A crypto payment gateway processes transactions in a sequence that differs from traditional card-based gateways in several fundamental ways. When a customer initiates payment, the gateway generates a wallet-compatible payment request that specifies the amount, the accepted tokens, and the destination address. The customer authorizes the payment from their wallet, and the transaction is broadcast to the relevant blockchain network for validation. Confirmation times vary by network, from near-instant on certain chains to several minutes on others, and the gateway monitors the blockchain until the transaction reaches the required number of confirmations.
Once confirmed, the crypto payment gateway updates the merchant's order system and records the settlement details. 27 Blockchain builds this entire transaction flow into the merchant's checkout, so the process is seamless from the customer's perspective and fully tracked from the merchant's side. Unlike traditional gateways that rely on intermediary approvals from acquiring banks and card networks, the crypto gateway confirms transactions directly against the blockchain ledger, which eliminates the authorization delays and risk-based holds that high-risk merchants encounter in conventional processing.
