Stripe and Paradigm’s joint blockchain project Tempo has launched its first public testnet, marking a major step forward in launching the official layer-1 blockchain.&nbsp;&nbsp;
According to a Tuesday <a href="https://tempo.xyz/blog/testnet" rel="noopener noreferrer nofollow" target="_blank">announcement</a> from Tempo, the open source testnet is now live with anyone being able to “run a node or sync the chain” and test out a range of features.&nbsp;&nbsp;
“Today’s testnet launch kicks off the next phase of Tempo’s development, with a focus on scale, reliability, and integration experience. Over the coming months, we’ll continue onboarding new infrastructure partners, adding new features and developer tooling, and stress-testing throughput under real payment loads,” Tempo said.&nbsp;

The announcement highlighted six key features that are currently live on the network. These include: dedicated payment lanes, stablecoin-native gas, built-in stable asset decentralized exchange, payments and transfers metadata, fast deterministic finality and modern wallet signing methods.&nbsp;
“Tempo is built to deliver instant, deterministic settlement, predictably low fees, and a stablecoin-native experience, which are qualities that most general-purpose blockchains still struggle to provide for financial applications,” Tempo said.

In an X post following the launch, Paradigm general partner and chief technology officer Georgios Konstantopoulos <a href="https://x.com/gakonst/status/1998412828223615392?s=20" rel="noopener noreferrer nofollow" target="_blank">highlighted</a> a feature that enables Tempo testnet users to create stablecoins directly from their browsers.&nbsp;
Stablecoins created on the network will be built via Tempo’s TIP-20 token standard. However, the specific liquidity and collateral requirements for when the actual blockchain launches are not explicitly listed in the testnet docs.&nbsp;

The testnet arrives four months after payments giant Stripe and crypto venture capital fund Paradigm <a href="https://cointelegraph.com/news/race-global-stablecoin-rails-stripe-fireblocks" rel="noopener noreferrer nofollow">unveiled Tempo</a>, and three months after Tempo raised $500 million at a <a href="https://cointelegraph.com/news/tempo-stripe-blockchain-5b-valuation-funding-round" rel="noopener noreferrer nofollow">$5 billion valuation</a>. The project kicked things off with heavy-hitter design partners such as OpenAI, Deutsche Bank, Standard Chartered and Shopify.
In the latest announcement, Tempo emphasized that it has since signed on a host of new design partners, including big names such as Mastercard, UBS, Kalshi and Klarna.&nbsp;
Late last month, Klarna, the EU-licensed buy-now-pay-later firm, rolled out a <a href="https://cointelegraph.com/news/klarna-klarnausd-stablecoin-stripe-tempo-blockchain" rel="noopener noreferrer nofollow">USD-pegged stablecoin</a> on Tempo, becoming the first digital bank on the network to do so.&nbsp;&nbsp;
