Refund Currency

Overview

Refund currency is the fiat currency or digital asset in which returned value is denominated or delivered. It may differ from pricing or settlement currency after conversion, so the refund record must preserve original value, rate, fees, precision, network, and customer-facing amount.

The record should remain linked to the original payment and preserve eligibility, amount, reason, destination, approvals, deadlines, execution reference, fees, and settlement outcome. For Refund Currency, this point supports the definition’s focus on fiat currency or digital asset in which returned value is denominated or delivered.

Refund Currency should remain distinct from Refund, because the two records can carry different authority, timing, and financial effects.

The principal failure modes are wrong destinations, duplicate returns, missed dispute deadlines, excessive amounts, unsupported reversibility assumptions, exchange-rate differences, fees not returned, unauthorized manual action, and provisional postings treated as final.
