Hello. This is Klaytn API Service team. 

Please refer to the following information about an account deactivation. 

You would continue to receive tokens while your account is deactivated. However, if you update

your account as a Multisig account and then deactivate it, you would be able to still send transactions

using external keys, but you would not be able to send transactions by making KAS API calls, which is

ultimately creating transactions. (If you would like to know more about a Multisig account, please refer

to Klaytn Docs and an account & key deletion guidelines page on Help Center). If you reactivate your

account again, you would be able to use existing tokens and the tokens you received while your

account was deactivated. Please be sure that if you delete your key after you deactivate your account,

you would not be able to restore anything.

For any additional questions, you may also select Inquiry Registration above the KAS Help Center page

where you can register your inquiry. 

Thank you.

Klaytn API Service team.
