Circle Internet Financial has released significant updates for developers using its Programmable Wallets, focusing on enhanced user onboarding and authentication through Social Logins and Email OTP (one-time password) Auth. These features aim to streamline the user experience by providing faster onboarding and more seamless transactions with user-controlled wallets. Additionally, a token standard 'enum' update has been implemented for API endpoints building on the Solana blockchain, changing the standard string from "FT" to "Fungible" to align with Metaplex standards. This change affects certain query parameters and response fields, necessitating developers to review their projects for compatibility. Circle Technology Services, LLC, which offers these services, emphasizes that it is not a regulated financial services company and advises developers to consult the Circle Developer terms of service for more information.
