I sent BTC from BreadWallet to Helix Light, and on to Abraxas.
The deposit never showed. Abraxas support says "All deposits should be already credited, if you are still missing one and is not visible in your abraxas balance history, please send us a transaction ID (txid) of missing deposit and we will take a look for you."
What transaction ID? There is no account used for Helix Light, so it's not like I can log in to anything to see a history. What do I do?
helix light gives you a tracking url and helix id. We can also find your transaction if you give us the helix address your sent the bitcoins to. First thing first are you sure you used the correct helix url?
