Crypto Payment Processor

Overview

A crypto payment processor handles operational parts of accepting cryptocurrency, including transaction monitoring, payment matching, risk checks, conversion, custody, and merchant settlement. The processor can provide APIs or gateways and can operate custodially, non-custodially, or through partner exchanges and wallet infrastructure. Processor and gateway are often used interchangeably, but processing responsibility should identify who detects, controls, converts, and owes the merchant funds.

For production use, material risks include custody and insolvency exposure, inaccurate detection, wrong finality, conversion loss, settlement delay, provider concentration, and unsupported transaction recovery.

Merchants should review fund flow, wallet ownership, confirmation policy, pricing, conversion, settlement, fees, status mapping, reporting, and reserves or counterparties.
