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.

For any additional questions, you may select Inquiry Registration above the KAS Help Center page where you can register your inquiry. 

Thank you.

Klaytn API Service team.
