What is Interchange Fee?
An interchange fee is the charge that a merchant's bank pays to the cardholder's bank for each card transaction — a major cost of traditional payments that crypto transactions can significantly reduce.
WHY IT MATTERS
Interchange fees are the hidden tax on commerce: 1.5-3.5% of every card transaction goes to banks and payment networks. This costs merchants hundreds of billions annually, raising prices for all consumers.
Crypto payments eliminate interchange: a blockchain transaction has a flat gas cost (cents on L2) regardless of payment size. A $10 payment and a $10,000 payment cost the same to process.
This fee structure makes crypto particularly attractive for: high-value transactions, international payments, and markets with thin margins where 2-3% processing fees significantly impact profitability.
