How Stripe quietly built stablecoin rails

For most of the last decade, Stripe treated crypto as a sideshow. It even switched off Bitcoin payments in 2018. Then, in barely eighteen months, it spent well over a billion dollars assembling a full set of tools to move money as stablecoins, digital coins pegged one-to-one to a real currency like the dollar. This is the clearest sign yet that stablecoins have stopped being a crypto story and become a payments one.

What exactly did Stripe buy?

Two companies, in quick succession. On February 4, 2025, Stripe closed its purchase of Bridge, a startup that builds the plumbing for moving stablecoins between businesses, banks and currencies. At a reported $1.1 billion, it was the largest acquisition in Stripe’s history. Bridge’s job is unglamorous and important: it lets a company turn dollars into a dollar-backed coin, send it across the world in seconds, and turn it back, without touching an exchange.

Four months later, on June 11, 2025, Stripe agreed to buy Privy, a firm that builds wallets you can drop into any app, the kind of account where the user, not the platform, holds the keys to their own money. Privy already powered more than 75 million accounts across over a thousand teams. Bridge moves the money; Privy holds it. Together they cover both ends of a stablecoin payment.

What is a “stablecoin financial account”?

It is the product those acquisitions made possible. At its Sessions conference on May 7, 2025, Stripe launched Stablecoin Financial Accounts in 101 countries. In plain terms, a business can now hold a balance in dollar-backed coins inside Stripe, the same way it holds a normal currency balance, and move that money in and out by regular bank transfer or on a public ledger.

The accounts support USDC, the widely used coin from Circle, and USDB, a dollar-backed coin issued by Bridge itself. The pitch is aimed squarely at businesses in countries with volatile currencies or slow banking: a way to hold and send dollars that does not depend on a local bank’s opening hours. No cardholder, and no end user, has to know a stablecoin is involved.

And now Stripe has its own blockchain?

Effectively, yes. Tempo is a payments-focused public ledger built with the crypto investment firm Paradigm. Its public test network opened on December 9, 2025, and its mainnet, the live version handling real value, went live on March 18, 2026.

Two design choices give away its purpose. Fees are paid directly in stablecoins rather than in a separate volatile token, and they target roughly one-tenth of a cent per transaction. It also ships a Machine Payments Protocol so that software and AI agents can pay for things on their own. The firms that tested it before launch read like a payments roll call: Visa, Mastercard, Deutsche Bank, Nubank, Shopify, plus AI labs OpenAI and Anthropic. A reported $500 million funding round valued Tempo at $5 billion.

Why would a payments company do all this?

The honest answer is not “Stripe believes in crypto.” It is that stablecoins solve a specific, boring problem Stripe has always had: moving money across borders is slow, expensive, and breaks on weekends. A dollar-backed coin on a public ledger moves at 3 a.m. on a Sunday exactly as it does on a Tuesday at noon, in any country, for cents. For a company whose whole business is moving other people’s money, that is a better pipe, not a new religion.

The non-obvious part is that Stripe bought the whole stack instead of renting it. The rails (Bridge), the wallets (Privy), the accounts, and now a chain tuned for payments (Tempo). When a company that processes a large share of internet commerce decides to own every layer of stablecoin payments, it is making a bet that this becomes the default way value moves online, not a niche it plugs into.

What does it mean for the rest of us?

Mostly, you will never see it. The point of all this plumbing is that it disappears: a checkout still looks like a checkout. But the building blocks Stripe just spent a billion dollars on are not reserved for businesses. A dollar-backed coin, a wallet only you control, and a cheap always-on ledger are exactly what let a group of friends settle a shared tab directly, in seconds, across borders, with Spliz, no Stripe account required.

If the word stablecoin is new to you, our plain-language explainer covers the basics, and the card networks are wiring in the same rails.

The one-line version

Stripe did not buy crypto. It bought the pieces to move dollars instantly, anywhere, and is rebuilding its own back office on them. When the plumbing of the internet’s payments quietly switches to stablecoins, the technology has stopped being a bet.

The most telling crypto endorsement of 2026 is not a price chart. It is a payments giant rebuilding its pipes.
