a lot of projects only use one or two network. i think you can probably be the first one who supports various network. it should be attractive for users who don't want to swap from one network to another. usdt/usdc is good, but adding more tokens would be better.
I don't see various coins there, he mentioned as far now they are accepting only tether and USDC and there are already some similar platforms available in the market with the same coins or even more but look at their terms user cannot withdraw or close their account before 3 months which is making the people away from the project just my opinion.
