NFTs “can be a storytelling mechanism because of the metadata that it can include and that can be bookmarked. You can have a rarity curve that gives you all the surface areas to tell stories and build brands. But because it’s collectible, there’s a digital asset that can also form a sense of identity, you can get a community, and you can also get utility out of it,” Brotman told CoinDesk. In August 2021, Brotman and Sack co-founded Forum3 , a Web3 loyalty startup to advise retailers.
