I am very confused since in the Dapp marketplace course they are using the smart contract that has NFT token already linked with the marketplace. And in Rarible and Opensea allow users to create the token. The question is that mean they create a new smart contract or just add a new token to the smart contract we create in the beginning?
if the answer is the first one, how we can create a new smart contract from the frontend?
if the answer is the second one what is the symbol and name of the token?
