Taurus will address a new user audience: A large number of users that are until now outside DeFi are hesitant to use wallets through Metamask (et al) because of the risks inherent to this. Offering truly self-custodial secured wallets through email removes this entrance barrier for new users and lets them start trading instantly on Uniswap. Uniswap being the #1 dex in terms of brand recognition, Taurus has no plans of integrating any other Dexes apart from Uniswap in the future.
