NFT platforms are online marketplaces where users can create, buy, sell, and trade non-fungible tokens (NFTs). These platforms support various digital assets, including art, music, and virtual real estate, allowing creators to monetize their work while providing collectors with unique ownership rights. Popular NFT platforms include OpenSea, Rarible, and Foundation. Each platform has its own features, such as auction systems or fixed-price sales, and may focus on specific types of NFTs. Users typically need a digital wallet to store their NFTs and cryptocurrency to make transactions.
