Payment Methods

Supported payment rails and virtual accounts including SEPA, ACH, FedNow, Wire, and SWIFT. Several banking partners in the background provide redundancy and fallback.

Iron routes fiat payments across several banking partners behind one API. If a banking partner cannot process a payment for a specific customer or industry, Iron falls back to another. Redundancy is built in, so you never integrate a second banking provider.
