Ok it will help me disable the master key ? @KukaiWallet

Based on your question and the existing answers, it appears that you are trying to disable the master key on your Kukai wallet. Unfortunately, we cannot provide assistance with this as it is not something that can be done here. If you have a system that allows a third party to disable access to your funds, then you will need to contact the appropriate support team for assistance with this. Alternatively, you could link your Trust wallet to Kukai, and then follow the instructions to disable the master key.
