Cyrillic Small Letter Ha
It’s a single character domain that now costs $740 dollars to register so if you paid less than that you did well! Congrats!
I always cut and paste domains into Google, Unicode-Table, or Emojipedia to see what I am getting. Always good to paste into google for spelling checks as well.
Also, for Emoji domains you can use Emojipedia to confirm exactly what an Emoji code is supposed to be by hitting “Copy” button on the site next to each Emoji and pasting it into the Bonfida domain search. Very good advice for all emojis
because what you bought is an unicode as @Yoyodyne has explained, not the small letter x.sol. Please do not transfer funds to english letter x.sol (which belongs to others). You can DM me for a refund on this domain
