Highlights: Tempo launches public testnet and opens access to stablecoin apps that target fast transfers and clear transaction costs. Tempo adds payment features that support instant settlement and stable fees. Developers will gain new tools as major partners join the network to test real stablecoin payment use. Stripe and Paradigm’s joint project Tempo has launched its public testnet and opened access to developers building stablecoin payment tools. The network now runs in open source and allows anyone to run a node or sync the chain. Tempo said the launch marks a shift toward scale, reliability, and deeper integration support. The team plans to add more features and test performance under real payment loads. Tempo is designed to provide financial applications with immediate settlement and predictability. Stripe and Paradigm have moved their blockchain project, Tempo, into public testing, marking a significant step. It is designed for stablecoin payments to appeal to firms that require predictable settlement and lower costs.

These involve payment lanes that segregate trading activity transfer. Tempo also supports stablecoin-native gas to keep payment costs clear and consistent. The network offers a built-in decentralized exchange for stable assets. It also provides deterministic finality, metadata tools, and modern signing methods for secure wallets. Tempo said most blockchains still mix trades and payments in one congested lane. That structure often delays critical transfers during volatile market events. Tempo wants to solve this issue with dedicated tracks for payment flows. The team believes this design can support payroll, vendor payments, and high-frequency billing without disruption. The network charges one-tenth of a cent per payment. Tempo Launches Public Testnet with Expanded Developer and Enterprise Support Paradigm chief technology officer Georgios Konstantopoulos said the network now allows stablecoin creation directly from a browser. Tempo facilitates this process using the TIP-20 token standard. The group has not announced final collateral rules on the mainnet. Developers can still develop early tools and experiment with token mechanics. Tempo has developed rapidly since it was first introduced four months ago. The project raised $500 million at a $5 billion valuation. It also added Mastercard, UBS, Kalshi, and Klarna to its list of design partners. These companies joined earlier partners, including OpenAI, Deutsche Bank, Standard Chartered, and Shopify. Tempo said the expanded list reflects rising interest in real-world stablecoin payments. Klarna became the first digital bank to issue a USD-pegged stablecoin on Tempo. The company launched KlarnaUSD on the testnet last month. The token will go live on the mainnet in 2026. Tempo said this rollout demonstrates the network’s support for modern payment rails. Stripe and Paradigm also activated a live trial that lets companies build stablecoin payment apps. Welcome to Tempo, @Klarna. We're excited to support Klarna with fast, cost-effective, and purpose-built blockchain infrastructure as they accelerate stablecoin adoption across their user and merchant base. pic.twitter.com/TJ6CatR4d0 — tempo (@tempo) November 25, 2025 Matt Huang, Paradigm’s co-founder, said developers face complex challenges when entering blockchain payments. He said Tempo wants to close that gap through clearer workflows and simple integration tools. Stripe raised concerns about congestion that disrupts stablecoin payroll systems. Tempo separates payment traffic to reduce delays. This structure aims to support platforms that need constant uptime. Stablecoin Activity Grows as Tempo Targets Real Payment Adoption Tempo accepts any US dollar-backed stablecoin for fees. This flexibility assists companies in dealing with transfers without rigorous conversion processes. The use of stablecoins is on the rise across the globe. Nevertheless, the majority of activity remains centered on trading instead of payments. Citigroup believes that trillions of stablecoins will be in circulation once adoption is increased. The bank also noted regulatory and security risks across the sector. Stablecoin markets still record strong exchange activity each day. Yet payment use cases have not matched that pace.
