Catenaa, Monday, December 15, 2025-Payments-focused blockchain Tempo opened its public testnet on Tuesday, marking a major step toward wider onchain settlement.
The network unveiled core features aimed at instant settlement, low fees, and stablecoin-focused transactions.
The rollout follows months of private testing as the company works to support financial firms seeking faster and predictable payment rails.
Tempo is valued near five billion dollars after raising funds from large venture firms earlier this year. The protocol aims to handle heavy transaction loads and maintain steady performance.
It has been built as an Ethereum-compatible Layer 1 and centers on fast processing suited for stablecoins and real-world payment flows.
The company said its testnet now shows how the core system operates during periods of high activity.
Prediction market Kalshi and major financial institutions including Mastercard and UBS are among its design partners.
Tempo also said it is collaborating with firms such as OpenAI, Shopify, Visa, Anthropic, and Deutsche Bank as it prepares for broader adoption.
In October, Tempo raised five hundred million dollars in a Series A round led by Thrive Capital and Greenoaks. Sequoia Capital, Ribbit Capital, and SV Angel also joined the round.
Stripe and Paradigm, which incubated the project, did not invest in that raise.
Klarna launched a USD-backed stablecoin, KlarnaUSD, on the network last month.
The token is expected to debut on Tempo’s mainnet in 2026 as the company expands its reach into digital payments backed by regulated issuers.
