What is Chargeback?
A chargeback is the reversal of a payment by the issuing bank or payment network — a consumer protection mechanism in traditional finance that does not exist in cryptocurrency's final settlement model.
WHY IT MATTERS
Chargebacks are traditional finance's consumer protection: if a merchant doesn't deliver, you ask your bank to reverse the charge. Credit card chargebacks cost merchants billions annually and take weeks to resolve.
Crypto has no chargebacks — transactions are final. This is both a feature (merchants don't face chargeback fraud) and a limitation (buyers have no recourse if scammed). The finality is by design.
Smart contract escrow provides an alternative dispute mechanism: funds are held in a contract until both parties confirm satisfaction, or a dispute resolution process determines the outcome. This gives buyer protection without chargebacks.
