Topic: Broadcasting signed transaction from Watching wallet using bitcoinj (Read 134 times)

Now i am sending tx using PeerGroup and transaction is commit to wallet and also broadcasted, but unable to receive payment on the other end.
My wallet says

>>> PENDING:
0.00 BTC total value (sends 0.00 BTC and receives 0.00 BTC)

its showing 0.00 BTC total value but i have sent 0.01 BTC
also i read about the conflict here https://github.com/bitcoinj/bitcoinj/blob/master/core/src/main/java/org/bitcoinj/core/TransactionConfidence.java
is my tx is correct now ?
or still some issues on it ?

also my broadcasting tx code is

SendRequest request = SendRequest.forTx(tx);
kit.wallet().commitTx(request.tx);ListenableFuture future = kit.peerGroup().broadcastTransaction(request.tx).future();
future.get();

I think it's because you're manually creating a fully complete and signed transaction... then trying to use SendRequest.forTX() which seems to want to actually include the inputs and sign the transaction for you.
So, possibly it is thinking you're just including the inputs you already have for the fee... and when it tries to find coins to attach to the output(s)... it can't as it's a watching-only wallet.


If you have already created and signed the transaction... I'd think you just want to use the PeerGroup.broadcastTransaction() method to simply broadcast the transaction you've already made.

I am working with watching wallet and Offline wallet using bitcoinj, I created Watching Wallet using tpub key of Offline Wallet

I am receiving payment on watching wallet Fine, now I want to spend coins from watching wallet after Signing my transaction from offline wallet

What I am doing is creating rawTx from the Watching Wallet and then signing it with the private key from Offline Wallet but when I broadcast it, it throws an exception:

InsufficientMoneyException

But my wallet balance is 0.23389 BTC , its not spendable balance as my watching wallet shows

Wallet containing 0.23389 BTC (spendable: 0.00 BTC)

This is not spendable because we cannot spend coins from watching wallet unless you sign it with the corresponding private key

Below is my code: As i am trying to sign transaction from my offline wallet, so i can spend coins from watching wallet

For creating Raw Transaction from Watching Wallet

private void bla()
{
    Coin coin = Coin.parseCoin("0.01");
    Address address = Address.fromBase58(params, "n4oLPFUGvohSdDxvJS3amXvfE1GEdZBddd");
    Transaction tx = new Transaction(params);
    System.out.println("Raw TX: " + tx.toString());
    byte[] bytes = Script.createInputScript("5ff01d61e67c706cb79653aa1e7ad2c7254b841167e0a34055504c35c7240469".getBytes()); // tx hash
    TransactionInput input = null;
    List list = kit.wallet().getTransactionsByTime();
    for(Transaction t: list)
    {
        input = t.getInput(0);
    }

    //Creates a scriptPubKey that encodes payment to the given address.
    Script scriptPubKey = ScriptBuilder.createOutputScript(address);
    // Signature Script
    Script scriptSig = input.getScriptSig();

    // Adding output that involves Amount and Script
    tx.addOutput(coin, scriptPubKey);
    System.out.println("Script pub key: " + scriptPubKey);

    //Adding input to the raw transaction
    tx.addInput(input);
    System.out.println("After adding inputs: " + tx.toString());
}

Signing Transaction from Offline Wallet Using Private Key

private String signTx()
{
    // TX Hash from Watching wallet
    String unSignHash = "f348ceadcb66e811799aa543107b63b9c92afebda5bc47d11222ba218df6638f";
    // Signing Hash with private key
    System.out.println("Signed Hash from prv key: " + DatatypeConverter.printHexBinary(prvKey().sign(Sha256Hash.wrap(unSignHash)).encodeToDER()));
}

Then I have added one more input in raw transaction

 input.setScriptSig(ScriptBuilder.createInputScript(new TransactionSignature(OfflineWallet.prvKey().sign(hash), Transaction.SigHash.ALL, true), OfflineWallet.ecKey()));
        tx.addInput(input);

After that my raw transaction looks like this

Then i am broadcasting it using

try
        {
            kit.wallet().sendCoins(SendRequest.forTx(tx));
        }
        catch (InsufficientMoneyException e)
        {
            e.printStackTrace();
        }

I am getting the exception here.

I don't know what I am doing wrong here, as I think my tx hash is just fine, all I have to do is broadcast the transaction into the network from watching wallet, which I am also doing but cannot succeed. I would really appreciate if someone helps me to find my mistake and broadcasting the signed transaction from watching wallet.
