How MoonPay Powers 24/7 Stablecoin Settlement with Fiat Republic

About MoonPay

MoonPay is one of the world's leading crypto payments companies, operating as a non-custodial fiat-to-crypto gateway across more than 180 countries and 30+ fiat currencies. Founded in 2019, it has grown into critical financial infrastructure for the digital asset economy. It is often described as "the PayPal of crypto", bridging the traditional banking system and blockchain networks for both retail users and enterprise partners.

The company serves over 30 million accounts and provides the underlying rails that let wallets, exchanges, and applications offer seamless crypto purchases and sales. MoonPay has built a robust regulatory footprint to match its scale, including MiCA authorisation in the EU and New York BitLicense, giving it direct U.S. coverage in all 50 states. More recently, it has expanded into enterprise stablecoin issuance and institutional tokenised-asset infrastructure, cementing its position at the centre of the convergence between traditional finance and crypto.

Naturally, that scale and 24/7 operating model place exceptional demands on fiat infrastructure, which is exactly where Fiat Republic comes in.

Fiat Republic forms part of MoonPay's broader banking and payments infrastructure strategy, which includes multiple banking partners and direct integrations across different markets and use cases.

Especially for their Virtual Account offering in EUR and GBP, MoonPay was looking for a multi-bank API vendor that enables access to a selection of crypto-friendly banking partners in a single integration.

Highlights

• Single API, multiple banking partners. For its Iron Virtual Accounts offering, MoonPay can connect to multiple crypto-friendly EUR and GBP banking rails via a single Fiat Republic integration.
• Instant settlement that matches a 24/7 business. SEPA Instant and Faster Payments (FPS) support credits that settle in seconds, independent of banking hours, which is essential for round-the-clock stablecoin flows where customers expect immediate value.
• Improved capital efficiency. Faster, more reliable rails mean less capital tied up in settlement buffers, freeing working capital and improving the speed at which MoonPay’s virtual account service can cycle funds.
• Rail redundancy and stability. A multi-vendor banking model behind a single integration gives MoonPay operational flexibility and resilience without multiplying integration overhead.
• A team that understands crypto. Knowledgeable, responsive, round-the-clock support that streamlined onboarding and accelerated technical integration, a marked contrast to other vendors MoonPay evaluated.

The Challenge: Fiat infrastructure built for a 24/7 world

For a business operating at MoonPay's scale and speed, fiat settlement is not a back-office concern; it is core to operations and capital efficiency. The challenge? The crypto markets never close, but traditional banking does.

"Instant and reliable fiat settlement on SEPA and FPS rails is key to our business. We deal with 24/7 stablecoin settlement flows where customers expect credits independent of banking hours that settle in seconds."

For their virtual account offering under their “Iron” brand, MoonPay did a deep vendor due diligence and explored a variety of partners. Many providers were slow to respond and lacked a genuine understanding of the crypto sector and the operational realities of serving it.

"Many vendors we evaluated were slow to respond and did not understand our business needs and sector focus — crypto — well."

The Solution: One API, multiple banking partners

Fiat Republic provides MoonPay with fast, reliable EUR and GBP Virtual Account infrastructure, delivered through a single API that integrates with multiple crypto-friendly banking partners. This simplifies integration and enables MoonPay to interface flexibly with multiple banking vendors without having to build and maintain each one separately. As part of a broader multi-bank strategy, this gives MoonPay additional flexibility to route customers and operational flows across different providers while maintaining a consistent product and compliance experience.

"Fiat Republic's single API greatly simplifies our integration, as we can flexibly interface with multiple banking vendors in a single integration. While we also maintain several other direct banking integrations, we do like the flexibility of a multibanking vendor option behind a unified API and compliance infrastructure."

That per-customer flexibility, combined with a unified compliance layer, gives MoonPay both the redundancy of multiple rails and the simplicity of a single technical relationship.

The Impact: Faster rails, better capital efficiency

The clearest operational benefit shows up in how MoonPay’s Virtual Accounts unit manages capital. The faster and more reliable the rails, the less money has to sit idle in settlement buffers, which directly improves cycle efficiency.

"The faster and more reliable the rails, the less capital has to be kept in buffers, improving cycle efficiency. With instant payment schemes like SEPA, the bottleneck becomes the banking vendor, and partnering with Fiat Republic gives us a lot of flexibility in managing our operational flows."

The Partnership: Hands-on support, at all hours

Beyond the technology, MoonPay points to the Fiat Republic team as a defining difference, particularly its responsiveness and sector expertise, which smoothed onboarding and sped up integration.

"Fiat Republic's team is knowledgeable and responsive, providing hands-on support that streamlined onboarding and accelerated the technical integration. We value instant communication at all hours, and Fiat Republic has been excellent in this regard."
