Crypto and blockchain-focused financial firm Parfin has announced the creation of a new platform called Rayls, designed to enhance the privacy of the Brazilian central bank digital currency (CBDC) drex. The solution is capable of operating in a permissioned manner, where every account interacting with the system needs to go through a KYC process. This platform also includes the Rayls public chain, which can be used as Ethereum L2 to interact with other open cryptocurrency projects. Parfin pointed out that this duality may ease the integration of regulated entities such as banks and other institutions in the traditional financial world with the DeFi space.
