If you're new to the crypto and NFT space, there are a few things you need to set up before you can sell non-fungible tokens.

Before you can create and sell NFTs you have to buy cryptocurrency, set up a crypto wallet like MetaMask, fund the wallet with crypto like ETH, and connect your wallet to an NFT marketplace.

Once you have each of those set up correctly, you can create your nonfungible token on OpenSea and list it for sale on the marketplace. 

To recap, you need:

  • A blockchain/cryptocurrency
  • A crypto wallet 

  • An NFT marketplace 

Are you ready to sell NFTs? Let's get started.
