MetaCropX: A Blockchain-based Architecture for Dynamic Tokenization and Smart Crop Lifecycle Management

Abstract

This paper proposes MetaCropX, a smart agriculture framework that introduces a dual-token design to represent and track field-level events as they occur. Upon detecting a real-time crop event, a fungible AgriTrack Token (ATT) is minted and incrementally updated using stack-based metadata appends, maintaining an immutable record of disease status, treatments, and environmental conditions. Role-Based Access Control (RBAC) enforced via smart contracts ensures that only authorized stakeholders contribute metadata. At the end of the crop cycle, selected ATTs are converted into a single non-fungible AgriProof Asset (APA) token consisting of the verified crop lifecycle. On the other hand, off-chain InterPlanetary File System (IPFS) storage reduces on-chain data load and supports efficient metadata management. Simulated crop scenarios validate transitions, role enforcement, and metadata integrity. The proposed framework enhances transparency and traceability by allowing the stakeholders to verify the crop data in a secure manner.
