I've been iterating on an open source self-custodial mobile Lightning app named “Monday” using LDK Node.
My development & design process so far: https://open.substack.com/pub/matthewramsden/p/iterating-on-a-lightning-wallet-for
Discussion
Using LSPs like other mobile nodes? Ecash integration at all?
Integration with all the things hopefully.
Currently a user would just open up their own channels but LDK Node just recently merged into main support for LSPS2 https://github.com/lightningdevkit/ldk-node/pull/223 so I integrated it into the iOS app already to test
Very cool. I'm not a fan of 0.00_000_000 notation, so would be nice to see that and bitcoin/sats symbols as user customizable
Also, I think you meant to make your "Read" link at the end point to this substack post, and not your tweet?

Thanks for that feedback, I think it should be customizable too, you’re right. What way/format do you yourself prefer to see balances/symbols?
Sats is the standard. Im cool with seeing it spelled out, all lowercase the way its displayed in nostr:npub1ex7mdykw786qxvmtuls208uyxmn0hse95rfwsarvfde5yg6wy7jq6qvyt9 or nostr:npub1cashappn03s3cl2ljsdntv0v28e2um5lgx4vjctqjt23pcwzjhsqmtdg5l or nostr:npub1xnf02f60r9v0e5kty33a404dm79zr7z2eepyrk5gsq3m7pwvsz2sazlpr5
