Signrawtransactionwithkey is returning "Unable to sign input, invalid stack size (possibly missing key)"

Node is Bitcoin Core 24.0. I'm trying to sign a raw transaction with private key that is not imported in the wallet.

Raw transaction hex: 0200000001d882ccfb5b012fc7f0ff80f88ad455397364b05924aa757eae6bc5ad686f02040100000000fdffffff0180841e00000000001976a9147270eaf36eb7849c81a1d21a8f4d15d81d03f54c88ac00000000

Decoded transaction:

bitcoin-cli decoderawtransaction "0200000001d882ccfb5b012fc7f0ff80f88ad455397364b05924aa757eae6bc5ad686f02040100000000fdffffff0180841e00000000001976a9147270eaf36eb7849c81a1d21a8f4d15d81d03f54c88ac00000000"

  • Is it possible to sign transactions without importing the key (that I sign with)?
  • What is the proper way to do it? (if not)

Tried different privkeys, txids to generate rawtransaction hex

Solution

  • Most likely, problem cause was either:

    • I was creating raw transaction in the wrong way.
    • Commission was too low.

    Although, both causes have different error messages. I can't reproduce the issue as of now.

    Syntax that works (1 utxo, 1 recipient):

    bitcoin-cli createrawtransaction '[{
            "txid" : "04026f68adc56bae7e75aa2459b064733955d48af880fff0c72f015bfbcc82d8",
            "vout" : 1
        }]' '{
      "n1cDpTFBVV3s7P1Bt7wKZrAjQpZBuGt2ya": 0.04893500
    }'

    Syntax that didn't work - 1 utxo, 1 recipient, 1 change recipient (same as utxo holder)

    bitcoin-cli createrawtransaction
    '[{
        "txid" : "04026f68adc56bae7e75aa2459b064733955d48af880fff0c72f015bfbcc82d8",
        "vout" : 1
    }]'
    '{"n1cDpTFBVV3s7P1Bt7wKZrAjQpZBuGt2ya": 0.03, 
    "mqx4bb2C4gZehqDoPKVZifkGXTdGghbPSZ": 0.01}'

    Summing up, you actually can sign transaction with key that is not imported using "signrawtransactionwithkey" on Core v24.0.
