I am complete one transaction using NBitcoin. Now it give new error when i spen 0.0001. ErrorCode: INSUFFICIENTFEE Error message: insufficient priority

Can any tell how to transfer fees to my address using NBitcoin.

[NicolasDorier]

You need to put more fees into your transaction, which, as my book says, is the difference between input and output.

Hi,

Thanks for reply. Can you tell me which code best for Transaction?

1. Transaction
2. TransactionBuilder.

Hi,

I am used this code it return success but not send bitcoin.

var txRepo = new NoSqlTransactionRepository(); //Let’s me introduce you, Alice, Bob, Satoshi, and Nico with their private keys. BitcoinSecret alice = new BitcoinSecret(""); BitcoinSecret satoshi = new BitcoinSecret("");

        var network = alice.Network;     

        Transaction aliceFunding = new Transaction()
        {
            Outputs =
                {
                    new TxOut("0.0009", alice.PrivateKey.PubKey)
                }
        };
        Coin[] aliceCoins = aliceFunding
                                .Outputs
                                .Select((o, i) => new Coin(new OutPoint(aliceFunding.GetHash(), i), o))
                                .ToArray();

        //Now Alice wants to send 1.00 BTC to Satoshi, with 0.001 BTC fees for miners.
        var txBuilder = new TransactionBuilder();
        var tx = txBuilder
            .AddCoins(aliceCoins)
            .AddKeys(alice.PrivateKey)
            .Send(satoshi.GetAddress(), "0.0002")
            .SendFees("0.0001")
            .SetChange(alice.GetAddress())
            .BuildTransaction(true);

        txRepo.Put(tx.GetHash(), tx);
        //Assert(txBuilder.Verify(tx)); //check fully signed
        Literal1.Text = tx.GetHash().ToString();

        var client = new QBitNinjaClient(network);
        BroadcastResponse broadcastResponse = client.Broadcast(tx).Result;

        if (!broadcastResponse.Success)
        {
            Literal1.Text = (string.Format("ErrorCode: {0}", broadcastResponse.Error.ErrorCode)).ToString();
            //Literal2.Text = ("Error message: " + broadcastResponse.Error.Reason).ToString();
        }
        else
        {
            Literal1.Text = ("Success! You can check out the hash of the transaciton in any block explorer:").ToString();
            //Literal2.Text = (transaction.GetHash()).ToString();
        }

[NicolasDorier]

please check https://www.gitbook.com/book/programmingblockchain/programmingblockchain/details there is a step by step way to send bitcoin. You do not have to use the txRepo. If it failed, you probably have either no enough fee, or spending a coin that has already been spent.

[hitjariwala]

i am see your book. it good

i am make first transaction using your code but cant make second transaction that why i use transactionbuilder. it return success but bitcoin not transfer to address.

please tell me if any issue in coding.

Thanks

[NicolasDorier]

give me your transaction in hex so I can check.

[NicolasDorier]

tx.ToHex()

Please also send me code for how to getbalance in this code. Transaction aliceFunding = new Transaction() { Outputs = { new TxOut("0.0009", alice.GetAddress()) } };

[NicolasDorier]

The input you are trying to spend does not exist in the blockchain a4095824a79246c065f5ebcc26462ff9d576db9d0802ad911bc80f94e1171495.

You can use

var coins = qbit.GetBalance(youaddress, true).Result.Operations.SelectMany(op => op.ReceivedCoins).ToArray();

to get the coins to spend.

[hitjariwala]

Thanks for fast reply.

Now code is working and completed transaction. check here https://www.smartbit.com.au/address/1rpYWDq48T84BzS2C5Hku8XA2htN57LAc

Now only one issue. How to spend transaction fees to my address?

[hitjariwala]

Hi,

[NicolasDorier]

You can't spend fee to your address, fees are for miners.

[hitjariwala]

Ok

I am create Webwallet Website. How to get transaction fees in Webwallet?

[hitjariwala]

Please check 1 day go and still transaction Unconfirm https://www.smartbit.com.au/tx/e84a0a0ed6b76450b1265eb9de0bf78fccbeb3d825b2b109753146331772a049

[hitjariwala]

I sent 0.0001 transaction fees. How to calculate fees?

[NicolasDorier]

some website can tell you like https://bitcoinfees.21.co/ or use bitcoind estimatefee rpc command.

[hitjariwala]

Can you tell me which API Best for Create Webwallet?

[NicolasDorier]

Yes. Do not create web wallets. And do not use third party API. Learn more about bitcoin before starting, your questions show lots of incomprehension yet. My book is a start, but search also other resources.

[hitjariwala]

Now i am use Bitgo API for create Webwallet.

[NicolasDorier]

Bitgo is reasonable. Never used it though.

[hitjariwala]

Please guide me which is best for create webwallet.

Please Skype hit.jariwala

[NicolasDorier]

sorry I don't have time to help you, read the documentation of bitgo.
