I want to add ADA payments to my wordpress site, does someone has an idea how ?
You have two options:
https://mycryptocheckout.com/: I’ve used their plugin before on WP and it works great. However, as of now, it doesn’t support ADA. If you contact them, they might add it for you
NowPayments I don’t have much information about this one, but they say that they accept ADA.
I hope that helps.
