Crypto payment processor NOWPayments recently announced that it has integrated support for Cardano, which means that their plugins for various e-commerce solutions, such as Shopify and WooCommerce, now support $ADA payments.
Here is how Jeremy Firster, a Project Manager at Cardano Foundation, announced the news on Twitter on April 21:
Greetings @Shopify, #Cardano welcomes you to the family. Thank you @NOWPayments_io for supporting the growing Cardano ecosystem. #GoingforNumeroUno#CCCI#PaymentGateways
*Cardano is a free and publicly available blockchain that is open for all to use*https://t.co/5LpER40yPg

In this tweet, Firster referred to a Reddit post by Kate Lifshits, Marketing Manager at NOWPayments.
One of the first online merchants to announce that thanks to NOWPayments they were now able to accept $ADA payments was Cardano Supreme, which sells Cardano-themed mechandize.
