Stripe just launched its own blockchain. The payments company, which processes transactions for millions of businesses worldwide, debuted Tempo on March 18. It’s a Layer 1 blockchain built specifically for stablecoin transactions, paired with something called the Machine Payments Protocol, which lets AI agents execute real-time payments autonomously.
From acquisition to architecture
Stripe’s blockchain ambitions trace back to its $1.1 billion acquisition of Bridge in early 2025. Bridge provided the stablecoin orchestration tools and plumbing that Stripe needed to build a crypto-native payments layer without starting from scratch.
In May 2025, Stripe rolled out Treasury stablecoin accounts to businesses across 101 countries. Those accounts let companies manage both stablecoin and fiat transactions from a single interface.
The Machine Payments Protocol and agentic finance
The Machine Payments Protocol is designed to enable what Stripe is calling “agentic finance,” a framework where AI agents can initiate, authorize, and settle payments in real time without human intervention.
MPP supports AI-operated micropayments and real-time settlements on Tempo. The protocol is built to handle the kind of high-frequency, low-value transactions that would be economically unfeasible on most existing blockchains due to gas fees.
Stripe has lined up early partners to test the system. Visa, Nubank, Shopify, and Klarna are all exploring Tempo’s capabilities. That roster spans card networks, neobanks, e-commerce platforms, and buy-now-pay-later services.
Why stablecoins, why now
Stripe’s expansion of Treasury accounts to 101 countries directly targets demand from businesses in regions with volatile local currencies, giving companies access to stable dollar-based accounts without requiring a US banking relationship.
Stripe dropped Bitcoin payments back in 2018 because they were too slow and too volatile for commerce. Its return to the space through stablecoins has been relentlessly practical. Tempo is the fullest expression of that pragmatism yet.
What this means for investors and the broader market
Stripe remains a private company, so there’s no public stock to trade on this news.
For stablecoin issuers, particularly Circle (USDC) and Tether (USDT), Tempo could drive massive new demand for stablecoins as the default settlement currency for AI-driven commerce. The Bridge acquisition gives Stripe the orchestration tools to be chain-agnostic and issuer-agnostic.
A blockchain controlled by a single company is a blockchain that can change its rules unilaterally. Enterprise customers may eventually demand the kind of neutrality and censorship resistance that only decentralized chains can provide.
