an order is never shipped
  • 04Per-lot provenance record with photos on IPFS
  • 05Farmer ratings drawn from completed orders
