The software blueprint behind Wyrr’s $400m cross-border payments business

The technology powering international payments, though, invisible to customers, determines whether money moves quickly, securely and reliably across different countries.

For cross-border payments company Wyrr, that technology has become one of its biggest competitive advantages as the firm surpassed $400 million in processed transactions.

At the centre of that growth is a software architecture designed to solve one of the payments industry’s most difficult problems, that is, building a platform that can connect different payment providers, support multiple currencies and expand into new markets without having to rebuild the system from scratch.

Wyrr said the technology, developed under the leadership of its former head of technology, Babatunde Esanju, now supports transfers across 10 countries, multi-currency digital wallets and payments to more than 500 service providers in Canada.

The company has processed more than $400 million in transactions, demonstrating how scalable payment infrastructure has become increasingly important for fintech companies looking to operate across borders.

According to Ayo Allu, Wyrr’s founder and chief executive officer, the company’s ambition from the outset was not simply to build another remittance application but to create infrastructure that could grow alongside the business.

“The challenge was not simply to build another remittance application. We needed infrastructure that could connect different providers, support multiple currencies and allow the business to enter new markets without rebuilding the product each time. Babatunde played a central role in designing that foundation,” Allu said.

Instead of tying the platform to individual payment processors, Esanju and his engineering team designed a modular architecture that separates Wyrr’s core transaction engine from the external providers responsible for moving money and settling transactions.

This approach allows the company to introduce new payment partners without changing the core platform that records transactions, manages wallet balances and performs compliance checks. Only the integration layer needs to adapt to each provider’s technical standards, making expansion into new markets faster and less disruptive.

Esanju explained that every payment provider was treated as an independent connection while the platform maintained one consistent understanding of every transaction.

“We treated every provider as an adapter around a consistent transaction model. The core platform decided what a payment meant and where it was in its lifecycle. The integration layer handled the provider-specific differences without changing how the rest of Wyrr understood the transaction,” he said.

Industry experts say this type of modular architecture has become increasingly important as payment companies expand internationally, where every country often has different banking systems, settlement networks and regulatory requirements. A platform built around interchangeable integrations can add new services more efficiently while reducing operational risks.

To improve transaction reliability, Wyrr also implemented idempotency controls that prevent duplicate payment requests from being processed. The company introduced structured transaction histories that connect its internal payment records with references generated by external providers, making investigations and reconciliation significantly easier.

Esanju said these features were designed to ensure that every payment remains traceable, even when external payment providers experience delays or temporary outages.

“Every payment needed a clear and traceable state. When an external provider was delayed or temporarily unavailable, the platform still had to protect the customer’s balance and give the operations team enough information to establish exactly what had happened. Reliability in payments is knowing the state of the money,” he said.

The company said the software architecture has enabled Wyrr to continue increasing transaction volumes while adding new settlement routes, payment partners and commercial services without compromising operational controls.

For Allu, surpassing $400 million in processed payments reflects more than business growth. It also validates the technology decisions made during the company’s early expansion.

“Reaching more than $400 million required a platform that could support increasing activity without compromising reliability. Babatunde connected technical architecture with our commercial needs and helped us build a foundation for new partners, payment flows and markets,” he added.

The platform has also been designed to support increasingly strict regulatory requirements. Following Wyrr’s registration as a payment service provider under Canada’s retail payments framework, the company strengthened its operational risk management, transaction monitoring and audit capabilities.

Esanju said compliance requirements influenced the engineering process from the beginning because payment companies must demonstrate that their controls work in practice.

“Regulation requires a payments company to prove that its controls work, not simply say that they exist. Architecture had to support auditability, operational monitoring and clear ownership when something failed. Those requirements influenced how engineering worked with compliance and operations,” he asserted.

Beyond leading software engineering, Esanju oversaw platform architecture, technology strategy and technical decision-making across product development, compliance and operations. His role also included helping shape the company’s long-term international expansion strategy.

According to Allu, the technology leadership extended beyond writing software into ensuring that Wyrr’s infrastructure could support sustained global growth.

The company said the modular platform continues to provide the foundation for expanding across countries, payment partners and settlement networks while maintaining transaction reliability, operational control and full traceability.

As cross-border payments become more competitive, Wyrr’s experience highlights a broader trend across the fintech industry: sustainable growth increasingly depends not only on attracting customers but on building resilient software capable of handling rising transaction volumes, regulatory demands and international expansion. For companies seeking to become global payment platforms, the quality of the underlying technology is proving to be just as important as the payments themselves.
