• OpenSea — Buy and sell NFTs

• From the CoinDesk 50:

"Founded by former Pinterest engineer Devin Finzer, OpenSea has developed into the Etsy of crypto. The idea of scarcity of digital items was once unthought of, but now the largest general marketplace for crypto collectibles features more than 300 categories and over 10 million such items. Anything from CryptoKitties to artworks and game pieces can be trustlessly bought and sold by users from around the world. Having dominated the non-fungible token market, OpenSea is seeing traction outside of the crypto ecosystem by expanding into asset classes like domain names, software licenses and even physical assets."
