According to official announcements, the blockchain project Tempo, jointly developed by payment giant Stripe and cryptocurrency venture capital firm Paradigm, has officially launched its mainnet today, enabling developers to build on it via public RPC endpoints. Alongside the mainnet launch, the Machine Payment Protocol (MPP) has also been released—a set of open standards co-drafted by Stripe and Tempo to provide a unified coordination mechanism for programmatic payments between agents, supporting multiple payment methods including stablecoins and debit/credit cards, while remaining compatible with diverse payment rails. Visa has extended MPP to its card payment network, and Lightspark has applied it to Bitcoin Lightning Network payments. Additionally, Tempo is collaborating with partners including Anthropic, DoorDash, Mastercard, Nubank, OpenAI, Ramp, Revolut, Shopify, Standard Chartered, and Visa to drive real-world adoption of the mainnet.
