Of course there isn't much LEO staked on LeoDex (I'm actually one of them) because there's nothing to gain from that right now. I had the alternative to bridge them to Hive and use them there but honestly I didn't even try, just to get a little APR for a few weeks vs the fees. You're right expecting this will go up once USDC rewards are live. And sure, this will depend on the volumes and fees, and hopefully having staked LEO will actually motivate stakers to also use LeoDex themselves or advertise it.
Afaik it's not easy to calculate the fee like that as there are pairs that have a fee discount (or even 0 fees). There will probably be more transparency over that once the rewards go live. The tokenomics here will be a bit quirky, but nothing that can't be improved going forward depending on the results. The most important part will always be economic activity aka trading volume on LeoDex. I think that if they really launch perp trading, that can make an actual difference.
yes indeed. I haven't used the Dex really because they don't support Hive there anymore. Unfortunately there re no plans to revive the support (since it was too costly to maintain it apparently).
I feel like a general issue for Hive is that there's little interoperability with other chains. Too bad LeoDex used to have that and stopped.
HBD bridged to Base or Solana would be so cool!
