Overview
Iron is MoonPay's stablecoin infrastructure arm. Acquired by MoonPay in 2025, Iron provides the APIs to issue stablecoins, and move money between traditional banking rails and stablecoins — quickly, compliantly, and at scale.
You might have come across Iron in one of two ways:
As a user — if you've opened a Virtual Account through MoonPay or a partner app, Iron is the infrastructure running behind the scenes
As a business — if you're a fintech, wallet, PSP, or payments team evaluating Iron as a stablecoin payments provider
Tip: This article gives you the high-level picture. For deeper guides, see the rest of this collection or visit Iron's developer documentation at docs.iron.xyz.
What Iron offers
Iron's product suite covers the full stablecoin payments stack:
Virtual Accounts — named USD, EUR, or GBP bank accounts that auto-convert deposits into stablecoins
Onramps and offramps — convert fiat to stablecoins and back, programmatically
Swaps — swap one stablecoin for another across chains
Global Payouts — send stablecoin into bank accounts across 30+ currencies
Checkout — accept stablecoins at point of sale and settle in fiat or stablecoins
OTC — large-volume ramping services for institutional flows
Stablecoin Issuance — launch and manage your own fiat-backed stablecoin

Who Iron serves
Iron is a B2B and B2B2x platform. Its customers fall into two groups:
Partners — fintechs, wallets, PSPs, exchanges, treasuries, payroll providers, and remittance platforms that integrate Iron's APIs into their own products
Customers — end-users (retail or business) who access Iron features through a partner app (for example, opening a Virtual Account inside a wallet)
End-users don't sign up for Iron directly. You'll only see Iron's name surface when verifying your identity with MoonPay or sign the MoonPay terms.
How Iron and MoonPay work together
MoonPay is the consumer-facing crypto payments platform — buy, sell, swap, and manage crypto across 160+ countries. Iron is MoonPay's stablecoin infrastructure layer for businesses building their own payment experiences.
They share licensing, compliance, and engineering resources, but serve different audiences:
MoonPay — designed for end-users buying, selling, or swapping crypto
Iron — designed for developers and businesses building stablecoin payment experiences
When you use a feature like a Virtual Account, both companies are involved: MoonPay handles the user experience; Iron handles the underlying payment rails.
Iron's licensing and compliance
Iron operates under MoonPay's global regulatory footprint, which includes:
United States — Money Transmitter Licenses across 47 states and territories, plus a New York BitLicense from NYDFS
Europe — MiCA-licensed Crypto Asset Service Provider (CASP) by the Dutch AFM, enabling EU-wide operations
Additional registrations — FCA (UK), Central Bank of Ireland, AUSTRAC (Australia), and FINTRAC (Canada)
Note: Country and currency coverage vary by product. See Iron's country coverage documentation for the most current list.
