Non-fungible tokens, or NFTs, have transitioned from experimental projects to serious financial instruments over the past few years. Each NFT represents a unique ownership identifier for a digital asset recorded on the blockchain and protected against counterfeiting. From the moment they appeared, NFTs have revolutionized the way digital ownership is perceived, enabling creators and collectors to buy, sell, and trade digital items with confidence. This technology ensures authenticity and scarcity, making digital assets as valuable as physical collectibles. As the market grows, NFTs are increasingly used in various industries, including art, gaming, and entertainment, opening new opportunities for monetization and digital asset management.
