MSB Registration requirements for apps regarding cryptocurrency

I submitted my Solana memecoin trading app to the App Store and I was returned with they reply "- If you intend to distribute the app in the United States, provide a copy of your Money Services Business (MSB) registration. Additionally, confirm that you will restrict the app's availability to the states listed on your MSB registration."

When I looked into it, it seems the MSB registration would mean a money transmitter license along with it. These are insanely expensive, and I know for a fact that other crypto apps did not all go through this for every state.

I use a third party API for all transactions and keys are stored on the users devices, so I don't even understand the requirement for a transmitter license if the app never even handles money.

I have been on hold with apple phone support for 2 hours (seems it doesn't work) when I replied with the App Store Connect with my questioning they just resent the same message which frustrated me.

Can anyone offer some guidance here?
