Explore the Vast Ocean of NFTs with OpenSea
Non-fungible tokens, or NFTs, are playing a major role in bringing Ethereum to the mainstream. People around the globe have been minting their own NFTs representing digital art, photography, music, collectibles, in-game items, and even tweets on blockchains like Ethereum. In recent months, there has also been the rise of so-called 鈥減rofile-picture NFTs鈥 which usually are released as a set of 10,000, and range from the original CryptoPunks, to penguins, cats, dogs, monkeys, rats, and more. In this blog, we鈥檒l explore one of the world鈥檚 leading NFT marketplaces, OpenSea.
To begin buying, minting, or selling NFTs, you first need to set up an Ethereum based wallet like聽MetaMask.
