After listing your NFT, the next step would be to either wait for a buyer to make an offer or promote the NFT across your social media platforms and your close contacts. It is important to note that the sale of your NFT is not restricted to the specific marketplace that you use to mint the NFT. Minted NFTs are mostly transferrable, which means that you can list them on different marketplaces. It is important to keep in mind that gas fees will be required for these transfer actions.
After accepting a bid, the gas fee will be paid to conclude the transaction. Also, platforms like OpenSea and Rarible will receive 2.5 percent of the NFT sale price.
