code lgtm
but i'm concerned that I see this part of code used in various places (CreateCollection, AvailableActions, Teleport, Transfer etc..)

get balance(): string {
  return this.$store.getters.getAuthBalance
}

shouldn't we change it too?

Fix is OK

but i'm concerned that I see this part of code used in various places (CreateCollection, AvailableActions, Teleport, Transfer etc..)

But this part of code is used for KSM on RMRK :), changing that on various places will break the app
