is there any way that we can find all scheduled deferred transactions of one account ?
I guess there's no way to find those by account at this moment, as one transaction can be signed by multiple accounts.
thanks, so, if i bought an account, the owner can schedule a deferred transaction to change the key back. buy an account is not safe now.
Resolution of this issue requires a hard fork. Changes to the code will be tracked as #6118.
