In short
A payment gateway is the intermediary that lets a merchant accept crypto. It issues a payment address, confirms the incoming transfer and, if asked, converts the proceeds to fiat. The merchant avoids price exposure, but takes on a fee and a new dependency on the gateway operator.
Key points
- Handles address generation through to confirming the payment
- Can convert proceeds to fiat immediately on receipt
- Removes price exposure for the merchant, but charges a fee
- Exposes the merchant to the operator's outages and rule changes
Definition
An intermediary service that enables merchants to accept crypto payments, bundling invoice generation, detection of incoming transfers, fiat conversion and payout into one flow.
Accepting crypto in-house means building address assignment per order, waiting for the required confirmations, converting prices and feeding the result into accounting. A gateway packages all of that as an API or plugin that drops into an existing checkout.
Most services offer immediate conversion of incoming crypto into fiat before paying the merchant out, which removes price exposure. Fees and conversion spread are layered on top, so the net amount received is not directly comparable to a card transaction.
Waiting times also differ by asset. Chains requiring confirmations can take minutes, during which the market moves — so which moment's rate is used matters. Pin that down in the contract before signing.
Watch out for
- · Compare total cost including conversion spread, not just the headline rate
- · There is no card-style refund mechanism for mistaken or fraudulent transfers
- · If the operator drops support for an asset, existing checkout flows stop too
