PANews reported on December 9th that, according to Bloomberg, Stripe's Tempo blockchain, developed in partnership with crypto venture capital firm Paradigm, has launched its public beta, open to all businesses and focusing on stablecoin payments. New partners include UBS, Cross River Bank, and prediction market platform Kalshi, while existing partners include Deutsche Bank, Nubank, OpenAI, and Anthropic. Tempo's independent payment channel design achieves a fixed transaction fee rate (0.1 cents per transaction), reducing the impact of gas fee fluctuations on settlements, and supports any USD stablecoin as a payment method for transaction fees.
