[Stripe and Paradigm Collaborate to Develop Tempo Blockchain, Now Open for Public Testing] According to Bloomberg, the Tempo blockchain, developed in collaboration between Stripe and crypto venture capital firm Paradigm, is now open for public testing and available to all businesses, focusing on stablecoin payment scenarios. New partners include UBS, Cross River Bank, and prediction market platform Kalshi, while existing partners include Deutsche Bank, Nubank, OpenAI, and Anthropic. Tempo utilizes an independent payment channel design to achieve a fixed transaction fee rate (0.1 cents per transaction), reducing the impact of gas fee fluctuations on settlements and supporting any USD stablecoin as a means of fee payment.
