First time I see Monday, and the KeyChain access wrapper. Since when have you been working on this?

What do you need to get Monday release ready, and give it L1 functionality too?

Can Swift-Bitcoin provide a practical Swift L1 component?

With an all Swift codebase myself, and hopefully significantly more people on mobile devices, could join in through Swift Playgrounds.

Also, while the Monday UI images look nice too, BDK Swift Wallet has my favorite wallet UI in general, the segmented receive address display, the different switchable denominations, consistent icon style, just a joy to view.
