Hey James,

are we satisfied with Instantdex. As I understand it is a centralised solution.
Looks like NODE is doing it decentralized. Their new algortihm is out and working. Of course till now with small amounts of transactions.
Maybe NODE will be a good additive to supernets core, by adding instant transactions.
Maybe you already know all of it, but if not, please take a look.

disclaimer: of course I own some Node, but an irrelevant amount in comparision to my supernet tokens.
