Unsolicited Crypto Payment

Overview

An unsolicited crypto payment is a transfer received without an active invoice, payment request, expected customer obligation, or prior agreement. It may be accidental, a donation, a test, spam, attempted manipulation, or a transfer from a person seeking later credit or refund.

It differs from a spam payment because unsolicited only describes the lack of a request; the transfer may still be legitimate. It also differs from an accidental payment, which specifically results from sender error. These categories can overlap but should not be assumed from the transaction alone. If 500 USDT arrives at a merchant’s static address with no matching order, support should not credit the first customer who claims it. Related operational concepts include Spam Crypto Payment, Accidental Crypto Payment, and Refund Address Risk Check. They should remain connected through identifiers and evidence without being treated as the same payment state, control, or financial result.

The merchant should record the transfer without automatically assigning it to revenue, an order, or a customer balance. The label should be produced by a documented risk process rather than by intuition or a single vendor score. The authoritative record for Unsolicited Crypto Payment should also show the rule version, responsible system, permitted state transition, and any downstream action such as fulfillment, settlement, refund, or manual review.

It also differs from an accidental payment, which specifically results from sender error. Resolution may require identifying the sender, confirming control of a refund address, screening risk, considering legal obligations, and deciding whether the amount should be held, returned, or treated under an unclaimed-funds policy.

Governance should connect Unsolicited Crypto Payment to the original obligation, payment instructions, observed transaction, internal state, financial posting, and any fulfillment or refund. The decisive principle remains that an unsolicited crypto payment is a transfer received without an active invoice, payment request, expected customer obligation, or prior agreement.
