Microtransaction

A microtransaction is a small-value payment, typically for a digital good or service such as in-app features, game items, or pay-per-use content. These payments are designed to be quick and low-friction, enabling frequent purchases of low-cost items.

Because fees can be large relative to tiny amounts, platforms often rely on payment processors, stored credentials, or digital wallets to reduce friction. In crypto contexts, microtransactions may be denominated in satoshis.
