How do I know what I'm buying is legit?
Check the contract address!
Each store is its own smart contract on the blockchain - which means it has a special address that no other store has.
Each item belongs to a store (smart contract) and shares that same address, and each item has a token ID as well that is unique to that item.
The store's address - there will only ever be one store with this address
If you are buying an item and want to make sure its legit, you can check the store's address and make sure the item you are buying belongs to that store.
