What is OpenSea and how to use it?

The rise of nonfungible token (NFT) marketplaces has ushered in a new era, fundamentally reshaping the way we perceive and interact with digital assets. They provide a new medium for artists to showcase their creations and establish a direct and meaningful connection with their audience. OpenSea has taken center stage in this revolution.
