Conventional payment gateways do not make independent underwriting decisions. They function as the technical connection layer between a merchant's checkout and the acquiring bank that actually holds and manages the merchant account. The underwriting decision about whether a merchant can access the payment gateway is made by the acquiring bank, not by the gateway itself. When an acquiring bank performs the standard merchant account review and finds a MATCH list entry, it declines to underwrite the account, which means the gateway cannot be activated for that merchant regardless of the gateway provider's own policies toward high risk merchants.
This architecture means that MATCH list merchants who apply for payment gateways from providers that claim to serve high risk merchants often still encounter the acquiring bank underwriting barrier. The gateway provider may be willing to work with high risk merchants, but if the acquiring bank behind it performs a standard MATCH list check, the application fails at the bank level before the gateway-level approval is ever relevant. 27 Blockchain's MATCH list crypto payment gateway removes the acquiring bank from the architecture entirely, which removes the MATCH list check from the approval process. The gateway connects to the blockchain network directly, and the merchant's MATCH list status is not evaluated at any point in the transaction or integration process.
