TechFlow News: On March 18, according to official announcements, Tempo—the blockchain project jointly developed by payments giant Stripe and crypto venture capital firm Paradigm—has officially launched its mainnet. Developers can now build on it via public RPC endpoints.
Released in tandem with the mainnet is the Machine Payment Protocol (MPP), an open standard co-drafted by Stripe and Tempo. MPP provides a unified coordination mechanism for programmatic payments between agents, supports multiple payment methods—including stablecoins and bank cards—and is compatible with various payment rails. Visa has extended MPP to card-based payments across its network, while Lightspark has extended it to Bitcoin Lightning Network payments.
Additionally, Tempo states it is collaborating with partners including Anthropic, DoorDash, Mastercard, Nubank, OpenAI, Ramp, Revolut, Shopify, Standard Chartered, and Visa to drive real-world mainnet adoption.
