This newsletter is made possible thanks to 1inch Network!
The popular DeFi platform 1inch has expanded to the 1inch Network by creating multiple protocols, products and teams, all based around the idea of providing instruments for users to maximize their financial opportunities in DeFi.
Currently, the 1inch Network consists of five independent yet interoperable components. In addition to the 1inch Aggregation Protocol and 1inch Liquidity Protocol, which are already admired in the DeFi space, the other three components are the 1inch DAO, 1inch Labs and the 1inch Foundation. For more info check the 1inch.io and follow the 1inch Network’s official Twitter!
