Also, Memo can have special “associate domain name” action, and if this domain has “memo”:”%account address%” in its TXT DNS record, the UI displays domain name in profile
For example, Roger Ver puts memo:bitcoincash:qzenpwe2cdvkrvnxcnp0lj2n492xu8z8uca0syfr88 into TXT DNS record of rogerver.com domain name
If Roger has performed “associate domain name” action and put rogerver.com in opreturn, memo backend fetches dns record, verifies it, and if ok UI dispolays green mark next to name
