Hi, I’m interested:) It’s exciting to see Swiftui-navigation and swift-dependencies being used in the app. It’s the only bitcoin/lightning/nostr related SwiftUI app I found so far utilizing pointfree’s libraries. I’m a longtime subscriber of Pointfree and TCA user. Any chance TCA being adopted in nos as well? 
Also may I ask why CoreData instead of SwiftData since you’re targeting iOS 17 and above only? 
On top of that, it seems all the low level utility tools like secp256k1 and bech32 are also written in Swift, ideally Rust would be a better candidate since Rust/bitcoin ecosystem is much more mature and you can easily export them to Swift using FFI, same applies to nostr-specific tools like rust-nostr, e.g. there’s already SPM package available there.
