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.

AtomicAssets is a standard for Non Fungible Tokens (NFTs) on the eosio blockchain technology. Anyone can utilize the AtomicAsset standard to tokenize and create digital assets and buy, sell & auction assets utilizing the AtomicMarket marketplace. Collections are meant to group assets together and also handle the permissions for these assets. They also contain a data field that follows a unified schema, where you can later add things like a description or a website URL. This information then helps 3rd party websites and applications to display more relevant information about your collection. Since each asset needs to belong to a collection, you should create one using the createcol action. Make sure to include the account that you want to create your assets with in the authorized_accounts parameter, as only the accounts within this list will be able to create and edit assets.
