Powered by Stripe, Tempo Partners Mastercard & UBS to Launch Public Testnet!

Jakarta, Pintu News – Tempo, a payments-focused blockchain backed by Stripe along with Paradigm, has just launched its public testnet. The collaboration involves some big names such as Mastercard, Klarna, UBS, and Kalshi, with the aim to facilitate stable and efficient stablecoin payments. This initiative marks an important step in the integration of blockchain technology into the mainstream financial system.

Strategic Cooperation and Partner Expansion

Tempo, which was first introduced in September, is specifically designed for large-scale financial transactions. With the launch of this testnet, various fintech companies, banks, and developers are given the opportunity to test the network’s performance before the actual production launch.

The partnership with Stripe has brought a number of new players into the fold, including Klarna and UBS. They join early design partners like Deutsche Bank and Visa, creating a collaboration between traditional banking, global card networks and digital finance platforms.

Overcoming Blockchain Adoption Barriers

One of the main challenges in blockchain adoption for everyday payments is the volatile transaction fees and reliance on gas tokens. Tempo offers a solution with very low transaction fees, around ten cents per transaction, paid with stablecoins denominated in US dollars.

The network also offers instant finality, which is critical for real-time transactions such as cashier payments, remittances, and time-sensitive financial transactions. Testnet will be the arena to test these technical claims, allowing participants to assess throughput, reliability, and integration complexity under real conditions.

The Future of Stablecoins and Payment Infrastructure

Stablecoins are moving from a crypto trading tool to a broader financial infrastructure. With assets estimated at $300 billion, the use of stablecoins for cross-border payments and treasury operations is increasing.

A recent report from Keyrock and Bitso projects that business-to-business payments, peer-to-peer transfers, and card-based transactions will be the main drivers of stablecoin growth. This indicates an increased demand for programmable and dollar-denominated settlements, along with the digitization of global payments.

Conclusion

With support from Stripe and Paradigm and a global network of partners, Tempo enters this phase with strong institutional backing. The launch of Tempo’s public testnet comes at an opportune time as stablecoins begin to make inroads into mainstream commerce and the competition to define the dominant infrastructure for on-chain payments intensifies.
