Wirex today is increasingly an infrastructure company.
The retail business gave us years of experience operating cards, accounts, payments, scheme connectivity and compliance ourselves. The shift was to take that operating stack and make it available to other companies building financial products.
We launched the infrastructure business in November 2025. In 131 days, it became the fastest stablecoin payment infrastructure to reach $1B in annualised onchain volume. That run rate has since passed $2B.
Partners can now build with cards, accounts, payouts, settlement and other financial products through one integration, with an average signed-to-live timeline of 44 days.
That is the direction of the business now. We are building the infrastructure other companies use to bring stablecoin-powered financial products to market.
In this conversation with @samconnerone, Community Lead Developer at @circle and @arc, our Group CEO and Co-Founder @matveevp explains how Wirex moved from retail into infrastructure and what that focus looks like today.

We have crossed $1B in total onchain card spend processed through our infrastructure.
The milestone comes just 10 months after our launch, alongside:
→ 100K+ total addresses
→ 11M+ total transactions
A strong first chapter, and the pace is only picking up.

Wirex is now live on Tempo for stablecoin card programs.
Through @wirexapp, enterprises can use Tempo for near-instant stablecoin settlement, simpler reconciliation, opt-in privacy, and predictable low fees for their card programs to operate at scale.

Stablecoin cards can feel global to the user while the settlement infrastructure underneath still runs through a single base currency.
@Paymentscan’s latest research looks at how that affects cross-border card costs, why multi-currency settlement can reduce the overhead, and why relatively few stablecoin card programmes support it today.
The research also highlights where Wirex is already moving ahead, with onchain settlement in both USDC and EURC and the widest local issuance footprint of any stablecoin issuer tracked by Paymentscan.
Glad we could support the research. Thanks to @Paymentscan, @tstereth and @datadashboards for the breakdown.

Another Wirex-powered money app is getting ready for launch.
Rewards are becoming a bigger part of how neobanks create an experience people want to keep coming back to, and @PulsarMoneyApp is making that part of the experience with Pulsar Pro.
It brings richer rewards, with more ways to earn and cashback users can control.
And we’re glad to be supporting that launch, with Pulsar among the first products going live on our infrastructure and @arc as the settlement network from day one of Arc mainnet on September 16.
Pulsar Pro. That's the point.
Rewards on every action, cashback you control, and the full partner stack running underneath your money app.
Live day one of @Arc mainnet, September 16.

Stablecoin banking is moving too fast for six-month launch cycles.
Stablecoin neobanks, card programmes and embedded finance products are competing in a market where new use cases can emerge quickly and user expectations change just as fast. Getting to market sooner has become part of the product strategy.
But speed only matters if the infrastructure underneath can support it properly.
At Wirex BaaS, the average path from an idea to a live product is 44 days.
A lot still has to happen inside those 44 days:
→ Product fit and programme scope are defined
→ Compliance and onboarding requirements are aligned
→ Commercial terms are finalized and the contract is signed
→ Accounts, cards and payment infrastructure are configured
→ Integrations move through sandbox testing and iteration
→ Payment flows and settlement are tested end to end
→ Final production checks are completed before launch
The timeline is shorter, but the requirements are still there.
That is increasingly what stablecoin infrastructure needs to deliver. Companies building stablecoin banking products need to move at the pace of the market while knowing the compliance, payments and operational layers underneath are ready to move with them.

Send Cards have officially launched.
Native USDC on Base can now fund everyday Visa spending directly inside @Send.
A major step for the Send product, powered by Wirex BaaS infrastructure.

Stablecoin card spend is accelerating fast, and the infrastructure behind it is scaling with it.
Great to partner with @gizmolab_ and have them integrating Wirex BaaS across their products and client builds, bringing card issuing, BIN sponsorship, fiat spend and vIBANs into the stack.
Another route for teams to build on Wirex infrastructure. 🤝
Excited to partner with @wirexapp
We’re integrating their BaaS infrastructure across Gizmolab products and for our clients: card issuing, BIN sponsorship, fiat spend and vIBANs.
For teams building with us, we handle the technical integration with Wirex end to end and support you through implementation.
At Gizmolab, we’re focused on helping teams ship production-ready payments and neobank products.
If you are building a Neobank or exploring adding cards to your product, DM us.

