OpenSea

At OpenSea, we're excited about a brand new type of digital good called a non-fungible token or NFT. NFTs have exciting new properties: they’re unique, provably scarce, tradeable, and usable across multiple applications. Just like physical goods, you can do whatever you want with them! You could throw them in the trash, gift them to a friend across the world, or go sell them on an open marketplace. But unlike physical goods, they're armed with all the programmability of digital goods.
