What legal rules apply to US merchants?
US merchants that accept crypto for goods or services have tax duties. The IRS treats digital assets as property, so the sale is usually taxable. On federal returns, including Form 1040, there is a digital asset question you must answer Yes or No. A business that transmits customer funds may also have anti-money-laundering duties.
How is it not an exchange or wallet?
An exchange and a consumer wallet serve the customer, not the merchant's checkout. A wallet can send a payment, but it does not create invoices or settle a sale. An exchange can convert coins, but it does not mark an order paid. A payment gateway is built for sales: it creates an order, watches for payment, and reports the result. Some exchanges and wallets offer merchant payment services, so the line can blur.
