'label' and 'account' APIs for wallet

A new 'label' API has been introduced for the wallet. This is intended as a replacement for the deprecated 'account' API. The 'account' can continue to be used in v0.20 by starting bitcoind with the '-deprecatedrpc=accounts' argument, and will be fully removed in v0.21.

The label RPC methods mirror the account functionality, with the following functional differences:

  • Labels can be set on any address, not just receiving addresses. This functionality was previously only available through the GUI.
  • Labels can be deleted by reassigning all addresses using the setlabel RPC method.
  • There isn't support for sending transactions from a label, or for determining which label a transaction was sent from.
  • Labels do not have a balance.

Here are the changes to RPC methods:

Deprecated Method New Method Notes
getaccount getaddressinfo getaddressinfo returns a json object with address information instead of just the name of the account as a string.
getaccountaddress n/a There is no replacement for getaccountaddress since labels do not have an associated receive address.
getaddressesbyaccount getaddressesbylabel getaddressesbylabel returns a json object with the addresses as keys, instead of a list of strings.
getreceivedbyaccount getreceivedbylabel no change in behavior
listaccounts listlabels listlabels does not return a balance or accept minconf and watchonly arguments.
listreceivedbyaccount listreceivedbylabel Both methods return new label fields, along with account fields for backward compatibility.
move n/a no replacement
sendfrom n/a no replacement
setaccount setlabel Both methods now:
  • allow assigning labels to any address, instead of raising an error if the address is not receiving address.
  • delete the previous label associated with an address when the final address using that label is reassigned to a different label, instead of making an implicit getaccountaddress call to ensure the previous label still has a receiving address.
Changed Method Notes
addmultisigaddress Renamed account named parameter to label. Still accepts account for backward compatibility if running with '-deprecatedrpc=accounts'.
getnewaddress Renamed account named parameter to label. Still accepts account for backward compatibility. if running with '-deprecatedrpc=accounts'
listunspent Returns new label fields. account field will be returned for backward compatibility if running with '-deprecatedrpc=accounts'
sendmany The account named parameter has been renamed to dummy. If provided, the dummy parameter must be set to the empty string, unless running with the -deprecatedrpc=accounts argument (in which case functionality is unchanged).
listtransactions The account named parameter has been renamed to dummy. If provided, the dummy parameter must be set to the string *, unless running with the -deprecatedrpc=accounts argument (in which case functionality is unchanged).
getbalance account, minconf and include_watchonly parameters are deprecated, and can only be used if running with '-deprecatedrpc=accounts'
