Wrong-Currency Crypto Payment

Overview

A wrong-currency crypto payment is a payment made with a cryptocurrency or token different from the asset requested by the invoice or checkout. The destination address may still receive the transfer, but the merchant did not authorize that asset as satisfaction of the obligation.

It differs from a wrong-network payment, where the asset may be conceptually correct but sent on another blockchain. It differs from a wrong-contract payment, where the requested token type is intended but an incorrect deployment is used. It should not substitute values using a current market rate unless the merchant’s policy explicitly supports conversion. Related operational concepts include Invoice Payment Asset, Unsupported Asset Payment, and Wrong-Contract Payment. They should remain connected through identifiers and evidence without being treated as the same payment state, control, or financial result.

In practical terms, a wrong-currency crypto payment is a payment made with a cryptocurrency or token different from the asset requested by the invoice or checkout.
