Stripe Develops 'Tempo' Blockchain for Global Settlement
Stripe is developing a new blockchain named 'Tempo' with the goal of reinventing global financial settlement. The initiative aims to create a real-time, programmable, and interoperable infrastructure for cross-border payments. This move signals a broader trend among fintechs to treat settlement infrastructure as a key competitive advantage and a core business differentiator.
Stripe's 'Tempo' is a purpose-built Layer 1 blockchain, developed from the ground up in partnership with crypto venture firm Paradigm. Unlike forks of existing blockchains, Tempo is designed specifically for high-performance payments, particularly with stablecoins, aiming to sidestep the network congestion and high fees common on general-purpose chains. The project was developed by a small team and will operate as a standalone company led by Paradigm co-founder Matt Huang. Tempo's architecture is engineered for over 100,000 transactions per second with sub-second finality, a significant leap from Bitcoin's ~10 TPS or Ethereum's ~20 TPS. It is compatible with Ethereum's EVM, allowing developers to use familiar tools, but uniquely allows transaction fees to be paid in any supported stablecoin, not a native volatile token. This is achieved through a built-in decentralized exchange for seamless stablecoin conversion. The initiative is a direct response to the doubling of stablecoin transaction volumes to $400 billion in 2025, with B2B payments accounting for 60% of that total. Stripe is positioning Tempo to be the infrastructure for an emerging "agent economy," where AI agents conduct high-frequency, automated microtransactions on behalf of users and businesses. This strategy anticipates a future where transaction demand could exceed one million per second. A public testnet for Tempo launched in December 2025, with a mainnet deployment expected later in 2026. The project has enlisted a formidable group of "design partners" to provide technical input and test use cases, including Visa, Deutsche Bank, Standard Chartered, Shopify, OpenAI, and Revolut. Klarna has already launched a bank-issued stablecoin on Tempo's test infrastructure for cross-border settlements.
