Crypto-fiat debit card integration
Connecting traditional and decentralized finance through a concrete payment product
The service
Designing and steering the integration of a product at the interface between traditional and decentralized finance.
- Defining the technical requirements of the bridge between the two systems
- Coordinating with the external partners involved
- Steering implementation through to production
The transferable principle
Projects that connect two distinct systems depend less on technical difficulty than on the ability to coordinate constraints coming from stakeholders you don't fully control.
Case study
Context
I led the design, development, and integration of a crypto-fiat payment card, connecting a traditional Mastercard payment network to a decentralized, blockchain-based infrastructure, within a Web3 financial services company. The project involved several companies in developing the solution, within a legal framework that was still a gray area.
The real problem
The project involved external partners whose technical constraints weren't fully known at the outset β the integration couldn't be designed from an internal perspective alone.
The approach
Defining the technical requirements of the bridge between the two systems, adjusting the architecture as constraints were identified with partners, ongoing coordination through to implementation.
The result
A functional product connecting the two systems went into production, despite partner constraints that required several architecture adjustments along the way β a result made more notable by the coordination of several companies it involved, and by navigating a legal framework that was still a gray area.
