Paymentwall, a San Francisco-based payments provider, has moved to expand its business into Iran, even as major banks remain reluctant to do so themselves.

Paymentwall integrated the Shetab system, Iran's interbank transfer network system, onto its platform, enabling international merchants to take online payment from Iranian account holders.

Is Paymentwall a brave (and isolated) first mover? Or the first of many fintech companies looking to access a recently-opened market.
