Great contribution @eugene-babichenko! Definitely agree on the transparency aspect. I'm wondering if the event should also log the previous owner. Technically the information would be available in the previously emitted events, but I think it would be good if each event was self-contained. |

@frangio added this field to the event, check it out, please. |

There was a problem hiding this comment.
This is failing to log the previous owner because it's updated in the previous line. The event should be emitted first, and then the state variable updated.

Fixed that |

Me and my team consider this feature very useful at least for debugging purposes, but we also believe it will give more transparency for library users.
OwnershipTransferredevent is being fired each time an ownership transfer really takes place (i.e. inOwnable.transferOwnership,Claimable.claimOwnershipandDelayedClaimable. Claimable.claimOwnership).
