I've got a full bitcoind node with
listunspent command is useful only if node is in possession of a private key for address.
So, if I want to check UTXO for random address, it will not work until all of that UTXO is indexed properly.
So, are there any tools to do that simultaneously with bitcoind?
Of course there is an option to import that private key to bitcoind. But this question is larger - to get unspent for any address.
