Tempo, the new layer 1 blockchain built by Stripe and Paradigm, has launched its public testnet. Developers can run nodes, test stablecoin functionality, and explore the network's core tools for fast, low-cost payments.
In brief
- Tempo, the new layer 1 blockchain backed by Stripe, launches its public testnet with stablecoin-focused features and instant settlement.
- Developers can operate nodes, create testnet stablecoins via TIP-20, and explore payment channels, native gas, and an integrated stable asset DEX.
- Adoption is growing with the arrival of major partners, including Mastercard, UBS and Klarna, which issued the first dollar-backed stablecoin on Tempo.
Tempo opens its public testnet with features focused on stablecoins
Tempo, the blockchain developed by Stripe and Paradigm, has released its first public testnet. The network is now open for anyone to run a node, sync the chain, and test Tempo's core payment features. According to the announcementthis launch marks the next phase of Tempo’s development. The team will now focus on scale, reliability and integration. Over the coming months, Tempo plans to onboard more infrastructure partners, expand developer tools, and test capacity under real-world payment terms.
The testnet currently includes several key features designed for financial applications. These include dedicated payment channels, native gas fees to stablecoins, an integrated decentralized exchange for stable assets, payment and transfer metadata, fast deterministic finality, and modern wallet signing methods. Tempo notes that many general-purpose blockchains still struggle to provide predictable fees and instant settlement for real-world payments.
In a post on X, Paradigm CTO Georgios Konstantopoulos highlighted a testnet feature that allows users to create stablecoins directly in their browsers. These assets use the TIP-20 token standard. Liquidity and collateral requirements for the mainnet version have not yet been released.
Major Financial Partners Join Tempo as Momentum Grows
The public testnet follows a period of intense development. Tempo was announced four months ago and raised $500 million at a valuation of $5 billion shortly after. Early design partners included OpenAI, Deutsche Bank, Standard Chartered and Shopify. Tempo has since added other major partners. The last group includes Mastercard, UBS, Kalshi and Klarna. Last month, Klarna became the first digital bank to issue a US dollar-backed stablecoin on Tempo, signaling growing interest in stablecoin payments in the financial sector.
What Tempo's public testnet means for the future of blockchain payments
Tempo positions itself as a layer 1 chain built specifically for payments. The focus is on stablecoins, predictable fees and instant finality. These qualities are becoming increasingly important as businesses experiment with blockchain-based settlement systems.
Ultimately, the public testnet will now show how Tempo works in real-world conditions. Developer feedback, stress testing, and institutional integrations will shape the road to the mainnet. With Stripe and major financial institutions backing the project, Tempo is entering the market with strong initial momentum.
