I’m engaged on a SegWit Bitcoin transaction, and I am encountering an error when attempting to broadcast it:
Code: -26, Error: mandatory-script-verify-flag-failed (Signature should
be zero for failed CHECK(MULTI)SIG operation)
Right here’s the code I’m utilizing to signal the transaction:
personal static void signInputsOfTransaction(Handle sourceAddress, Transaction tx, ECKey key) {
for (int i = 0; i < tx.getInputs().dimension(); i++) {
Script scriptPubKey = ScriptBuilder.createP2WPKHOutputScript(key);
Coin inputValue = tx.getInput(i).getValue();
Sha256Hash hash = tx.hashForWitnessSignature(
i, scriptPubKey, inputValue, Transaction.SigHash.ALL, false
);
ECKey.ECDSASignature ecdsaSignature = key.signal(hash);
TransactionSignature txSignature = new TransactionSignature(ecdsaSignature, Transaction.SigHash.ALL, false);
TransactionWitness witness = new TransactionWitness(2);
witness.setPush(0, txSignature.encodeToBitcoin());
witness.setPush(1, key.getPubKey());
tx.getInput(i).setWitness(witness);
tx.getInput(i).setScriptSig(ScriptBuilder.createEmpty());
}
}
Right here’s the uncooked transaction hex I’m attempting to broadcast:
010000000001011a34c12133e07aceb6b0cd254e2d9e12fde095b5a3afece4907945e36254e0d40100000000ffffffff02e803000000000000160014c9bf27c413655f5894a6a095ccfb5f1d291123f185170000000000001600146edda921d055dece3a894e39fd91a0c50faf675c02473044022000e9341c7c137529db50f706bc2bc1c1057674cda3bc33be5c559a45731b9c2802201a0f435a70e0f3a89d272efa407e0817e964f4c14ee9f9e3e4b5961fa658fc1d01210336069ac77986a9de47f0c371b682906149e43c2f51853b30d31132d1ec33b76900000000
I’ve decoded it utilizing a Bitcoin transaction API (BlockCypher), and right here’s the output:

Is there one thing unsuitable with the way in which I’m signing or establishing the TransactionWitness?
