Payments blockchain Tempo launches public testnet

Tempo, a payments-focused blockchain backed by Stripe and Paradigm, has launched its public testnet, CoinDesk reported. Kalshi, UBS, Klarna, and Mastercard have joined as network partners, alongside existing partners such as Deutsche Bank, Visa, Shopify, OpenAI, and Nubank. The network charges a fee of around 0.1 cents per transaction, which is settled using a dollar stablecoin, eliminating the need for a separate gas token.
