I have looked into Sifchain previously, despite using the keyword “Omni” they do not actually mean the Omni Protocol. They have not listed the 25 other chains they want to swap between but again, Omni Protocol is probably extremely low priority because the temporary MaidSafeCoin is the last project left on it. This also goes for Thorchain… why would devs put priority time or effort into supporting Omni Protocol just for one temporary project coin called MaidSafeCoin, that BTW has very low liquidity and number of users? It does not make much sense from a resource allocation POV. It might happen, but the probability seems stacked against it or at least very far off in the future.
That is why pursuing an ERC20 (or BEP20 if that is easier I don’t care so much which, as more the where are the Mobile wallets, users and liquidity) option right now is still the optimal path to ensure access for Everyone at launch time.
