In-App Crypto Payment

Overview

An in-app crypto payment is a cryptocurrency or stablecoin payment initiated from within an application for digital goods, physical products, subscriptions, account funding, or services. The app can connect an external wallet, use an embedded wallet, or call a custodial account API.

The payment must show the exact asset, network, amount, recipient, and contract action before authorization. In-App Crypto Payment records should preserve pricing, authorization, transaction evidence, confirmations, fees, settlement, and any exception or refund as separate states. The application should create a unique payment request and should not trust the client to calculate final totals or report settlement. Related operational concepts include crypto payment and Mobile Crypto Payment. They should remain connected through identifiers and evidence without being treated as the same payment state, control, or financial result.
