On March 13, 2025, crypto payments company Moonpay announced the acquisition of stablecoin infrastructure startup Iron for at least $100 million. The deal, Moonpay's second significant purchase this year following the January acquisition of Helio, signals the company's deepening commitment to enterprise-grade stablecoin payment solutions.
Deal Details and Strategic Rationale
Moonpay will integrate Iron's API-driven technology to enable businesses to accept and settle stablecoin payments with near-zero friction. Iron specializes in high-performance stablecoin settlement rails, supporting major tokens like USDC and USDT while reducing transaction costs by over 90% compared to traditional payment networks. "This acquisition fundamentally changes how companies interact with crypto payments," said Moonpay CEO Ivan Soto-Wright. "Iron's stack lets us offer a plug-and-play stablecoin gateway to global merchants without requiring them to build complex infrastructure."
Iron's 30-person team will join Moonpay, and its flagship product "Iron Pay" will be rebranded as "Moonpay Enterprise Stablecoin Gateway." Moonpay plans to launch a white-label version of the technology in Q2 2025, targeting e-commerce platforms, cross-border remittance firms, and fintech companies.
Explosive Growth of the Stablecoin Market
The acquisition comes amid a stablecoin market boom. According to CoinGecko, the total market cap of stablecoins surpassed $250 billion in February 2025, with daily on-chain transaction volumes exceeding $100 billion. Enterprise demand for stablecoin payments has surged, particularly in cross-border B2B settlements, digital goods trading, and the gig economy. However, existing payment infrastructure suffers from high latency, complex fee structures, and compliance hurdles.
Iron's architecture addresses these pain points. Its smart routing engine automatically selects the optimal settlement path based on real-time network fees and confirmation speeds, reducing transaction finality from minutes to under 5 seconds. Additionally, Iron's built-in KYC/AML module supports compliance verification across 27 jurisdictions, significantly lowering the regulatory burden for enterprise adopters.
Moonpay's Transformation Journey
Founded in 2019, Moonpay initially gained prominence as a fiat-to-crypto on-ramp, supporting over 300 digital assets. In recent years, the company has pivoted toward B2B infrastructure. The January acquisition of Helio added decentralized payment protocol capabilities, while Iron closes the stablecoin gap.
Industry observers view Moonpay as evolving from a "bank for crypto banks" into a "stablecoin-era Visa." Through acquisitions, Moonpay now covers the full stablecoin lifecycle: issuance, custody, settlement, and compliance. Its enterprise client base has surged from 1,500 at the end of 2024 to over 4,300 in March 2025, processing more than $3.5 billion in monthly transaction volume.
Competitive Landscape
Moonpay's move reflects intensifying competition in the stablecoin infrastructure space. Circle (issuer of USDC) recently acquired Element Finance to expand DeFi integration, while Coinbase's Base network now supports native USDC settlement. Traditional giants like PayPal and Visa have also launched stablecoin settlement products.
Moonpay differentiates itself by emphasizing neutrality—it is not tied to any specific blockchain or stablecoin protocol, allowing flexible adaptation across assets and chains. "Our API is designed to be stablecoin-agnostic, like Lego bricks that can combine with any compliant stablecoin," said Iron's CTO.
Integration teams have begun working together, with first production cases expected in Q2 2025. Moonpay also announced a "Stablecoin First" developer incentive program, offering free API credits and technical guidance to the first 100 enrolled enterprises. As enterprise adoption accelerates, the stablecoin payment infrastructure landscape is poised for rapid transformation.
