Polygon

The world’s largest digital marketplace for crypto collectibles and non-fungible tokens (NFTs), including ERC721 and ERC1155 assets. Buy, sell, and discover exclusive digital assets like Axies, ENS names, CryptoKitties, Decentraland, and more. Building brand new economies powered by true digital ownership. OpenSea is the first and largest marketplace for user-owned digital goods, which include collectibles, gaming items, domain names, digital art, and other assets backed by a blockchain. At OpenSea, we're excited about a brand new type of digital good often referred to as a non-fungible token, or NFT. NFTs have exciting new properties: they’re unique, provably scarce, liquid, 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 assets.
