The Story

NFC Authentication

• Hold your iOS or Android device up to the back of the tongue of the right shoe. Some phones require you to download a separate application to scan NFC chips. (For iOS, we recommend NFC TagInfo by NXP.)
  Scanning the chip opens a web page on your phone’s browser that will confirm that the physical pair of sneakers is authentic. (If the authentication page doesn’t automatically open, you may need to click on the URL that appears when you scan the chip.) This page also displays information about your NFT and the physical sneakers.
• The NFC chip is also entangled with your NFT confirms ownership of the sneakers in both physical and digital states. You will need to connect the account you used to purchase the pair of sneakers to the verification website by one of the following methods:
  1. If you purchased the shoe with a credit card, press the "Sign in with email" button and verify your email address by following the steps in the pop up window.
  2. If you purchased with a crypto wallet you'll need to open this URL in a browser that can connect to an Ethereum wallet. Connecting your wallet will automatically check your public key and verify your ownership.
  3. If you want to authenticate using a desktop, scroll down on the authentication page on your phone’s browser and click on the “Share Link” button which will allow you to share the link with your desktop.
• Once the authentication URL is open in your MetaMask browser on your desktop, connect the wallet that holds your Endstate NFT. This will confirm your ownership of the physical sneakers “entangled” with your digital pair.
