SignerListSet

[Source]

The SignerListSet transaction creates, replaces, or removes a list of signers that can be used to multi-sign a transaction. This transaction type was introduced by the MultiSign amendment.

Example SignerListSet JSON

{
    "Flags": 0,
    "TransactionType": "SignerListSet",
    "Account": "rf1BiGeXwwQoi8Z2ueFYTEXSwuJYfV2Jpn",
    "Fee": "12",
    "SignerQuorum": 3,
    "SignerEntries": [
        {
            "SignerEntry": {
                "Account": "rsA2LpzuawewSBQXkiju3YQTMzW13pAAdW",
                "SignerWeight": 2
            }
        },
        {
            "SignerEntry": {
                "Account": "rUpy3eEg8rqjqfUoLeBnZkscbKbFsKXC3v",
                "SignerWeight": 1
            }
        },
        {

                "SignerWeight": 1
            }
        }
    ]
}

SignerListSet Fields

In addition to the common fields, a SignerListSet transaction uses the following fields:

Field	JSON Type	Internal Type	Description
SignerQuorum	Number	UInt32	A target number for the signer weights. A multi-signature from this list is valid only if the sum weights of the signatures provided is greater than or equal to this value. To delete a SignerList, use the value 0.
SignerEntries	Array	Array	(Omitted when deleting) Array of SignerEntry objects, indicating the addresses and weights of signers in this list. A SignerList must have at least 1 member and no more than 8 members. No address may appear more than once in the list, nor may the Account submitting the transaction appear in the list.

An account may not have more than one SignerList. A successful SignerListSet transaction replaces the existing SignerList, if one exists. To delete a SignerList, you must set SignerQuorum to 0 and omit the SignerEntries field. Otherwise, the transaction fails with the error temMALFORMED. A transaction to delete a SignerList is considered successful even if there was no SignerList to delete.

You cannot create a SignerList such that the SignerQuorum could never be met. The SignerQuorum must be greater than 0 but less than or equal to the sum of the SignerWeight values in the list. Otherwise, the transaction fails with the error temMALFORMED.

You can create, update, or remove a SignerList using the master key, regular key, or the current SignerList, if those methods of signing transactions are available.

You cannot remove the last method of signing transactions from an account. If an account's master key is disabled (it has the lsfDisableMaster flag enabled) and the account does not have a Regular Key configured, then you cannot delete the SignerList from the account. Instead, the transaction fails with the error tecNO_ALTERNATIVE_KEY.

With the MultiSignReserve amendment enabled, creating or replacing a SignerList enables the lsfOneOwnerCount flag on the SignerList object. When this flag is enabled, the XAG Ledger is able to lower the OwnerCount and owner reserve for a SignerList as provided by the MultiSignReserve amendment. For more information, see SignerList Flag.
