Payment button demos
Neetbux payment button can be embedded to a Web page with a custom Web component called <neetbux>. More about it is written in the documentation.
Want to create your own payment button? Use the payment button generator.
Questions that deserve an answer can of course be emailed.
Be advised that clicking a payment button means Neetbux will attempt to pay the specified amount from your wallet. A payment will fail if you're not logged in, or your wallet doesn't have enough Bitcoin SV.
