Creating and selling NFTs on OpenSea Studio involves a structured approach. Begin by setting up a digital wallet compatible with Ethereum, such as MetaMask. Next, connect your wallet to OpenSea and navigate to the "Create" section to mint your NFT. Upload your digital asset, fill in details like title and description, and set your desired royalties.

Once your NFT is minted, you can list it for sale by selecting a price or opting for an auction format. Ensure you promote your NFT through social media and relevant communities to enhance visibility and attract potential buyers, maximizing your sales potential.
