Tempo Blockchain Launches Testnet with Stripe Backing, Adds Mastercard, UBS, and Kalshi as Key Partners

The Tempo blockchain, a project backed by payments giant Stripe, has officially launched its testnet phase. This critical development milestone marks a significant step towards its mainnet release. In a major boost for adoption, Tempo has announced the addition of several high-profile partners, including financial services leader Mastercard, global investment bank UBS, and prediction market platform Kalshi. These partnerships aim to explore and integrate real-world asset (RWA) tokenization and blockchain-based financial applications. The testnet will allow developers and the new enterprise partners to test Tempo's infrastructure, which is designed for high-speed, low-cost transactions targeting the traditional finance (TradFi) sector. This move signals growing institutional interest in leveraging blockchain technology for mainstream financial services.
