Crypto at the checkout
BlingBling wanted e-commerce merchants to accept cryptocurrency alongside traditional payment methods. That meant CoinPayments API integration for multiple cryptocurrencies, merchant ID management, email templates for transaction confirmations, and separate production, test and UAT environments for safe release management.
The gateway
The gateway is a Java/Spring Boot application. It processes crypto payments through CoinPayments, manages merchant IDs and sends HTML email notifications for transaction events. Merchants are set up through a JDL-based form builder, and custom graphics rendering draws the payment widgets.
Three environments on AWS
Production, test and UAT each run on AWS EC2, with DNS managed in Route 53, which keeps deployment cycles safe. BlingBling’s merchants take crypto payments through the CoinPayments integration.
