⏳Product expiration

Product expiry tracker

The DEXPIRY warranty token system could include information about the product’s expected shelf life, consumables, or expiration date, which is particularly useful for products with limited use—such as batteries, medical devices, chemicals, or food items. Each token would record the production date and automatically calculate the expiration date, and smart contracts could send notifications when the end of its useful life is approaching. By integrating with supply chain systems and user applications, manufacturers and end users could transparently track product durability, plan maintenance or replacement, and prevent the use of defective or obsolete items.
