Hello. This is Klaytn API Service team.
Please refer to the following information about updating the Global Fee Payer.
In order to change the fee payment method for KIP-17 contract to Global Fee Payer, you need to set the enableGlobalFeePayer option as ‘’true.”
Reversely, change the same enableGlobalFeePayer option as ‘’false” for the case of KIP-7 contract.
