Package directive of IvyCurrency data class was wrong. It resides in com.ivy.legacy.domain.data.IvyCurrency but directive was com.ivy.wallet.domain.data.IvyCurrency in the data class file. I fixed it thus these changes appeared as-per correct package directive in places where it's used.

Ah, I mean we need to support showing any arbitrary crypto with up to 9 decimals precision without showing unnecessary trailing digits. The correct pattern should be:

  • "###,###." + "#".repeat(9)
