Stablecoin Payments: Stripe’s Tempo Blockchain Launches Public Testnet
Tempo, the new layer-1 blockchain built by Stripe and Paradigm, has launched its public testnet. Developers can run nodes, test stablecoin features and explore the network’s core tools for fast, low-cost payments.
In brief
- Tempo, the new Stripe-backed layer-1 blockchain, launches its public testnet with stablecoin-focused features and instant settlement.
- Developers can run nodes, create testnet stablecoins via TIP-20 and explore payment lanes, native gas and a built-in stable asset DEX.
- Adoption grows as major partners join, including Mastercard, UBS and Klarna, which issued the first USD-pegged stablecoin on Tempo.
Tempo opens its public testnet with stablecoin-focused features
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 announcement , this launch begins 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 tooling and stress-test throughput under real payment conditions.
The testnet currently includes several key features designed for financial applications. These include dedicated payment lanes, stablecoin native gas fees, a built-in 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 an X post, Paradigm CTO Georgios Konstantopoulos highlighted a testnet feature that lets users 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 published.
Major financial partners join Tempo as momentum grows
The public testnet follows a strong build-up period. Tempo was announced four months ago and raised 500 million dollars at a 5-billion-dollar valuation shortly after. Early design partners included OpenAI, Deutsche Bank, Standard Chartered and Shopify. Tempo has since added more major partners. The latest group includes Mastercard, UBS, Kalshi and Klarna. Last month, Klarna became the first digital bank to issue a USD-pegged stablecoin on Tempo, signaling growing interest in stablecoin payments across the financial sector.
What Tempo’s public testnet means for the future of blockchain payments
Tempo is positioning itself as a layer-1 chain built specifically for payments. The focus is on stablecoins, predictable fees and instant finality. These qualities are becoming more important as companies experiment with blockchain-based settlement systems.
Ultimately, the public testnet will now show how Tempo performs under real usage. Developer feedback, stress-tests and institutional integrations will shape the road toward mainnet. With Stripe and major financial institutions backing the project, Tempo enters the market with strong early momentum.
