congrats @steve-walschot great work (and also @cass for the beautiful design) and thanks for the mention :) I'm going to see how I can implement this in future projects!

a few quick tips since it's now out in the open:

• in the payment page's .js : uncomment console.log, it's unfortunately not a web standard: https://developer.mozilla.org/en-US/docs/Web/API/Console/log I think you forgot one :)
• Maybe a <title/> on the payment page
• Maybe an instruction for people on how to make the payment on Steemit.com could be nice, hidden under an '?'
• And/or store their 'username' in a cookie so you can auto-generate the 'transfers' page for future visits: https://steemit.com/@USERNAME/transfers

Looking forward to the github / open sourcing!

thx dude keep up the good work... Let the payments begin!
