Stablecoins have rapidly evolved from a niche crypto tool into a serious force in global payments. In fact, stablecoin-backed card usage has been one of the fastest-growing segments in fintech — with crypto card volume increasing 106% annually since 2023, reaching an $18 billion annualized market by late 2025.
The opportunity is clear.
But for most fintechs, actually building stablecoin-powered payment products has been anything but simple.
The Problem: Too Many Moving Parts
Launching a stablecoin-funded card product has traditionally meant stitching together multiple providers:
Each layer comes with its own integrations, contracts, and complexity. The result?
Months of development time and heavy engineering lift — often too much for many
That friction has been the biggest barrier between stablecoin innovation and real-world usability.
The Solution: One Connected Stack
Today, Wirex and Crossmint are changing that.
By integrating Crossmint’s smart wallet and stablecoin orchestration infrastructure directly with Wirex’s card issuance platform, fintechs can now access a unified stack that connects stablecoin balances directly to real-world spending.
What previously took months can now be deployed in days.
“This is what it looks like when two pieces of infrastructure are built to fit together,” said Daniel Rowlands, General Manager, Onchain Finance at Wirex. “Fintechs can now give their users a Wirex debit card funded directly from a Crossmint wallet, and as they grow, the full BaaS stack is there when they need it.”
Turning Stablecoins into Spendable Money
The integration builds on an existing partnership — Wirex already uses Crossmint’s infrastructure to power its next-generation wallet architecture.
Now, that same capability is available to any fintech building on Crossmint.
“The gap between holding stablecoins and spending them has always been an integration problem,” said Rodri Fernández Touza, Co-Founder of Crossmint. “This closes it. Fintechs get one stack — and their users get a Wirex debit card funded directly from their Crossmint wallet.”
In other words: stablecoins are no longer just something you hold. They become something you spend.
How It Works
The integration splits responsibilities cleanly across both platforms:
Crossmint powers the crypto layer:
-
Smart wallet creation and management
-
Blockchain abstraction (no deep crypto expertise required)
-
Cross-chain stablecoin orchestration
-
On-chain transaction processing
Wirex powers the financial layer:
The result is seamless.
A fintech using Crossmint can now offer:
-
Wirex-powered debit cards
-
Funding directly from stablecoin wallets
-
Acceptance at 80+ million merchants worldwide
-
Apple Pay and Google Pay compatibility
And importantly — all of this is live today.
More Than Just Cards
While card issuance is the starting point, it’s not the end goal.
The combined Wirex + Crossmint stack is designed to evolve alongside the fintechs building on it — expanding from cards into a broader neobank experience over time.
Looking ahead, this infrastructure also lays the groundwork for something even bigger: agentic finance.
As AI agents begin to participate in financial systems, they will need the ability to:
Stablecoins — paired with programmable wallets and real-world payment rails — are a natural fit.
This integration positions both companies at the center of that future.
Building the Next Generation of Payments
For fintech builders, the message is simple:
You no longer need to assemble the stack yourself.
You can go from wallet to card to global spending — all within a single, integrated system.
