Working conclusion

OpenPayd is best cataloged as embedded-finance and settlement-control-plane infrastructure: one integration surface spanning accounts, virtual IBANs, multi-currency balances, payments, FX, stablecoins, linked-client hierarchies, and regulated fiat-crypto conversion. The legal/group pages are especially important because they show that the business is not simply a bank API or a crypto ramp, but a multi-entity financial infrastructure stack with explicit fiat-versus-digital-asset service boundaries.
