Which partners joined Tempo testnet?

TLDR

Tempos testnet launch brought in four new partners: Klarna, Kalshi, Mastercard, and UBS, confirmed in a CoinDesk report.

1. They join earlier partners including Deutsche Bank, Visa, Shopify, OpenAI, and Nubank per coverage.
2. The testnet focuses on stablecoin-native payments with low fees and instant settlement, as noted by a launch article.
3. Goal: real-world payment trials on-chain by banks, card networks, and fintechs.

Deep Dive

1. New Partners

The new additions with Tempos public testnet are Klarna, Kalshi, Mastercard, and UBS. Multiple outlets list the same set of names at launch, for example a CoinDesk report.

• These firms span consumer finance (Klarna), prediction markets (Kalshi), global card networks (Mastercard), and banking (UBS). This mix suggests Tempo wants broad coverage from checkout to clearing and treasury.
• A separate summary also confirms these four joined at testnet debut, aligning with early institutional outreach by Tempos backers ([CoinDesk coverage above]).

2. Existing Design Partners

The newcomers sit alongside earlier design partners such as Deutsche Bank, Visa, Shopify, OpenAI, and Nubank, per independent coverage.

• This cohort covers banks, global payments, ecommerce platforms, and AI firms. It positions Tempo to test varied flows, from cross-border payments to AI-driven commerce.
• The breadth of participants increases the odds that testnet experiments mirror diverse, real-world payment conditions.

3. What They Are Testing

Tempos testnet emphasizes payments-specific features: stablecoin-native gas, dedicated payment lanes, fast deterministic finality, and browser-based stablecoin creation on the TIP-20 standard, as noted in a launch article.

1. Stablecoin-native gas removes exposure to volatile native tokens for fees, improving cost predictability for enterprises.
2. Dedicated payment lanes aim to preserve low fees and throughput even during traffic spikes.
3. Instant finality targets checkout reliability and reduces settlement risk for institutions.

Conclusion

The answer is Klarna, Kalshi, Mastercard, and UBS. They join a pre-existing roster that includes Deutsche Bank, Visa, Shopify, OpenAI, and Nubank. If these trials translate to production pilots, Tempos payments-first design could find a fit in stablecoin settlement where cost, speed, and certainty are decisive.
