We're using farcaster's open social graph and @openranknetwork to run a 7 day token distribution. Link has the simple steps to participate. You need to use either the farcaster wallet, @baseapp, or @zapper_fi to buy $regent and then cast about it. https://t.co/5wt2tUQL5E

a lot of questions about the @cura contest for @regent – which is normal because it is new. Not too late to get on the day 1 leaderboard, and it runs 7 days. Here's the simplest way to be eligible:...