When you tap a stablecoin card at a coffee shop, a lot more happens than “stablecoins get spent.”
The merchant still sees a normal card payment, and to the user, everything looks simple - tap, approval, done.
But behind that moment is an entire payments infrastructure working in the background.
At the point of payment, the transaction travels through the card network to the issuer, where the card, available funds, limits and risk controls are checked before it can be approved.
Behind the balance, stablecoin infrastructure connects the value the customer holds with the card transaction. Depending on the setup, stablecoins can also be used further down the chain for settlement with the card network.
After the tap, the transaction still needs to be cleared, settled and reconciled. And if something happens later, refunds, disputes, chargebacks and fraud investigations all need to be handled too.
And that is just one transaction.
Behind every card programme sit fraud monitoring, compliance, disputes and chargebacks, card lifecycle management, Apple Pay and Google Pay provisioning, reporting, scheme requirements and the operations needed to keep all of it working reliably.
So a card programme is ultimately all of these layers working together as one system, with the card itself only being the most visible part.
We operate that infrastructure today across 75+ clients, with hundreds more exploring integrations, and +$2B in annualised onchain card spend.
And through the same API, partners can also access EUR, USD and GBP accounts, on/off ramps, FX, yield, merchant-funded cashback, Push-to-Card payouts and travel services alongside card issuance.
For teams that want to obsess over the card experience their users see while we obsess over everything underneath it, contact us at [email protected] or visit wirexapp.com/developers

Wirex is a Visa partner, an issuer for 75+ clients, and a Crypto Card
As an issuer: @wirexapp is a Visa principal member, so no sponsor bank sits between them and Visa taking a cut. They have been doing this from London since 2014
July was $161.3M, up 29% in a month, across 1.77M payments and 52,611 active addresses. A $91 average ticket, so groceries and coffee, not batch settlements dressed up as volume
Wirex says 75+ clients signed, with hundreds more in the pipeline. The ones I track myself:
BingX, Kolo, PlasBit, uTorg, Trustee, GoMining, HEVN, Coca, Simple
As a card: Wirex One launched in June and is already at $44.3M, up 114% over the last 30 days, the fastest growth in the top ten
And that $161.3M is a floor, not a ceiling. The offchain part of their settlement is not counted here at all, and the visible part alone is the second largest issuer in the market
Were you counting Wirex?
Looking for the best Crypto Card in Europe. Test #9
In my tests I pay with different Crypto Cards under the same conditions: same shop, same minute, same amount. Then I compare which one converted dollars into euros best, where the fees are hiding, and whose cashback is actually honest. These are real purchases with real receipts, and that is where the truth shows up
These seven have all finished first or second on the rate before
The basket was EUR 11.17, seven paper receipts. This time it is only the rate, no cashback
What each card charged for EUR 11.17:
- @ether_fi : $12.92
- @Backpack : $12.93
- @wirexapp : $12.93
- @krak : $13.05
- @MetaMask : $13.05
- @avici : $13.07
- @coca_card : $13.09
The mid market rate that minute, what Google shows you for EUR to USD, made it $12.92
Three cards stayed there. The other four all take about 1%, just not in the same place
Krak, help me out here. The paper receipt says EUR 11.17. Your app says EUR 11.28, calls the purchase $12.92, then takes 13.0458 USDC, and prints Fees $0.00. Which one of those is the real number?
1.3% between the cleanest rate and the priciest one. On EUR 2,000 of spend abroad that is about EUR 26 a month
Does your card even show you the rate it used?

Private early access to Pulsar opens now.
Today Pulsar goes into the hands of its first users. A small, close group to start.
Everyone on the waitlist comes next, cohort by cohort.

WE’VE REACHED ≈$2B IN ANNUALISED CARD SPEND VOLUME! 🚀
July’s $160M+ in onchain card spend pushed our annualised run-rate to ≈$2B in just 8 months since launch.
We reached $1B in 131 days, the fastest in the industry. Roughly 110 days later, that run-rate had nearly doubled.

.@Kulipa has wound down. Roughly 120,000 cards stopped working on 29 July, most with no warning. A lot of people are asking why there was no announcement. Why founders go quiet for weeks, sometimes months, while everyone speculates.
Having watched this a few times, common reasons are:
a) The lawyers take over. The moment insolvency is a live possibility, a director's duty shifts from shareholders to creditors. Every public statement becomes potential evidence. "We're fine" can become wrongful trading. So counsel says nothing and nothing is what you get.
b) Silence is the last asset. You're hunting a buyer, a bridge, anything. The second distress goes public your valuation is zero and every acquirer just waits for the administrator. @Solflare said they tried to help find a buyer. That process only exists in the quiet.
c) Sequencing. Regulator first. Then scheme. Then employees. Then partners. Then the market. Get that order wrong in a regulated business and you've made it materially worse.
d) And often the founder genuinely doesn't know yet. From the inside it rarely feels terminal until, very suddenly, it is.
Same pattern at Railsr long quiet, then a pre-pack. TenX faded over months rather than ever really announcing. (Wirecard is a different category altogether. That was fraud. Nobody thinks that's what this is)
I've known @cateland for years. He's one of the straighter dealers in this industry and I'd bet he's handling something genuinely awful right now with more integrity than most would. Card infrastructure is brutal regulated, capital-intensive and unforgiving of one bad quarter.
The lesson isn't 'founders should communicate better.' Mostly, they can't.
The lesson is architectural. Solflare's users kept their money because the card debited directly from self-custody wallets. No balances held at the issuer. The issuer failed; the funds were untouched. It's the future of finance and exactly how we've built @wirexdevelopers from the ground up
Strategise your rails with some probability that your provider might not be here next year whether it's Bridge, Rain or Wirex
