Overview
- Tempo, incubated by Stripe and Paradigm, launched a public testnet that lets any company run nodes and build stablecoin payment applications.
- Payments-specific features now live include dedicated lanes that reserve blockspace for transactions, stablecoin‑native gas with fees around 0.1 cent, and targets for sub‑second finality on an EVM‑compatible chain.
- New design partners—Mastercard, UBS, Klarna, and Kalshi—join earlier participants such as Visa, Deutsche Bank, Shopify, OpenAI, Nubank, Revolut, DoorDash, Standard Chartered, Anthropic, and Coupang.
- Tempo confirmed integration with Chainlink CCIP for interoperability and reported onboarding 40+ ecosystem partners across wallets, custody, compliance, analytics, and developer tooling.
- The testnet currently runs with four team‑operated validators, with plans to add independent and partner validators before moving to permissionless participation; the mainnet timeline is undecided as pilots progress, including Klarna’s planned stablecoin rollout in 2026.
