Hi,

I want to find out the multisig account from which all fees will get debited (500000+ 500000+100000 in below example) of multisig transactions.

Suppose for the below example, how to identify the main multisig account?

We’ve API to retrieve the account data from public key (account/get/from-public-key?publicKey=) and cosignatoryOf property is available in response.
But its array and can be multiple and I want it for a specific transaction like the above one.

Or simply I want the account from which all fees are deducted.

Can anyone please help?

#2

Multisig account should be here transaction.otherTrans.signer I believe

#3

Yes. I cross checked the same with some of the blocks and otherTrans.signer is the one from which amount/fee is getting deducted.

Thanks!
