Stablecoin Payments Glossary
Checkout Integration
Checkout integration embeds a stablecoin payment option into the customer-facing process used to complete an online, in-app, or other digital purchase.
Explanation
A checkout can display the amount due, supported stablecoins and networks, payment instructions, wallet-connect options, QR codes, expiration times, and payment status. Back-end services can calculate exchange rates, monitor settlement, handle retries, and return the result to the merchant's order system. Good integration also needs to manage underpayments, overpayments, refunds, and network mismatches.
Why it matters
Checkout design affects payment completion rates, user error, transaction monitoring, and the merchant's ability to reconcile stablecoin payments with orders.
Example
An online checkout can show a USDC option, generate a payment request, and automatically update the order when the required transaction is received.
