PANews reported on March 18th that Tempo, a stablecoin backed by Stripe and Paradigm, announced its mainnet launch and introduced the Machine Payments Protocol (MPP), an open standard jointly developed with Stripe, to support machine payment scenarios using various payment methods such as stablecoins and debit cards. Tempo is designed for high-frequency, small-amount, programmable payments, emphasizing predictable low fees, high throughput, and instant settlement. MPP introduces a "sessions" mechanism, enabling continuous streaming fees within a limited amount after a single authorization, supporting the aggregation of numerous small interactions into a single settlement transaction. The initial service catalog includes over 100 model, data, and infrastructure providers, with Visa, Mastercard, OpenAI, Shopify, and Standard Chartered among the partners testing scenarios such as cross-border remittances, global distribution, embedded finance, and tokenized deposits.
