The project also introduced an open protocol for machine transactions (MPP), developed in collaboration with the fintech giant.<\/p>\n<p>The new blockchain is designed to handle a large volume of operations. Alongside the release, the team unveiled a catalog of over 100 services that have already integrated Tempo&#8217;s solutions. These include Alchemy, Dune Analytics, and Merit Systems.<\/p>\n<h2 class=\"wp-block-heading\">Funding and Partners<\/h2>\n<p>In October 2025, Tempo <a href=\"https:\/\/forklog.com\/en\/news\/tempo-valued-at-5-billion-following-500-million-funding-round\">raised<\/a> $500 million in a Series A round, valuing the company at $5 billion. Investors included Thrive Capital, Greenoaks, Sequoia Capital, Ribbit Capital, and SV Angel. Initially incubated by Stripe and Paradigm, they did not participate in the latest round.<\/p>\n<p>The public testnet <a href=\"https:\/\/tempo.xyz\/blog\/testnet\">operated<\/a> since December. During this period, major players from commerce and finance sectors joined the ecosystem, including Anthropic, DoorDash, Mastercard, Nubank, OpenAI, Revolut, Shopify, and Visa.<\/p>\n<p>Companies are testing the use of <a href=\"https:\/\/forklog.com\/en\/news\/what-are-stablecoins\">stablecoins<\/a> for cross-border transfers, global payments, and <a href=\"https:\/\/forklog.com\/en\/news\/what-are-rwas-real-world-assets\">tokenized<\/a> deposits.<\/p>\n<h2 class=\"wp-block-heading\">Machine Payment Protocol<\/h2>\n<p>A key feature of the launch is the implementation of the MPP standard. It allows software agents and services to conduct payments automatically. The protocol&#8217;s code is open source.<\/p>\n<p>MPP operates not only on the Tempo blockchain. The standard is compatible with various financial gateways:<\/p>\n<ul class=\"wp-block-list\">\n<li><strong>Visa<\/strong> adapted it for card payments;<\/li>\n<li><strong>Stripe<\/strong> \u2014 for wallets and its platform;<\/li>\n<li><strong>Lightspark<\/strong> \u2014 for Bitcoin payments via the <a href=\"https:\/\/forklog.com\/en\/news\/lightning-network-faster-cheaper-bitcoin-transactions\">Lightning Network<\/a>.<\/li>\n<\/ul>\n<p>The protocol supports a &#8220;session&#8221; function for continuous payments. An AI agent reserves funds in advance and spends them as services are consumed. This eliminates the need to confirm each on-chain operation \u2014 the system simply aggregates thousands of microtransactions into one final transfer.<\/p>\n<p>Back in February, Stripe <a href=\"https:\/\/forklog.com\/en\/news\/stripe-unveils-payments-for-ai-agents-using-usdc-and-x402-protocol\">announced<\/a> a preliminary version of a tool for autonomous machine transactions.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Tempo platform has activated the mainnet of its L1 blockchain.
