Overall everything looks great!

Though it looks to me the logic to determine if we should block lightning needs to compare currently connected peers vs blocktank trusted peers (see comment)

Thanks for updating the logic in CoreService 👍🏻

I tried testing this for the basic and easiest test: using USA IP address with VPN.

Test Scenario: Geoblock USA

1. Uninstall app
2. Connect via VPN to USA IP
3. Open app > create new wallet
4. Go to Receive > tap Receive on Spending Balance
5. 🔴 expected: see geoblock UI
   actual: I see amount UI

I looked at the implementation and it seems it currently applies only when the user already has a LN channel, which is not necessarily the CJIT flow.

I dug a bit in the code and noticed that we don't currently check the explicit CJIT case:

Thanks! I forgot this flow

Sorry again, fixed the navigation

Great end result 🚀 , thanks a lot for addressing all comments and shaping it up to this state 🙌🏻

Gave testing one more spin:

1. 🟢 CJIT (New wallet on USA IP) - geoblock UI shown
2. 🟢 Existing wallet with LN (on USA IP) - geoblock UI shown

Ready to merge 🎉
