Tempo

Stripe and Paradigm announced Tempo on Sept. 4, 2025, as a payments blockchain they had incubated, and Stripe CEO Patrick Collison described it as an independent company with the two firms as its initial investors. Matt Huang, a Paradigm co-founder and managing partner, leads it. At its announcement, Tempo said it would not issue its own token and would accept stablecoins as transaction fees. In October 2025 it raised a $500 million Series A at a $5 billion valuation, led by Thrive Capital and Greenoaks with Sequoia, Ribbit Capital and SV Angel participating. Its mainnet went live on March 18, 2026, alongside the Machine Payments Protocol, an open-source standard from Stripe and Tempo that lets AI agents send and receive fiat and crypto payments. Corporate validators include Stripe, Visa, Zodia Custody and MoneyGram. Businesses that build on Tempo can launch stablecoin accounts for their customers, earn yield on stablecoin balances and route stablecoins across chains.
