Frozen: recipient is on a sanctions list
Reader link: share
Anyone with the full link can read the note after it unlocks. Share it only with the people who should read it.

Keep this one for yourself. It has no key, so it does not let anyone read the note. After the unlock, open it with this creator wallet and press Close to get the rent back.
