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

SignerListSet Fields

In addition to the common fields, SignerListSet transactions use 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 signer list, use the value `0`.
`SignerEntries`	Array	Array	(Omitted when deleting) Array of `SignerEntry` objects, indicating the addresses and weights of signers in this list. This signer list must have at least 1 member and no more than 32 members. No address may appear more than once in the list, nor may the `Account` submitting the transaction appear in the list. (Updated by the ExpandedSignerList amendment.)

A successful SignerListSet transaction replaces the account's SignerList object in the ledger, or adds one if it did not exist before. An account may not have more than one signer list. To delete a signer list, you must set SignerQuorum to 0 and omit the SignerEntries field. Otherwise, the transaction fails with the error temMALFORMED. A transaction to delete a signer list is considered successful even if there was no signer list to delete.

You cannot create a signer list 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 signer list using the master key, regular key, or the current signer list, 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 (the account has the lsfDisableMaster flag enabled) and the account does not have a Regular Key configured, then you cannot delete the signer list from the account. Instead, the transaction fails with the error tecNO_ALTERNATIVE_KEY.

Creating or replacing a signer list enables the lsfOneOwnerCount flag on the SignerList object. Lists that were created before the MultiSignReserve amendment became enabled do not have this flag and have a higher owner reserve. You can decrease the owner reserve for these lists by replacing the list with the same list. For more information, see SignerList Flags.
