If you are a Clan Leader and want to pass your rights to another clanmate, you need to leave the Clan:

 

1. Press the "Leave Clan" button in the clan menu

2. Choose the player who you want to appoint as your successor.

 

If you want to pass your role to another player without leaving the Clan, please contact our support team.

Please make sure you have specified which player you want to assign as a new Leader.
