Any merchant can upload information about their products to the Hive blockchain without needing to ask for permission. Once these products are published on the blockchain, they can be added to social shops with a single click—simply mark them with a heart.
Additionally, if merchants wish to pay commissions for referrals, they can provide affiliate codes to partners, which are then entered in the website configurations. That's how simple it is for any shop to showcase their products on the Hive blockchain.
And if a shop accepts crypto payments - great. It all works exactly the same way.
