Online Crypto Payment

Overview

An online crypto payment is a cryptocurrency or stablecoin transaction used to pay through a website, application, marketplace, digital invoice, or remote service. The merchant creates digital payment instructions and verifies the resulting blockchain transaction before applying it to the order. Online availability does not remove asset, network, finality, pricing, fraud, privacy, or refund requirements. When implementing Online Crypto Payment alongside Customer Crypto Payment, the payment record should preserve pricing, authorization, transaction evidence, confirmations, fees, settlement, and any exception or refund as separate states.

Important risks include phishing pages, wrong tokens, address substitution, delayed confirmations, stale quotes, duplicate payment attempts, and weak order attribution.

Systems should preserve online session, merchant, order, quote, asset, network, address, transaction, confirmation, settlement, and customer communication.

The workflow for Online Crypto Payment commonly touches In-Store Crypto Payment and Customer Crypto Payment. Documenting those handoffs keeps duplicate events, delayed updates, and manual corrections for Online Crypto Payment traceable to the correct object.
