When Western Union decided to connect digital dollars to its cash network, it did not assemble a blockchain team, negotiate five vendor contracts, and spend a year on integration. It plugged into one API. That, in miniature, is the story told by a Solana Foundation case study published July 23 on Crossmint, the wallet-and-payments platform that has quietly become the integration layer behind an unusual roster of stablecoin launches — Western Union, Tala, Wirex, Paga, Robinhood Wallet, and the social trading app fomo among them.
The case study is a vendor-friendly document, as case studies are. But strip out the enthusiasm and it documents something genuinely useful for anyone evaluating how enterprises actually ship stablecoin products in 2026: a concrete inventory of what the job requires, and evidence of what happens when that inventory collapses into a single integration.
The vendor stack nobody advertises
Solana’s pitch as a settlement layer is straightforward — the chain settles in under a second for a fraction of a cent, and Token Extensions add token-level controls such as confidential transfers and programmable compliance. The Foundation’s own case study, though, concedes that settlement was never the hard part: “Getting a product to market is the harder part.”
What a stablecoin product actually requires, per the case study’s inventory, is five or more separate vendors stitched together: embedded wallets, fiat onramps, offramps back to bank accounts, stablecoin orchestration across currencies and countries, KYC/KYB and Travel Rule compliance, gas sponsorship so users never touch SOL, and transaction monitoring. Every one of those is a separate API, a separate contract, and a separate failure point — and wiring them together demands in-house blockchain, payments, and regulatory expertise that most fintechs and virtually all non-fintech enterprises do not have.
“Enterprises come to Solana with a vision of leveraging stablecoins for faster, cheaper payment infrastructure. What they lack is a clear path to production. That’s the gap we fill,” Crossmint co-founder Rodrigo Fernández Touza says in the study.
Crossmint’s answer is to put the whole list behind one developer-facing API: embedded and treasury wallets, card and Apple/Google Pay funding, offramps, one-click token checkout, stablecoin orchestration reaching 160+ countries, and the licensing layer underneath — the platform is MiCA-authorized and PSD2-licensed with SOC 2 Type II attestation, so Crossmint itself can act as the regulated entity onboarding end users. That last detail is the structural trick: the enterprise ships a compliant product without acquiring licenses of its own, and the “months of integration” timeline compresses into what the Foundation describes as a launch measured in days.
What the deployments actually look like
The case study’s customer list is more instructive than its architecture diagram, because each deployment exercises a different slice of the stack.
Western Union is the flagship. The 175-year-old money transfer company partnered with Crossmint to support the rollout of its USDPT stablecoin on Solana, integrating Crossmint’s wallet and payment APIs with Western Union’s Digital Asset Network — the bridge that links digital dollars to cash access across more than 360,000 physical collection points. “Working with partners like Crossmint helps seamlessly connect global wallets and digital platforms to Western Union’s trusted payment infrastructure,” said Malcolm Clarke, Western Union’s VP of Digital Assets. The direction of travel here is worth noting: this is not a crypto company adding a cash-out option, it is a cash network adding a stablecoin rail.
Tala, the emerging-markets lender that has disbursed $8.5 billion in credit to 14 million underserved customers, moved its consumer wallet and treasury onto Crossmint’s rails so loan disbursements, repayments, and cashback settle into customer wallets in seconds — no bank account required. For a lender whose customers are frequently unbanked, settlement speed is not a nicety; it is the product.
Wirex shows the migration path for companies that already had crypto infrastructure. The payments platform — 7 million-plus customers across 130+ countries and more than $20 billion in transaction volume — replaced its legacy externally-owned-account wallet infrastructure with Crossmint smart wallets on Solana and uses Crossmint as the regulated conversion layer behind its on/offramp flows, eliminating both the vendor stack and the CASP license it would otherwise have to maintain.
fomo and Robinhood exercise the consumer checkout piece. fomo integrated Crossmint’s token checkout so users can buy tokens with Apple Pay in one click — no wallet setup, no bridging, no gas — and the case study credits the integration with a 7x jump in weekly active traders, over $4 billion in volume, and 68,000+ first-time crypto buyers. Robinhood has integrated the same checkout into Robinhood Wallet. Paga, which processed over $11 billion across 169 million transactions in 2025, is using Crossmint to connect African fiat rails to global stablecoin settlement.
The pattern underneath: three use cases
Across those deployments the case study identifies three repeating shapes. Embedded finance: an enterprise puts a wallet and a full financial product line inside its own app — fund by card or Apple Pay, hold stablecoins, earn yield, spend via a Visa-powered card, cash out to local fiat. Money movement: treasury wallets, conversion ramps, and payouts to 160+ countries for payroll, remittance, and B2B settlement, all on licensed rails. And the newest, agentic payments: AI agents transacting inside enterprise-defined limits, using policy-bound wallets and card APIs that enforce spending rules at the wallet layer with human oversight and audit trails on every transaction.
That third category is the speculative one, but it is not hypothetical infrastructure — the policy-bound wallet and agent checkout APIs exist today, and they answer the question every enterprise asks first about autonomous payments: what stops the agent from draining the account? In Crossmint’s model, the wallet itself does.
Why this matters beyond one vendor
Crossmint joined the Solana Developer Platform at its March 2026 launch as the wallet and payments infrastructure partner, alongside early users Mastercard, Worldpay, and Western Union. “SDP allows enterprises to build in days, rather than months,” Catherine Gu, the Solana Foundation’s Head of Product for Digital Assets, says in the case study.
The strategic read is that Solana’s enterprise story now has two distinct layers, and the Foundation is explicit about it: the chain provides settlement — fast, cheap, programmable — while partners like Crossmint provide integration. The lesson from Western Union, Wirex, fomo, and Tala, the study concludes, is that enterprise adoption requires both. For enterprises weighing a stablecoin product, the practical takeaway is that the build-versus-buy calculation has shifted: the five-vendor, multi-quarter integration project that defined 2023-era stablecoin launches is no longer the default path. For the ecosystem, the open question is concentration — a single regulated intermediary behind many launches is a convenience on the way up and a systemic dependency once it is load-bearing.
Bottom line: the Solana Foundation’s Crossmint case study is the clearest public inventory yet of what enterprise stablecoin deployment actually involves — wallets, ramps, orchestration, compliance, gas, and monitoring — and evidence from Western Union, Tala, Wirex, Paga, fomo, and Robinhood that collapsing that stack behind one regulated API is now the pattern enterprises reach for first.
