What Ultimate does
Iron is an API-first stablecoin payment infrastructure company, founded around 2020 and headquartered across New York City, London, and Berlin. Following its acquisition by MoonPay in Q1 2025, Iron operates as MoonPay's stablecoin infrastructure brand, delivering a comprehensive suite of modules—virtual accounts in EUR, USD, and GBP that auto-settle incoming fiat into stablecoins; programmatic on/offramps for fiat-to-stablecoin conversion; global payouts to 30+ fiat currencies; a crypto checkout widget; hosted or bring-your-own KYC; and a Stablecoin Issuance platform that allows platforms to mint proprietary fiat-backed stablecoins.
The technology is delivered through clean, sandbox-enabled APIs alongside a developer dashboard and plug-and-play UI widgets, enabling customers to go from zero to live in a day. Iron monetizes via API transaction fees and OTC services, with revenue mechanics tied to transaction volume rather than publicly disclosed per-transaction pricing or subscription tiers; pricing is gated behind a demo request. Target customers are enterprise and fintech-segment buyers, including Payment Service Providers (PSPs), FinTechs, Wallets, Exchanges, Treasuries, Remittance companies, and Payroll Providers, with operational coverage extending to 100+ customer-onboarding countries.
The company's competitive position rests on three pillars: (1) the regulatory perimeter inherited from MoonPay, including 47 US Money Transmitter Licenses, NY BitLicense, MiCA CASP, FCA registration, Central Bank of Ireland registration, AUSTRAC, and FINTRAC; (2) the breadth of the API surface, which consolidates accounts, ramps, payouts, compliance, and reconciliation into a single integration; and (3) MoonPay's $490M+ VC capital base, which funds infrastructure, licensing, and global expansion that would be prohibitive for a standalone stablecoin infrastructure startup to match.

Ultimate competitors and assessment
Company assessmentDirect peers
- Transak: Transak is a global fiat-to-crypto on/offramp infrastructure provider with developer APIs and broad coverage. It directly competes with Iron's on/offramp and KYC modules for wallets, exchanges, and fintechs.
- Bridge (Stripe): Bridge is an API-first stablecoin orchestration platform for businesses, offering accounts, on/offramps, and payouts. It is the most direct functional twin to Iron, now backed by Stripe's distribution and capital after acquisition.
- Circle: Circle is the issuer of USDC and EURC and operates developer APIs for stablecoin payments, on/offramps, and cross-border transfers. It competes head-on with Iron in stablecoin banking APIs and also has a regulatory moat.
- Alchemy Pay: Alchemy Pay provides crypto on/offramp and fiat-crypto payment gateway APIs used by merchants and platforms globally. It overlaps with Iron on ramp APIs, checkout widgets, and PSP integrations.
- BitPay: BitPay is an established crypto payment processor and on/offramp provider for merchants and businesses. It is a longer-tenured peer competing on similar rails (stablecoin acceptance, payouts, settlement).
- Zero Hash: Zero Hash provides embedded crypto and stablecoin infrastructure (on/offramp, custody, trading) via APIs to fintechs, neobanks, and brokerages. It is a close comparable in API-first stablecoin rails for enterprise and fintech clients.
- BVNK: BVNK is a stablecoin payment infrastructure provider focused on enterprise cross-border payments, payouts, and on/offramp APIs. It targets PSPs, fintechs, and remittance firms similarly to Iron.
Broad incumbents
- Coinbase Commerce: Coinbase Commerce offers merchant crypto payment acceptance and settlement, and Coinbase broader provides stablecoin and onchain payment infrastructure. It overlaps with Iron's checkout and settlement products but as part of a much broader exchange/incumbent stack.
- Fireblocks: Fireblocks provides custody, settlement, and onchain payment infrastructure used by exchanges, fintechs, and PSPs. It is comparable to Iron for treasury and settlement workflows, though broader in custody and security tooling.
- Ripple: Ripple provides cross-border payment infrastructure including stablecoin-enabled rails via Ripple Payments and RLUSD. It overlaps with Iron on global payouts, FX, and B2B remittance use cases at much larger scale.
