I'm not 100% familiar with every piece of it, but at least the part that swaps LEO on Arbitrum to Dash (and vice versa) is the fully-decentralized Maya Protocol, which is its own blockchain.
Maybe @khaleelkazi can chime in on the rest of the process I'm less familiar with.
I understand, I think LEODEX White Paper is really something important!
I will be reading and giving more info! REMEMBER that this is more important than it seems! Thanks!
