The QR does generate about everything, text, links, addresses etc etc. I had in the past added tags to the coins for eg "bitcoin:wallet address". Users were complaining they had to be deleting the tag each time to send transactions. So to make it easier I removed it so it would be easy to send transactions effortlessly. I plan to add text of the crypto's name in the colored border as well.
also add an adress length counter/secuity verification
I set the address length to max(42 char) with the exception of stellar(xlm) which is 56 char. Also the crypto's name and the ticker/stock symbol is displayed in the QR border. Thanks for pointing it out.
make it according to the max char a cryptocurrency curently can have, so you at least prevent wrong paste, additionally you could add a adress type scanner that says this could be an adres of platform xyz. as a form of verification.
