The verification passed. But nothing happen after that. The balance in both accounts remain the same.

Anything wrong in the way that I build my transaction?

var fpk = new BitcoinSecret("<my private key>", Network.TestNet);
var fspk = fpk.GetAddress(ScriptPubKeyType.Legacy);
var api = new QBitNinjaClient("http://tapi.qbit.ninja/", fpk.Network);
var fbal = await api.GetBalance(fspk, true);
var fcoin = new List<ICoin>();
foreach (var o in fbal.Operations)
    if (o.Confirmations < 2) continue; // 2 confirmations

var builder = fpk.Network.CreateTransactionBuilder();
var tx = builder
    .AddKeys(new ISecret[] { fpk })
    .Send(new BitcoinPubKeyAddress("<To address>", fpk.Network), Money.Coins(0.001))

var r = await api.Broadcast(tx);

The response was success but with error code:

ErrorCode: INVALID

  • I have just noticed that my ErrorCode = Invalid, and Reason: Unknown, but my transaction did went through. I am confused now. – s k Apr 10 at 8:54
  • I am getting a different error when I run this code: Invalid base58 data – Prayank Apr 11 at 23:18
  • @Prayank You need to put in your own private and public keys into the code. – s k Apr 12 at 0:46
  • Yes I did that. Will share the code when I switch on my desktop again. On mobile right now. – Prayank Apr 12 at 1:08
  • Its working for me. No errors. Had to replace BitcoinPubKeyAddress with BitcoinWitPubKeyAddress. Code: pastebin.com/sQbdzmzL Tx: tbtc.bitaps.com/… – Prayank Apr 12 at 13:16
