###### Abstract  
Farming is a major sector required for any nation to become self-sustainable. Quality seeds heavily influence the effectiveness of farming. Seeds cultivated by breeders pass through several entities in order to reach farmers. The existing seed supply chain is opaque and intractable, which not only hinders the growth of crops but also makes the life of a farmer misable. Blockchain has been widely employed to enable fair and secure transactions between farmers and buyers, but concerns related to transparency and traceability in the seed supply chain, counterfeit seeds, middlemen involvement, and inefficient processes in the agricultural ecosystem have not received enough attention. To address these concerns, a blockchain-based solution is proposed that brings breeders, farmers, warehouse owners, transporters, and food corporations to a single platform to enhance transparency, traceability, and trust among trust-less parties. A smart contract updates the status of seeds from a breeder from _submitted_ to _approved_. Then, a non-fungible token (NFT) corresponding to approved seeds is minted for the breeder, which records the date of cultivation and its owner (breeder). The NFT enables farmers to keep track of seeds right from the date of their cultivation and their owner, which helps them to make better decisions about picking seeds from the correct owner. Farmers directly interact with warehouses to purchase seeds, which removes the need for middlemen and improves the trust among trust-less entities. Furthermore, a tender for the transportation of seeds is auctioned on the basis of the priority location _locp_, _Score_, and _bid_amount_ of every transporter, which provides a fair chance to every transporter to restrict the monopoly of a single transporter. The proposed system achieves immutability, decentralization, and efficiency inherently from the blockchain. We implemented the proposed scheme and deployed it on the Ethereum network. Smart contracts deployed over the Ethereum network interact with React-based web pages. The analysis and results of the proposed model indicate that it is viable and secure, as well as superior to the current seed supply chain system. seeds; blockchain; breeder; smart contract; agricultural supply chain; farmers; DApp 2024 16 132 132 132 132 132 132 132 132 132 132 132 132 132 132 132 132 132 132 132 132 133 132 132 132 133 132 132 132 133 132 132 132 132 133 133 134 135 136 137 138 1  
food and nutritional security, seed corporations must urgently transform themselves in line with the industry in terms of infrastructure, technologies, approaches, and management culture [2]. Breeders procure seeds and get them validated through a government entity such as a food corporation, which validates the seeds and stores them in their warehouses, which are provided to the farmers based on their demand [3]. The food supply chain is critical in terms of its impact on a country's economy and its relevance to sustaining the essential sector of any country. In this supply chain, the exchange of goods relies on complex and paper-thin settlement processes, and these processes are not very transparent, with a high risk to breeders and farmers during the exchange of value. Since transactions are prone to fraud, middlemen step in, increasing the total costs of remittances and making it difficult for the farmer to receive the right product overall. Existing seed supply chain solutions in the agricultural sector focus on enhancing transparency between producers, i.e., farmers, and consumers, with an aim to minimize intermediaries between end-users and producers [4]. In addition, systems supporting the traceability of food products and the identification of the original sources of products [5; 6] have been suggested. Furthermore, the agricultural system financially benefits from the identification of buyers ready to pay additional charges for a specific product [7; 8].
