AI-powered agricultural trust platform

Every harvest carries the farmer, the story, and the proof

OpenFarm gives every physical farm and every crop a verifiable on-chain identity and harvest record. Shoppers verify by scanning a QR code — sponsored transactions and zkLogin keep Web3 invisible.

Farmer Passport — on-chain identity you can trust

Every grower gets a verifiable identity on Sui: trust score, certifications, and Green Points earned with each verified season. The Passport anchors every harvest record to a real farm.

From field to scan — how trust travels

Four steps connect the farmer who grew the crop to the shopper holding the package. Web3 runs underneath; outcomes stay human.

  1. 01

    Register a Farmer Passport

    A grower establishes on-chain identity with certifications and a trust score — the anchor for every season that follows.

  2. 02

    Log season milestones

    Planting, growth checks, and delivery events form a Season Log NFT. Photos and notes upload to Walrus as the Harvest Story.

  3. 03

    AI signs field advisories

    The AI Copilot recommends disease, weather, and irrigation actions. Each advisory is signed on chain with replay protection.

  4. 04

    Consumer scans the QR

    A shopper opens the public Trust Scan page — no wallet, no gas. They see the farmer, the timeline, and the proof behind the product.

    Escrow milestones unlock payouts as harvest evidence meets on-chain gates.
