The ecommerce giant has a new service to enable customers to use NFTs to unlock special perks, products and real-world experiences with merchants. Last year Shopify added the ability for merchants to sell NFTs using Shopify so customers don’t have to go to another site to buy them. With this new product, Shopify is taking that a step further through what’s known as “token-gated commerce.” The NFTs can come from anywhere the merchants want.
