Wirex has integrated the Tempo blockchain as a settlement layer for its enterprise stablecoin card programs, giving corporate issuers a path from product design to live card issuance on a network built for payments. The announcement went out on September 10 and makes Wirex one of the first large card platforms to route card settlement through the Stripe-backed chain.
What the integration does
Wirex operates the regulated card stack: Visa program management, KYC and travel rule compliance, settlement, reconciliation, fraud and dispute handling. Tempo supplies the on-chain layer where stablecoin value actually moves. Under the arrangement, an enterprise that wants to issue stablecoin-funded Visa cards no longer needs to assemble the chain, the issuer connectivity and the compliance plumbing separately. Wirex handles the card infrastructure, Tempo handles settlement, and a joint Stablecoin Advisory group works with clients on designing the card and settlement flow, selecting infrastructure partners, and moving from architecture to prototype and production.Tempo was incubated by Stripe, the payments company, and its advisory team already works with enterprises including DoorDash, Deel, Klarna, Felix and ARQ. Wirex said the choice came down to Tempo’s payments pedigree rather than raw chain specs: the network was designed specifically for stablecoin payments, with fees and structure built around high-volume card flows rather than trading.
Scale behind the deal
Wirex claims $1 billion in annualized on-chain volume, reached roughly 131 days after launch of its current infrastructure, which the company calls the fastest run to that figure in crypto card history. It operates as a principal member of both Visa and Mastercard and covers more than 130 countries. Settlement on its dual-stablecoin network runs in USDC and EURC, and the Tempo integration adds a dedicated chain for enterprise programs on top of that. Its card programs support physical and virtual cards, Apple Pay and Google Pay, and non-custodial models where the issuing business keeps control of user funds.Tempo’s own client list is the other half of the story. DoorDash, Deel and Klarna are mainstream consumer and payroll businesses, not crypto-native firms. Their presence suggests stablecoin card rails are being adopted by companies whose customers may never see the word blockchain, which has been the quiet thesis of the stablecoin payments sector all year.
A crowded but fast-growing market
The deal lands amid a wave of card and stablecoin infrastructure launches. On the same day, MoneyGram launched a stablecoin payment card with Stellar and Crossmint that lets users spend stablecoins anywhere Visa is accepted. Earlier this week, U.S. Bank completed a live cross-border pilot of its USBDC stablecoin on Stellar, and a 21-bank consortium including Bank of America, Citi and Goldman Sachs is building a jointly issued dollar stablecoin for 2027. Singapore’s central bank also opened a consultation this month on recognizing some foreign-issued stablecoins, a signal that regulators are racing to keep up with issuance.The stablecoin market itself has expanded from roughly $200 billion at the start of 2025 to around $303 billion, according to DeFiLlama data cited by CoinDesk. Payment volume, not trading, drives most of that growth now, and cards are the retail-facing edge of it. Wirex’s bet is that enterprises will pay for a bundled stack instead of stitching one together from a chain, a card issuer and compliance vendors.
The open questions
The announcement does not name specific enterprise clients going live on Tempo through Wirex, nor a timeline for the first programs. It also does not disclose which stablecoins will settle on Tempo for enterprise cards beyond the company’s existing USDC and EURC support. Regulation remains the structural constraint: card programs in the US and EU still carry the same KYC, sanctions and consumer protection obligations regardless of the settlement chain, which is why the regulated issuer layer, not the blockchain, is where most of the operational work sits.For Wirex, the move positions it as an aggregator at a moment when every large payments firm wants stablecoin exposure but few want to build chains themselves. For Tempo, it converts Stripe’s payments credibility into live card volume. The comparison that matters over the next two quarters is whether bundled stacks like this one win enterprise mandates faster than the do-it-yourself route, and whether card spending on stablecoins grows fast enough to justify more than one settlement chain competing for the same programs.
