A decentralised E-commerce platform with NFT based warranty
demo- video, developed for Flipkart Grid 4.0 Hackathon

Problem Statement

Currently, the validity of the warranty is determined by some physical receipt or warranty card. This poses several issues:

• The warranty document is easily falsifiable.
• The warranty document is not necessarily standard among different sellers.
  A bad acting authorized dealer could issue warranty cards for expired products “under the table”.

Why NFT ?

• NFTs cannot be falsified.
• A user can buy a product whose warranty will be issued as a standard NFT to his wallet address. This NFT can later be claimed from the claim page of the website.
• No thirdparty Verifier / Processor

Solution

• For Issuing warranty, We can use a NFT with Product details like product_id , purchase date, for User’s wallet address.
• For this, we made a API which saves Image & json files to IPFS and call smart contract’s Mint function.
• We call our Mint function after user has purchased the product.
• For Claiming Warranty, we list all the NFT in user’s wallet which were minted with our Contract address , for example if Token symbol === “FSNFT”
• Warranty can be claimed for the listed NFT on claim page , If the warranty period has not expired. for example, difference in Purchase Date – Current Date < Warranty period
