What was stuck

02 · What we did
How we shipped
Developer-led narrative: time-to-launch, fraud controls, reconciliation. Use cases for virtual cards, expense, and credit framed as programs you can stand up — not slides.
03 · Takeaway
Why it mattered
In issuing, the demo is a live card number — everything before that is brochureware.
Miden attacks the integration tax that keeps African card programs stuck on legacy processors. Faster launch, less fraud friction, and APIs that product teams can actually ship against.
