Would be cool if @Cake Wallet integrates a button for the Bitcoin XPUB and the possibility to change the gap limit for a Bitcoin wallet.
If you are using an relay based infrastructure like Nostr just be aware that it's some kind of a distributuon system for your valuable data.
It's highly recommended to use a VPN or better Tor for such infrastructures.
