Using the Blockstream Android app and I have some Sats in the lightning wallet. But I do not see any option in the app to swap out the lightning Sats to on-chain Sats (to the same wallet of the App or some other address).
I know it can be done using Boltz as a third party service, via their website. But is that really the cheapest way to do it or is there another option inside the app that I am struggling to find?
