The network opened on Tuesday, allowing anyone to build applications on top of the platform. Tempo is an Ethereum Virtual Machine\u2011compatible blockchain designed specifically for handling stablecoin transactions at scale. Unlike general\u2011purpose blockchains, Tempo reserves dedicated \u00ab\u00a0payment lanes\u00a0\u00bb at the protocol level that guarantee low fees. These lanes do not compete with other blockchain activity like NFT mints or high\u2011frequency trading.<\/p><p>The network also features stablecoin\u2011native gas, meaning users pay transaction fees in dollar\u2011pegged tokens rather than volatile crypto. This makes costs predictable for businesses handling real\u2011world payments. Tempo includes a built\u2011in decentralised exchange optimised specifically for swapping between stablecoins and tokenised bank deposits. Users can even create their own stablecoins directly from their web browser using Tempo&rsquo;s TIP\u201120 token standard. For beginners, this means the network is purpose\u2011built for moving money, not speculation or complex apps.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-d3020a2 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"d3020a2\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-b2f697d\" data-id=\"b2f697d\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-e1bd974 elementor-widget elementor-widget-image\" data-id=\"e1bd974\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t<img data-recalc-dims=\"1\" height=\"450\" width=\"800\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/cdn.sanity.io\/images\/dgybcd83\/production\/e5fceaf548dedf646cad5fc64eb616806fef1403-7200x4050.png?resize=800%2C450&#038;ssl=1\" title=\"\" alt=\"Tempo blockchain - Paradigm.xyz\" loading=\"lazy\" \/>\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\">Tempo blockchain - Paradigm.xyz<\/figcaption>\n\t\t\t\t\t\t\t\t\t\t<\/figure>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-81900bd elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"81900bd\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-cb9e58b\" data-id=\"cb9e58b\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-3416b3e elementor-widget elementor-widget-heading\" data-id=\"3416b3e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Major financial partners join Tempo ecosystem<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-bf3feb0 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"bf3feb0\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-e8d378c\" data-id=\"e8d378c\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-6003f62 elementor-widget elementor-widget-text-editor\" data-id=\"6003f62\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p class=\"p1\">The testnet launch adds several heavyweight partners to Tempo&rsquo;s roster of design collaborators. Mastercard, UBS, Klarna and prediction market <a href=\"https:\/\/www.blog.bim.finance\/en\/kalshi-prediction-market-raised-1-billion\/\">Kalshi<\/a> have all joined the project. They sit alongside earlier partners including Visa, Deutsche Bank, OpenAI and Shopify. These firms are testing real payment flows on the network to shape its final design before mainnet. Klarna has already announced plans to launch its own stablecoin, KlarnaUSD, on Tempo when it goes live in 2026.<\/p><p class=\"p1\">Currently, Tempo blockchain runs on four validators operated by the core team. The project plans to expand to independent validators from partners and infrastructure providers before moving to full decentralisation. In October, Tempo raised five hundred million dollars at a five billion dollar valuation to fund development. The blockchain aims to handle over one hundred thousand transactions per second with sub\u2011second finality, matching centralised payment networks. For traditional finance, Tempo represents a bridge between legacy banking infrastructure and on\u2011chain settlement.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-2eb7994 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"2eb7994\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-81fd42e\" data-id=\"81fd42e\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-6abbb56 elementor-widget elementor-widget-text-editor\" data-id=\"6abbb56\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><strong>Sources:<\/strong><\/p><ul><li><a href=\"https:\/\/tempo.xyz\/\">Tempo blockchain &#8211; tempo.xyz<\/a><\/li><li><a href=\"https:\/\/x.com\/sytaylor\/status\/1998408170969153612\">X (Twitter) &#8211; Simon Taylor<\/a><\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"<p>Stripe&rsquo;s Tempo payments blockchain has opened its public testnet, allowing developers worldwide to build stablecoin payment applications with backing from Mastercard, UBS and other global firms.<\/p>","protected":false},"author":18,"featured_media":15525,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_mo_disable_npp":"","_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[132,158],"tags":[156],"ppma_author":[145],"class_list":["post-15510","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news","category-technology-news","tag-technology"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.6 -
